Understanding Keppra: An Overview of the Anticonvulsant Medication

Keppra, also known by its generic name levetiracetam, is a widely prescribed anticonvulsant medication used to treat epilepsy and seizures. Developed by UCB Pharma, Keppra has become a cornerstone in the management of various seizure disorders since its approval by the FDA in 1999. Its unique mechanism of action sets it apart from other antiepileptic drugs, making it an essential option for many patients.

Keppra works by binding to a synaptic vesicle protein called SV2A, which is involved in the release of neurotransmitters in the brain. By modulating this protein, Keppra helps to stabilize electrical activity in the brain, thereby reducing the likelihood of seizures. This mechanism is distinct from other anticonvulsants, which typically work by altering ion channels or enhancing inhibitory neurotransmission.

Key Features of Keppra:

  • Available in oral tablet, oral solution, and intravenous formulations
  • Approved for use in adults and children as young as 1 month old
  • Effective against partial-onset seizures, myoclonic seizures, and primary generalized tonic-clonic seizures
  • Generally well-tolerated with a favorable safety profile compared to some older anticonvulsants
  • Minimal drug-drug interactions, making it suitable for patients on multiple medications

Common Side Effects of Keppra: What Patients Should Expect

While Keppra is generally well-tolerated, like all medications, it can cause side effects in some patients. Understanding these potential side effects is crucial for both healthcare providers and patients to ensure proper management and adherence to treatment.

Most Frequently Reported Side Effects:

  1. Somnolence (drowsiness)
  2. Asthenia (weakness)
  3. Dizziness
  4. Headache
  5. Nausea

These common side effects typically occur within the first few weeks of treatment and often subside as the body adjusts to the medication. In clinical trials, approximately 15% of patients experienced somnolence, making it the most frequently reported side effect.

Can these side effects be managed effectively? In many cases, yes. Gradual dose titration, taking the medication with food, and adjusting the timing of doses can help alleviate some of these symptoms. It’s essential for patients to communicate with their healthcare provider about any persistent or bothersome side effects to explore potential solutions.

Behavioral Changes: A Unique Concern with Keppra

One of the more notable side effects associated with Keppra is the potential for behavioral changes, often referred to as “Keppra rage” or irritability. These changes can include:

  • Increased aggression
  • Mood swings
  • Anxiety
  • Depression
  • Irritability

While not experienced by all patients, these behavioral effects can be significant when they occur. Studies suggest that approximately 13% of patients may experience some form of behavioral change while taking Keppra. It’s crucial for patients, caregivers, and healthcare providers to be aware of these potential changes and monitor for them closely, especially in the early stages of treatment.

Rare but Serious Side Effects: When to Seek Medical Attention

While less common, Keppra can occasionally cause more severe side effects that require immediate medical attention. Recognizing these rare but serious effects is crucial for patient safety.

Serious Side Effects to Watch For:

  1. Severe allergic reactions (anaphylaxis)
  2. Suicidal thoughts or behaviors
  3. Severe skin reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis)
  4. Blood disorders (neutropenia, leukopenia)
  5. Liver dysfunction

How rare are these serious side effects? Severe allergic reactions and serious skin reactions occur in less than 1 in 1,000 patients. Suicidal thoughts or behaviors have been reported in approximately 1 in 500 patients taking antiepileptic drugs, including Keppra.

Patients should be advised to seek immediate medical attention if they experience symptoms such as:

  • Difficulty breathing or swallowing
  • Swelling of the face, lips, tongue, or throat
  • Severe rash or blistering of the skin
  • Unusual bruising or bleeding
  • Yellowing of the skin or eyes
  • Persistent mood changes or thoughts of self-harm

Drug Interactions: Navigating Keppra’s Impact on Other Medications

One of Keppra’s advantages is its relatively low potential for drug interactions compared to many other antiepileptic medications. This characteristic makes it a valuable option for patients who are taking multiple medications. However, it’s still important to be aware of potential interactions that can occur.

Key Interactions to Consider:

  1. Other antiepileptic drugs: While Keppra generally doesn’t significantly interact with other anticonvulsants, there may be additive effects on CNS depression.
  2. Methotrexate: Keppra may decrease the renal clearance of methotrexate, potentially increasing its blood levels.
  3. Probenecid: This medication can decrease the renal clearance of Keppra, potentially increasing its blood levels.
  4. Alcohol: Combining Keppra with alcohol can increase the risk of CNS depression and cognitive impairment.

How does Keppra’s interaction profile compare to other antiepileptic drugs? Unlike many older anticonvulsants, Keppra is not metabolized by the liver’s cytochrome P450 enzyme system, which significantly reduces its potential for drug interactions. This makes it less likely to interfere with the metabolism of other medications or be affected by them.

Despite this favorable profile, it’s crucial for patients to inform their healthcare providers about all medications, supplements, and herbal products they are taking to ensure comprehensive medication management.

Dosage and Administration: Optimizing Keppra Treatment

Proper dosing of Keppra is essential for maximizing its therapeutic benefits while minimizing the risk of side effects. The dosage can vary depending on factors such as the patient’s age, weight, kidney function, and the type of seizures being treated.

General Dosing Guidelines:

  • Adults and adolescents (≥16 years): Starting dose is typically 500 mg twice daily, which can be increased to a maximum of 3000 mg/day.
  • Children (4-15 years): Dosing is weight-based, usually starting at 10 mg/kg twice daily, with a maximum of 60 mg/kg/day.
  • Infants and young children (1 month to <4 years): Initial dose of 7 mg/kg twice daily, which can be increased to a maximum of 42 mg/kg/day.

How should Keppra be taken for optimal effectiveness? Keppra can be taken with or without food and should be swallowed whole if in tablet form. The oral solution should be measured carefully using the provided dosing device. It’s important to take Keppra at the same times each day to maintain consistent blood levels.

Dose adjustments may be necessary for patients with kidney impairment. In these cases, the dosage is typically reduced based on the patient’s creatinine clearance. Regular monitoring of kidney function is recommended for patients on long-term Keppra therapy.

Special Populations: Considerations for Pregnancy, Breastfeeding, and Elderly Patients

The use of Keppra in special populations requires careful consideration and individualized treatment approaches. This is particularly important for pregnant women, breastfeeding mothers, and elderly patients.

Pregnancy and Breastfeeding:

Keppra is classified as a Pregnancy Category C drug, meaning that animal studies have shown potential risks to the fetus, but human studies are limited. The decision to use Keppra during pregnancy should be based on a careful risk-benefit analysis.

Is Keppra safe during pregnancy? While no medication can be considered completely safe during pregnancy, Keppra is often considered one of the safer options among antiepileptic drugs. Studies have not shown a significant increase in major congenital malformations with Keppra use during pregnancy. However, there is a potential risk of developmental delays and behavioral issues in children exposed to Keppra in utero.

Regarding breastfeeding, Keppra does pass into breast milk. The American Academy of Pediatrics considers it usually compatible with breastfeeding, but infants should be monitored for potential side effects such as drowsiness or poor weight gain.

Elderly Patients:

Elderly patients may be more susceptible to certain side effects of Keppra, particularly CNS effects like dizziness and somnolence. Additionally, age-related declines in kidney function may necessitate dose adjustments.

How should Keppra treatment be approached in elderly patients? A “start low, go slow” approach is often recommended, with careful dose titration and monitoring for side effects. Regular assessment of kidney function is crucial, as is vigilance for potential drug interactions, given that many elderly patients are on multiple medications.

Long-term Effects and Monitoring: Ensuring Safe and Effective Keppra Use

While Keppra is generally considered safe for long-term use, ongoing monitoring is essential to ensure continued efficacy and to detect any potential long-term effects.

Key Aspects of Long-term Monitoring:

  1. Seizure control: Regular assessment of seizure frequency and severity
  2. Kidney function: Periodic blood tests to evaluate creatinine clearance
  3. Behavioral changes: Ongoing evaluation of mood, behavior, and cognitive function
  4. Blood counts: Monitoring for potential hematological effects
  5. Liver function: Periodic liver enzyme tests, although Keppra is not typically associated with hepatotoxicity

What long-term effects should patients and healthcare providers be aware of? While Keppra is not associated with significant long-term organ toxicity, some patients may experience persistent behavioral changes or cognitive effects. Additionally, there is a theoretical risk of osteoporosis with long-term use of antiepileptic drugs, including Keppra, although this risk appears to be lower than with enzyme-inducing anticonvulsants.

Regular follow-up appointments with a neurologist or epilepsy specialist are crucial for optimizing treatment and addressing any concerns that arise during long-term Keppra therapy. Patients should be encouraged to keep a seizure diary and report any new or worsening side effects promptly.

Keppra vs. Other Antiepileptic Drugs: Comparative Efficacy and Safety

Keppra’s unique mechanism of action and favorable side effect profile have made it a popular choice among antiepileptic drugs. However, it’s important to understand how it compares to other medications in terms of efficacy and safety.

Comparative Efficacy:

Studies have shown Keppra to be as effective as many traditional antiepileptic drugs in controlling seizures, particularly for partial-onset seizures. In some cases, it may even be more effective.

  • vs. Carbamazepine: Similar efficacy for partial seizures, with Keppra showing better tolerability
  • vs. Valproic Acid: Comparable efficacy for generalized seizures, with Keppra having a more favorable side effect profile
  • vs. Phenytoin: Similar efficacy, but Keppra has fewer drug interactions and less long-term toxicity concerns

How does Keppra’s efficacy compare in different types of seizures? Keppra has shown particular effectiveness in partial-onset seizures, juvenile myoclonic epilepsy, and as an add-on therapy for refractory epilepsy. It may be less effective for absence seizures compared to some other medications.

Safety Profile Comparison:

Keppra generally has a more favorable safety profile compared to many older antiepileptic drugs:

  • Fewer drug interactions due to its unique metabolism
  • Less risk of serious adverse effects like Stevens-Johnson syndrome (compared to carbamazepine)
  • Lower risk of cognitive impairment (compared to topiramate)
  • No significant effect on bone density (unlike enzyme-inducing anticonvulsants)

However, Keppra’s association with behavioral side effects, particularly irritability and aggression, is a unique concern that needs to be weighed against its benefits in individual cases.

Patient Education: Empowering Individuals on Keppra Therapy

Effective patient education is crucial for the success of Keppra therapy. Informed patients are more likely to adhere to their treatment regimen and report important side effects or concerns promptly.

Key Points for Patient Education:

  1. Importance of consistent dosing: Explain the need to take Keppra at the same times each day to maintain steady blood levels.
  2. Potential side effects: Discuss common side effects and when to seek medical attention for more serious symptoms.
  3. Behavioral changes: Educate patients and caregivers about the potential for mood or behavior changes and the importance of reporting these promptly.
  4. Interactions: Advise patients to consult their healthcare provider before starting any new medications or supplements.
  5. Pregnancy and breastfeeding: Discuss the importance of preconception planning and the need for close monitoring during pregnancy if Keppra is continued.

How can healthcare providers effectively communicate this information to patients? Using clear, non-technical language and providing written materials can be helpful. Some providers use teach-back methods, asking patients to explain key points in their own words to ensure understanding.

It’s also important to address common misconceptions about epilepsy and antiepileptic medications. For example, patients should understand that missing doses can increase the risk of seizures and that abruptly stopping Keppra can be dangerous.

Future Directions: Ongoing Research and Potential New Applications for Keppra

While Keppra has become a mainstay in epilepsy treatment, research continues to explore its potential in other neurological conditions and to refine its use in epilepsy management.

Emerging Areas of Research:

  • Neuroprotection: Studies are investigating whether Keppra may have neuroprotective properties that could be beneficial in conditions like stroke or traumatic brain injury.
  • Pain management: Some research suggests Keppra may have a role in treating certain types of neuropathic pain.
  • Anxiety disorders: Preliminary studies are exploring Keppra’s potential in treating anxiety, particularly in patients with epilepsy.
  • Alzheimer’s disease: There is ongoing research into whether Keppra could help reduce abnormal brain activity in Alzheimer’s patients.

    What is in this leaflet

    This leaflet answers some common questions about Keppra.

    It does not contain all the available information. It does not take the place of talking to your doctor
    or pharmacist.

    All medicines have risks and benefits. Your doctor has weighed the risks of you taking Keppra against the
    benefits they expect it will have for you.

    If you have any concerns about taking this medicine, ask your doctor or pharmacist.

    Keep this leaflet with the medicine. You may need to read it again.

    What Keppra is used for

    Keppra is used to control epilepsy.

    Epilepsy is a condition where you have repeated seizures (fits). There are many different types of
    seizures, ranging from mild to severe.

    Keppra belongs to a group of medicines called antiepileptics. These medicines are thought to work by
    controlling brain chemicals which send signals to nerves so that seizures do not happen.

    Keppra may be used alone, or in combination with other medicines, to treat your condition.

    Your doctor may prescribe Keppra in addition to your current therapy.

    Ask your doctor if you have any questions about why Keppra has been prescribed for you.

    There is no evidence that Keppra is addictive.

    This medicine is available only with a doctor’s prescription.

    The safety and effectiveness of Keppra has not been established in patients less than 4 years of age.

    Before you take Keppra
    When you must not take it

    Do not take Keppra if you have an allergy to:

    If you are unsure whether any of the above conditions apply to you, ask your doctor.

    Keppra oral solution contains maltitol. Do not use Keppra oral solution if you have hereditary
    problems of fructose intolerance.

    Do not take Keppra if you are pregnant or intend to become pregnant, without talking to your
    doctor first.

    Like most antiepileptic medicines, Keppra is not recommended for use during pregnancy. However, it is
    very important to control your fits while you are pregnant. If it is necessary for you to take Keppra, your
    doctor can help you decide whether or not to take it during pregnancy.

    Do not breastfeed while taking Keppra.

    Keppra passes into breast milk.

    Do not take Keppra after the expiry date (EXP) printed on the pack.

    Do not take Keppra tablets if the packaging is torn or shows signs of tampering or if the tablets
    do not look quite right.

    Do not take Keppra oral solution if the solution is not clear or the bottle shows signs of
    tampering


    If Keppra has expired or is damaged, return to your pharmacist for disposal.

    If you are not sure whether you should start taking Keppra, talk to your doctor or pharmacist.

    Before you start to take it

    Tell your doctor or pharmacist if you have allergies to:

    • any other medicines, especially barbiturates or any other anticonvulsant medicines
    • any other substances, such as foods, preservatives or dyes

    Tell your doctor if you have or have had any medical conditions, especially the following:

    • kidney problems (renal damage, renal insufficiency, impaired renal function)
    • liver problems

    Tell your doctor if you are pregnant or intend to become pregnant.

    Keppra may affect your developing baby if you take it during pregnancy. However, it is very important to
    control your fits while you are pregnant. If it is necessary for you to take Keppra, your doctor can help
    you decide whether or not to take it during pregnancy.

    Tell your doctor if you are breast-feeding or plan to breast-feed.

    It is recommended that you do not breastfeed while taking Keppra.

    If you have not told your doctor or pharmacist about any of the above, tell them before you start
    taking Keppra.

    Taking other medicines

    Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy
    without a prescription from your pharmacy, supermarket or health food shop.

    Keppra does not interact with the oral contraceptive pill. However, you may be given Keppra together with
    other antiepileptic drugs that do interact and they may compromise contraceptive efficacy.

    Your doctor may advise you to use an additional method of contraception if you take Keppra with other
    antiepileptic drugs.

    How to take Keppra
    How much to take

    For patients 12 years of age and older, the dosage is generally between 1000mg and 3000mg each day.

    For children 4 to 11 years of age the dose is 20 mg/kg to 60 mg/kg each day.

    There is no data to support the use of Keppra for patients less than 4 years of age.

    Your doctor will tell you how much Keppra you will need to take each day. This may depend on your age,
    your condition and whether or not you are taking any other medicines.

    Your doctor may recommend that you start with a low dose of Keppra and slowly increase the dose to the
    lowest amount needed to control your epilepsy/seizures (fits).

    Follow all directions given to you by your doctor carefully.

    They may differ from the information contained in this leaflet.

    If you believe that the effect of Keppra is too weak, talk to your doctor.

    If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

    How to take it

    Keppra Tablets

    Swallow Keppra tablets whole with a glass of water.

    Keppra Oral Solution

    Swallow Keppra oral solution undiluted or diluted in a glass of water.

    To take a dose of the oral solution, open the bottle by pressing the cap and turning it anticlockwise.

    Take the syringe and place it in the bottle.

    Fill the syringe with the liquid by pulling the piston up to the graduation mark corresponding to the
    dose in milligrams (mg) prescribed by your doctor

    Remove the syringe from the bottle and take the dose (undiluted or diluted in a glass of water).


    .

    When to take it

    Keppra must be taken two times a day, once in the morning and once in the evening, at about the
    same time each day.

    Taking Keppra at the same time each day will have the best effect. It will also help you remember when to
    take the tablets/oral solution.

    It does not matter if you take Keppra before or after food.

    If you forget to take it

    Contact your doctor if you have missed one or more doses.

    Do not take a double dose to make up for the dose that you missed.

    This may increase the chance of you getting an unwanted side effect.

    If you are not sure what to do, ask your doctor or pharmacist.

    If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

    How long to take it

    Most anticonvulsant medicines take time to work, so do not be discouraged if you do not feel better
    straight away.

    Continue taking Keppra for as long as your doctor tells you to.

    Keppra helps control your condition, but does not cure it. Therefore you must take your medicine every day,
    even if you feel well.

    Do not stop taking Keppra, or change the dosage, without checking with your doctor. Do not let
    yourself run out of medicine over the weekend or on holidays.


    Stopping Keppra suddenly may cause unwanted effects or make your condition worse. Your doctor will slowly
    reduce your dose before you can stop taking it completely.

    If you take too much (overdose)

    Immediately telephone your doctor if you think that you or anyone else may have taken too much
    Keppra. Do this even if there are no signs of discomfort or poisoning.

    If you take too much Keppra you may feel drowsy.

    While you are using Keppra
    Things you must do

    Tell your doctor immediately if you notice an increase in seizures (fits).

    Tell your doctor immediately if you have symptoms of depression or thoughts of self harm.

    Tell any other doctors, dentists, and pharmacists who are treating you that you are taking Keppra.

    If you are about to be started on any new medicine, tell your doctor, dentist or pharmacist that
    you are taking Keppra.

    Before you have any surgery or emergency treatment, tell your doctor or dentist that you are
    taking Keppra.

    Tell your doctor if you feel Keppra is not helping your condition.

    Your doctor may need to change your medicine.

    Tell your doctor if, for any reason, you have not taken Keppra exactly as prescribed.


    Otherwise, your doctor may change your treatment unnecessarily.

    If you become pregnant while taking Keppra, tell your doctor.

    Be sure to keep all of your doctor’s appointments so that your progress can be checked.


    Your doctor will check your progress and may want to take some tests from time to time. This helps to
    prevent unwanted side effects.

    Things you must not do

    Do not give Keppra to anyone else, even if their symptoms seem similar to yours or they have the
    same condition as you.

    Do not take Keppra to treat any other complaints unless your doctor tells you to.

    Do not stop using it unless your doctor tells you to.

    Things to be careful of

    Be careful driving or operating machinery until you know how Keppra affects you.

    As with other anticonvulsant medicines, Keppra may cause drowsiness in some people.

    This is more frequent at the beginning of treatment or at dosage increase.

    Make sure you know how you react to Keppra before you drive a car, operate machinery, or do anything else
    that could be dangerous if you are drowsy.

    Children should not ride a bike, climb trees or do anything else that could be dangerous if they
    are feeling drowsy or sleepy.


    Keppra may cause drowsiness and affect alertness.

    Be careful when drinking alcohol while taking Keppra.

    Combining Keppra and alcohol can make you more drowsy.

    Your doctor may suggest you avoid alcohol while you are being treated with Keppra.

    Side effects

    Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking
    Keppra.

    Keppra helps most people with epilepsy, but it may have unwanted side effects in a few people. All
    medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need
    medical treatment if you get some of the side effects.

    Ask your doctor or pharmacist to answer any questions you may have.

    If you get any side effects, do not stop taking Keppra without first talking to your doctor or
    pharmacist.

    Tell your doctor or pharmacist if you notice any of the following and they worry you:

    • dizziness
    • feeling weak
    • common cold and upper respiratory tract infections
    • feeling tired, drowsy or sleepy

    These are the more common side effects of Keppra. Mostly these are mild and short-lived.

    Other side-effects reported include:

    • mood changes such as depression, nervousness, aggression, anger, anxiety, confusion, hallucination,
      irritability

    Keppra oral solution includes methylhydroxybenzoate and parahydroxybenzoate which may cause allergic
    reactions, and maltitol which may have a mild laxative effect. Patients with rare hereditary problems of
    fructose intolerance should not take the oral solution.

    Keppra oral solution also contains glycerol which can cause headache, stomach upset and diarrhoea when
    ingested in doses greater than 10g. However, recommended doses of Keppra oral solution for children of 20kg
    or less contains less than 1.5g glycerol.

    You may not experience any of these side-effects.

    If you experience any other side-effects, tell your doctor immediately.

    If you experience more frequent or more severe seizures (fits), or thoughts of self harm tell your doctor
    immediately or go to Accident and Emergency at your nearest hospital.

    Tell your doctor if you notice anything else that is making you feel unwell.

    Other side effects not listed above may happen in some people.

    Some of these side effects can only be found when your doctor does tests from time to time to check your
    progress.

    After using Keppra
    Storage

    Keep your tablets in the pack or your solution in its original bottle until it is time to take
    it.


    If you take the tablets or solution out of their packs they will not keep well.

    Keep your tablets in a cool dry place where the temperature stays below 25°C.

    Keep your oral solution in a cool place where the temperature stays below 25°C and protect from
    light.

    Do not store Keppra or any other medicine in the bathroom or near a sink.

    Do not leave it on a window sill or in the car on hot days.

    Heat and dampness can destroy some medicines.

    Keep it where children cannot reach it.

    A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

    Disposal

    If your doctor or pharmacist tells you to stop taking Keppra or they have passed their expiry
    date, ask your pharmacist what to do with any that is left over.

    Mxing Alcohol & Keppra | The Recovery Village

    When people take medicines, whether prescription or otherwise, they often wonder if interactions with other drugs or substance — like alcohol — are possible. One such example is alcohol and Keppra. Read on for more information about the relationship between alcohol and the drug Keppra, and additional details about the side effects and withdrawal seizures related to this medicine.

    What Is Keppra?

    Keppra is a prescription medicine used to control the symptoms of epilepsy. Epilepsy refers to a condition where a person has repeated seizures, but the types of seizure can vary from mild to severe. This medicine is part of a class of drugs called antiepileptics, and it’s believed they work by controlling certain chemicals in the brain to make sure that seizures don’t happen. Sometimes Keppra is used alone, and other times it’s used in conjunction with other drugs. This anti-convulsant goes by the generic name levetiracetam, and it can be used in children and adults.

    There are a number of risks associated with Keppra, one of the worst being suicidal thoughts. Doctors warn patients to make sure they monitor their mood when they’re prescribed this medicine, watch for any changes and report them as they experience them. Keppra can also impair your reaction or confuse your thinking, so you should be aware of this if you take it and need to do something requiring you to be alert, such as driving.

    The makers of Keppra warn that if you become pregnant, it’s important to continue using this medicine unless your doctor says otherwise. This is because having a seizure while pregnant can be extremely dangerous for your baby.

    Outside of possible side effects of combining alcohol and Keppra, possible general side effects can include:

    • Feeling drowsy or weak
    • Bruising
    • Tingling and numbness
    • Muscle weakness
    • Changes in mood or behavior
    • Confusion
    • Hallucinations
    • Coordination problems
    • Problems with walking or movement
    • Skin reactions
    • Signs of infection

    If any of these side effects become severe, it’s important that you seek medical attention right away.

    Side Effects and Withdrawal Seizures

    There are two primary ways to approach conversations about alcohol and Keppra. The first thing people wonder about is whether or not you can use alcohol and Keppra at the same time, and what possible side effects might be. Then there’s the consideration of how Keppra is used as an alcoholic seizure treatment.

    Generally, it’s advised that you don’t take alcohol and Keppra at the same time. Both alcohol and Keppra effect the nervous system and they can heighten the side effects of each other. For example, if you were to combine alcohol and Keppra you could impair your judgment and thinking, and experience extreme dizziness, drowsiness, and problems with concentration. People are advised regarding alcohol and Keppra to limit their drinking while they’re taking the medication, particularly if they don’t know the effect it will have on them.

    There’s also something else related to alcohol and Keppra to consider. Keppra can be used to treat the side effects and withdrawal seizures associated with alcohol detox. Doctors and treatment centers often look for different options aside from benzodiazepines, because people can become addicted to them. In some cases, Keppra might be a safer option. Keppra is just one of the potential anticonvulsants that may be used during alcohol detox to manage potential seizures that can occur, and other options are available.

    With Keppra, one of the biggest risks is the possibility of mood swings and increases in suicidal thoughts. This is why a medically-supervised detox is so important during alcohol withdrawal. Your medical team can give you the medicines they think will be most appropriate for your symptoms, while also monitoring you for any potential side effects of those medications.

    Summing Up

    To sum up, what is Keppra? Keppra is an anti-seizure trmedicine. Alcohol and Keppra shouldn’t be used together because they can lead to intensified symptoms of intoxication, since both impact the central nervous system. There are some uses of Keppra to deal with the side effects and withdrawal seizures that come with alcohol detox, but this is something that should be monitored by a physician.

    Side effects and Dosage
    – Relievet

    With more than 5% of dogs suffering from seizures at some point in their life, there is a constant push to find safer and more effective ways to treat them. Seizures tend to occur when there is a change in brain activity, e.g. waking up, excited, and dog seizures while sleeping are also possible. Seizures are most common in dogs with epilepsy, which involves abnormal brain activity.

    Keppra for dogs is a relatively new drug often used alongside conventional anti-seizure medications, and it presents some benefits.

    We will explore Keppra’s side effects in dogs and how they compare to those of traditional anticonvulsant drugs.  

    What is Keppra for Dogs?

    Keppra is one of the brands which manufacture the drug Levetiracetam, a relatively new anticonvulsant used for dogs, cats, and people.

    Keppra for dogs is often used in combination with Phenobarbital or Potassium Bromide to treat seizures or epilepsy that is not responsive to these drugs, or for animals that have an adverse reaction to these drugs.

    Keppra differs from traditional anti-seizure medication in the fact that it does not contain either Potassium Bromide or Phenobarbital, which means it has a wider margin of safety, especially for dogs suffering from a damaged liver, or liver problems.  

    Keppra Dosage

    As a prescription drug, your veterinarian will direct you on the proper dosage of Keppra for dogs. Keppra comes in a tablet form ranging from 250mg to 1000mg, the extended-release pill comes in either 500mg or 750mg, and it is also available in an oral or injectable solution.

    The liver doesn’t process Keppra in the same way as traditional anticonvulsants, and it leaves the body more quickly. Because of this, it has a half-life of around four to six hours, meaning that it usually has to be dosed three times a day. While giving medication this often can be difficult, receiving each dose on time is important for controlling seizures.

    Like many drugs veterinarians prescribe to animals, Keppra is off label, meaning that the dosage and directions probably won’t match those on the label; this is common as drugs are usually developed for humans and then used on animals.  

    How long for Keppra to work in dogs?

    Keppra starts to work almost right away, and the regular tablets last around 8 hours. The extended-release tablets can last as long as 12 hours.

    Be aware that you cannot split the extended-release tablets; if you do, they will be absorbed too quickly and could lead to potential problems.  

    Side Effects of Keppra

    Similar to other anti-seizure medications such as Gabapentin for dogs, the most often experienced side effects of Keppra in dogs are drowsiness and loss of coordination.

    Unlike these drugs, Keppra isn’t thought to harm the liver or liver enzymes and is generally believed to have a better safety profile.

    Here are some other side effects to watch out for: 

    • Decrease Appetite
    • Drooling
    • Persistent Vomiting
    • Sudden Changes In Behavior

    Drug Interactions to be Aware of:

    You should always make your veterinarian aware of any other drugs your dog is taking, as Keppra can have potentially harmful interactions when used with the following medicines:

    Keppra overdose in dogs 

    You mustn’t stop giving Keppra (or other traditional anticonvulsants) to your dog suddenly, as this can cause withdrawal seizures. Always follow your veterinarian’s recommendations for dosage and on how to taper your dog off of this drug.

    Don’t give Keppra to dogs who are allergic to Levetiracetam and give cautiously to animals that are pregnant or suffer from kidney problems.  

    How much does Keppra for Dogs Cost?

    According to a popular discount prescription drug website, the average retail price of one 500mg tablet of Keppra is $41.99, with the lowest price being $15.97.

    However, there is a generic version of this drug, which is significantly cheaper; its average price comes in at $13.87, with the lowest price being $1.19 for a 500mg tablet.  

    Are there any Natural Alternatives?

    As with many drugs for the treatment of animals, we often look to human medication to see what the latest medications are; this is also true for natural alternative medicines.

    The FDA recently approved a drug called Epidiolex to treat people with seizures caused by two rare and severe forms of epilepsy. This drug’s active ingredient is CBD, which is an entirely natural hemp-derived compound.

    CBD has become widely available in recent years, in part due to its anti-seizure properties, and lack of severe side effects.

    CBD may have the potential to help some dogs suffering from seizures, but as with any serious health problem, you should never attempt to treat it without the guidance of your veterinarian.

    Keppra

    General Information

    Keppra is an antiepileptic drug to be used as an adjunctive
    therapy in adult patients with epilepsy for whom current therapies
    have not been effective in controlling partial seizures. Partial
    seizures, which are the most common type of seizures in adults, may
    be characterized by impaired consciousness, loss of awareness,
    involuntary motor behaviors, and other non-conscious, involuntary
    events. For physicians and patients, the attraction of Keppra is
    that it increases seizure control without adverse interaction with
    co-administered antiepileptic drugs.

    Epilepsy is caused by excessive electrical activity in the
    brain. Those who suffer from the disorder (2.3 million in America
    alone) experience recurring seizures. Even with treatment, only
    about 50% of epilepsy patients have complete control of their
    seizures, and 600,000 patients do not respond at all to the
    previously available therapies.

    Clinical Results

    Three clinical studies compared 3 distinct dosages of Keppra
    (1000 mg/day, 2000 mg/day, or 3000 mg/day) with a placebo. All of
    the 1393 epilepsy patients who participated in the trials had
    continued to experience seizures during the baseline period despite
    their being treated with 1-2 antiepileptic drugs. Concomitant AED
    regimens were held constant during administration of Keppra.
    Effectiveness of the Keppra therapy was measured primarily by
    reduction in weekly partial seizure frequency for the entire
    treatment period.

    Results of the trials indicated that Keppra significantly
    reduces the weekly seizure frequency over a placebo. Percent
    reduction ranged from 17.1% to 30.1% depending on the study number
    and the dose of Keppra in the treatment. In general, higher doses
    yielded greater reduction in number of seizures, although results
    varied over trials.

    Another appealing result of the trials was the overall lack of
    negative interaction when taken in conjunction with other AEDs.

    Side Effects

    Although Keppra was well tolerated by participants, the
    following adverse events were reported during trials:

    • somnolence
    • asthenia (lack or loss of strength)
    • infection
    • dizziness

    15% of patients receiving Keppra, compared to 11.6% of patients
    receiving the placebo treatment discontinued therapy or had the
    dose reduced as a result of an adverse effect.

    Exercise caution when giving Keppra to patients
    with moderate and severe renal impairment and patients undergoing
    hemodialysis, since levetiracetam is substantially excreted by the
    kidney.

    Mechanism of Action

    Keppra is rapidly absorbed after oral administration and food
    does not affect the extent of bioavailability. Pharmacokinetics are
    linear and steady state is achieved after two days of multiple
    twice daily dosing. Keppra is not protein bound (<10 percent
    bound) and its metabolism is not liver cytochrome P450 dependent,
    with sixty-six percent (66 percent) of the dose renally excreted
    unchanged. Plasma half-life of the medication is approximately 6 to
    8 hours but is increased in the elderly (due to age-related
    decrease in renal function) and in patients with renal impairment.
    Keppra is unlikely to produce, or be subject to, pharmacokinetic
    drug interactions. (From Doctor’s Guide to Medical and Other
    News)

    Additional Information

    This is what the Epilepsy Foundation says to do
    and not to do if you encounter a person having an
    epileptic seizure:

    What To Do:

    • Look for medical identification.
    • Protect from nearby hazards.
    • Loosen ties or shirt collars.
    • Protect head from injury.
    • Turn on side to keep airway clear unless injury exists.
    • Reassure as consciousness returns.
    • If a single seizure lasted less than 5 minutes, ask if hospital
      evaluation wanted.
    • If there are multiple seizures, or if one seizure lasts longer
      than 5 minutes, call an ambulance.
    • If person is pregnant, injured, or diabetic, call for aid at
      once.

    What Not To Do:

    • Don’t put any hard implement in the mouth.
    • Don’t try to hold tongue. It can’t be swallowed.
    • Don’t try to give liquids during or just after
      seizure,
    • Don’t use artificial respiration unless breathing is absent
      after muscle jerks subside, or unless water has been inhaled.
    • Don’t restrain.

    Pharmacological properties
    Pharmacokinetics
    Absorption

    After oral administration, levetiracetam is rapidly absorbed from the gastrointestinal tract. Absorption is complete and linear, which makes it possible to predict the concentration of the drug in serum based on the dose of levetiracetam taken, expressed in mg / kg of body weight. The degree of absorption does not depend on the dose and food intake. Bioavailability is about 100%.The maximum serum concentration (Cmax) is reached 1.3 hours after oral administration of a dose of 1000 mg and is 31 μg / ml; after a repeated dose – 43 μg / ml. The equilibrium state is reached after 2 days, the concentration is 270 ng / ml; after repeated use of a dose of 1000 mg – 308 ng / ml. Constant concentrations are achieved after 2 days when applied twice a day.

    Pharmacokinetics of levetiracetam in children is linear in the dose range 20–60 mg / kg / day; Cmax is reached after 0.5-1 hours.

    Distribution

    The degree of binding of levetiracetam and its main metabolite with blood plasma proteins is less than 10%. The volume of distribution (Vd) is approximately 0.5-0.7 l / kg, which is similar to the total volume of body fluid.

    Metabolism

    Levetiracetam is not extensively metabolized in the human body. The main metabolic mechanism (24%) is the enzymatic hydrolysis of the acetamide group, the metabolites of which are found in most tissues, including blood cells.The formation of the main, pharmacologically inactive metabolite (ucb L057) occurs without the participation of liver cytochrome P450.

    In vitro levetiracetam and its primary metabolites are not suppressed by cytochrome P450 isoforms (CYP3A4, 2A6, 2C9, 2C19, 2D6, 2E1, 1A2), glucuronide transferases (UGT1A1, UGT1A6) and epoxide hydroxylase. Levetiracetam does not affect valproic acid glucuronidation.

    In hepatocyte cell culture, levetiracetam has no or very low effect on CYP2B6 and CYP3A4.No significant interaction is expected between levetiracetam and oral contraceptives, warfarin, and digoxin. Therefore, interactions of levetiracetam with other substances are unlikely.

    Excretion

    The half-life (T½) in adults is 7 ± 1 hour and does not depend on the route of administration and the mode of use. The average systemic clearance is 0.96 ml / min / kg. 95% of the drug is excreted by the kidneys. Excretion in faeces is about 0.3% of the dose taken. The cumulative excretion of levetiracetam and its primary metabolites in the urine is 24-66% of the dose taken, mainly during the first 48 hours.The renal clearance of levetiracetam and its metabolite is 0.6 and 4.2 ml / min / kg, respectively.

    No changes in clearance are observed after repeated administration.

    Gender, race

    Gender and race do not affect the pharmacokinetics of levetiracetam.

    Elderly patients

    In elderly patients, T½ increases by 40% (up to 10-11 hours), which is associated with deterioration of renal functions in patients of this group.

    Renal impairment

    In patients with impaired renal function, the clearance of levetiracetam and its main metabolite correlates with creatinine clearance; therefore, it is recommended that the dose be adjusted in accordance with creatinine clearance in patients with renal insufficiency.In adults with end-stage renal failure, the T1 / 2 is 25 hours between dialysis sessions and 3.1 hours during dialysis. During a 4-hour dialysis session, up to 51% of levetiracetam is eliminated.

    Liver dysfunction

    In patients with mild to moderate hepatic dysfunction, no significant changes in the clearance of levetiracetam are observed. In most cases, with severe liver dysfunction and concomitant renal failure, the clearance of levetiracetam is reduced by 50%, mainly due to a concomitant deterioration in renal clearance.

    Children

    T½ in children (from 6 to 12 years old) after oral administration of a single dose of 20 mg / kg is about 5-6 hours. Systemic clearance in children is approximately 30% higher than in adults and is directly dependent on body weight. After repeated oral administration of the drug (from 20 to 60 mg / kg / day) by children with epilepsy (from 6 to 12 years), levetiracetam is rapidly absorbed. The peak plasma concentration is observed from 0.5 to 1.0 hours after taking the drug. There was a linear and dose-proportional increase in peak plasma concentration and area under the curve.The half-life is approximately 5 hours. The apparent clearance was 1.1 ml / min / kg.

    Pharmacodynamics
    Levetiracetam, the active ingredient of Keppra®, is a pyrrolidone derivative (S-enantiomer of α-ethyl-2-oxo-1-pyrrolidineacetamide), which differs from known antiepileptic drugs in structure. The mechanism of action of levetiracetam is not fully understood, but obviously differs from the mechanisms of action of existing antiepileptic drugs.

    Data from in vitro and in vivo studies suggest that levetiracetam does not affect basic cellular characteristics and normal neurotransmission.

    In vitro studies have shown that levetiracetam affects the concentration of Ca2 + ions in neurons, partially inhibiting the flow of Ca2 + ions through the N-type channels and suppressing the release of calcium from intraneuronal stores. In addition, levetiracetam partially restores the current through GABA and glycine-dependent channels, inhibited by the action of zinc and β-carbolines.

    One of the proposed mechanisms of action is based on the proven binding of the compound to the glycoprotein of SV2A synaptic vesicles located in the gray matter of the brain and spinal cord.Presumably, this explains the anticonvulsant effect, which is expressed in the prevention of hypersynchronization of neural activity. In addition, levetiracetam acts on GABA and glycine receptors, modulating them through various endogenous compounds. Levetiracetam does not affect normal neurotransmission, but it suppresses epileptiform neuronal outbreaks induced by the GABA agonist bicuculline, as well as the excitation of glutamate receptors. The activity of the drug has been proven in relation to both focal and generalized epileptic seizures (epileptiform manifestations / photoparoxysmal reaction).

    INDICATIONS
    as monotherapy in the treatment of:

    – partial seizures with secondary generalization OR WITHOUT adults and adolescents 16 years and older with newly diagnosed epilepsy

    as an auxiliary therapy for:

    – partial seizures With secondary generalization without it, adults, teenagers and children over 1 year with epilepsy

    – myoclonic seizures in adults and children over 12 years of age with juvenile myoclonic epilepsy

    – primary generalized tonic-clonic seizures in adults and children over 12 years WITH IDIOPATIC GENERALIZED EPILEPSY

    IN PATIENTS WITH DIFFICULT IN SWALLOWING IT IS POSSIBLE TO USE THE PREPARATION IN THE FORM OF INJECTION (ADULTS AND CHILDREN OVER 4 YEARS OLD).

    DOSAGE AND METHOD OF APPLICATION
    THERAPY MAY BEGIN WITH INTRAVENOUS OR Oral administration. TRANSITION TO ANOTHER FORM OF ADMINISTRATION SHOULD BE DIRECTED WITHOUT DOSE TITLING. IT IS NECESSARY TO ADHERE TO THE TOTAL DAILY DOSE AND THE FREQUENCY OF ADMINISTRATION. TABLETS OF THE PREPARATION KEPPRA® TAKE ORAL, REGARDLESS OF FOOD. DAILY DOSE IS DIVIDED INTO TWO SAME RECEPTIONS. TABLETS SHOULD BE DRINKED WITH SUFFICIENT QUANTITY OF LIQUID.

    Monotherapy
    Treatment of adults and adolescents over 16 years old begins with a daily dose of 500 mg, divided into two doses (½ tablet of 500 mg 2 times a day).After 2 weeks, the dose can be increased to an initial therapeutic dose of 1000 mg (500 mg twice a day). In the future, the dose may be increased by 250 mg every 2 weeks, depending on the clinical response to therapy. The maximum daily dose is 3000 mg (1500 mg twice a day).

    As adjunctive therapy

    Adults and adolescents 18 years and older and adolescents 12 to 17 years old weighing 50 kg or more

    Treatment should be started with a daily dose of 1000 mg, divided into two doses (500 mg twice per day).This dose should be administered on the first day of the course.

    Depending on the clinical response and tolerability of the drug, the dose can be increased to 1500 mg, administered twice a day. Dose adjustments (decrease or increase) in steps of 500 mg twice a day can be done every 2-4 weeks.

    Children

    The doctor should prescribe the drug in the most appropriate dosage form and dosage, based on the patient’s body weight, age and the required therapeutic dose.

    The tablet form of the drug is not intended for use in children under 6 years of age.Also, the tablet form of the drug is not suitable for children weighing less than 25 kg, patients who have difficulty swallowing, or those who are shown to prescribe a dose of less than 250 mg. In all of the above cases, it is necessary to use the drug in the form of a solution for oral administration.

    Monotherapy

    The efficacy and safety of Keppra® in children and adolescents under 16 years of age as monotherapy has not been established.

    Adjunctive therapy for children and adolescents weighing less than 50 kg

    The initial dose is 10 mg / kg of body weight twice a day.Depending on the clinical response and tolerability of the drug, the dose can be increased to 30 mg / kg body weight twice a day. The dose step for correction should not exceed 10 mg / kg of body weight twice a day every 2 weeks. The minimum effective dose should be used.

    The dose of the drug in children weighing 50 kg and above is similar to that for adults.

    Dosing recommendations for children and adolescents

    Weight

    Starting dose: 10 mg / kg twice a day

    Maximum dose: 30 mg / kg twice a day

    250 mg twice a day

    750 mg twice a day

    from 50 kg (2)

    500 mg twice a day

    1500 mg twice a day

    (1) – children under 25 kg or less, start treatment with levetiracetam solution for administration inside 100 mg / ml

    (2) – the dosage for children and adolescents weighing 50 kg or more is the same as in adults.

    Elderly patients

    Dose adjustment is recommended in case of impaired renal function.

    Patients with renal impairment

    The daily dose should be individualized according to the degree of renal dysfunction.

    Since levetiracetam is excreted by the kidneys, patients with renal insufficiency need to adjust the dose based on creatinine clearance.

    Creatinine clearance (CC) for adults and adolescents weighing more than 50 kg can be calculated based on the serum creatinine concentration using the following formula:

    [140 – age (years)] × body weight (kg)

    CC (ml / min) = ———————————————- ——–

    72 × serum CC (mg / dL)

    The creatinine clearance in women is calculated by multiplying the value obtained by 0.85.

    Correction for body surface area (BST) is performed according to the following formula:

    CC (ml / min)

    CC (ml / min / 1.73 m2) = ———– ————— x 1.73

    * On the first day of treatment, it is recommended to take a saturating dose of 750 mg

    ** After dialysis, it is recommended to take an additional dose of 250-500 mg

    Liver failure

    With mild and moderate impairment of liver function dose adjustment is not required.In patients with severely impaired liver function, a decrease in creatinine clearance may not fully reflect the degree of impaired renal function, therefore, in patients with creatinine clearance <60 ml / min / 1.73 m2, it is recommended to reduce the daily dose by 50%.

    In children with impaired renal function, the dose of levetiracetam should be adjusted according to the degree of renal impairment.

    Creatinine clearance (CC) in ml / min / 1.73 m2 in adolescents, children and infants can be calculated from serum creatinine levels (mg / dL) using the following formula (Schwartz formula):

    Height (cm) x ks

    CC (ml / min / 1.73 m2) = ————————-

    Serum creatinine (mg / dL)

After 2 weeks, the dose can be increased to the initial therapeutic dose – 1 g (500 mg 2 times / day). The maximum daily dose is 3 g (1.5 g 2 times / day).

    As part of complex therapy

    For children aged 1 month to 6 months, the drug is prescribed in the form of a solution for oral administration. The initial therapeutic dose is 7 mg / kg 2 times / day. Depending on the clinical efficacy and tolerability, the dose may be increased to 21 mg / kg 2 times / day. Dose changes should not exceed plus or minus 7 mg / kg 2 times / day every 2 weeks. The minimum effective dose should be prescribed.

    Recommendations for the dosage of Keppra® in the form of an oral solution for children under 6 months of age are presented in the table.

    Body weight Initial dose: 7 mg / kg 2 times / day Maximum dose: 21 mg / kg 2 times / day 4 kg 28 mg (0.3 ml) 2 times / day 84 mg (0.85 ml) 2 times / day 5 kg 35 mg (0.35 ml) 2 times / day 105 mg (1.05 ml) 2 times / day 7 kg 49 mg (0.5 ml) 2 times / day 147 mg (1.5 ml) 2 times / day

    In children aged 6 months to 23 months, children aged 2 to 11 years and adolescents from 12 years to 17 years with a body weight of less than 50 kg, treatment should be started with a dose of 10 mg / kg of body weight, divided into 2 doses (10 mg / kg of body weight 2 times / day).Depending on the clinical response and tolerability of the drug, the daily dose may be increased to 30 mg / kg 2 times / day. A dose change of 10 mg / kg body weight can be done every 2 weeks. The minimum effective dose should be used.

    Doses for children weighing 50 kg or more are the same as for adults.

    Recommended doses for children from 6 months of age and adolescents are presented in the table.

    Body weight Initial dose: 10 mg / kg 2 times / day Maximum dose: 30 mg / kg 2 times / day 6 kg 60 mg (0.6 ml) 2 times / day 180 mg (1.8 ml) 2 times / day 10 kg 100 mg (1 ml) 2 times / day 300 mg (3 ml) 2 times / day 15 kg 150 mg (1.5 ml) 2 times / day 450 mg (4.5 ml) 2 times / day 20 kg 200 mg (2 ml) 2 times / day 600 mg (6 ml) 2 times / day 25 kg 250 mg 2 times / day 750 mg 2 times / day from 50 kg 500 mg 2 times / day 1500 mg 2 times / day

    Children over 4 years of age should begin treatment with a daily dose of 20 mg / kg of body weight, divided into 2 doses (10 mg / kg of body weight 2 times / day). A dose change of 20 mg / kg of body weight can be carried out every 2 weeks until the recommended daily dose is reached – 60 mg / kg of body weight (30 mg / kg of body weight 2 times / day).In case of intolerance to the recommended daily dose, it may be reduced. The minimum effective dose should be used.

    The drug should be prescribed in the most appropriate dosage form and dose, depending on the patient’s body weight and the required therapeutic dose.

    Children weighing ≤ 20 kg are recommended to start treatment with the drug in the form of an oral solution.

    For children weighing> 50 kg, dosing is carried out according to the scheme given for adults.

    Adults and adolescents over 16 years of age weighing more than 50 kg should begin treatment with a daily dose of 1 g, divided into 2 doses (500 mg 2 times / day). Depending on the clinical response and tolerability of the drug, the daily dose can be increased to a maximum of 3 g (1.5 g 2 times / day). A dose change of 500 mg 2 times / day can be carried out every 2-4 weeks.

    Since levetiracetam is excreted by the kidneys when the drug is prescribed to elderly patients and patients with renal insufficiency, the dose should be adjusted depending on the CC value.

    CC can be calculated from the serum creatinine concentration using the following formula.

    For men:

    CC (ml / min) = [140-age (years)] × body weight (kg) / 72 × serum creatinine (mg / dL)

    For women: obtained value x 0.85

    * – on the first day of treatment with Keppra® it is recommended to take a saturating dose of 750 mg.

    ** – after dialysis it is recommended to take an additional dose of 250-500 mg.

    For children with renal impairment, the dose of levetiracetam should be adjusted according to the degree of renal impairment, using the recommendations given for adults.

    Patients with mild to moderate hepatic impairment do not need to adjust the dosage regimen. In patients with decompensated liver dysfunction and renal insufficiency, the CC value may not reflect the true degree of renal dysfunction, therefore, with CC

    Rules for using the drug

    Tablets should be taken orally with a sufficient amount of liquid, regardless of food intake.

    Dosing of the solution is carried out using a measuring syringe with a nominal capacity of 10 ml (corresponds to 1 g of levetiracetam) and with a graduation value of 25 mg (corresponds to 0.25 ml), which is included in the delivery kit of the drug. The measured dose of the drug is diluted in a glass of water (200 ml).

    To dispense the solution using a measuring syringe, open the bottle: to do this, press the cap and turn it counterclockwise. Insert the syringe adapter into the neck of the vial, then take the syringe and place it in the adapter.Turn the bottle upside down. Fill the syringe with a small amount of solution by pulling the plunger down, then push the plunger up to remove any air bubbles. Pulling the plunger, fill the syringe with the solution until the division corresponds to the number of ml of solution prescribed by the doctor. Remove the syringe from the adapter. Introduce the contents of the syringe into a glass of water, pushing the plunger all the way. Drink the entire contents of the glass. Then rinse the syringe with water and close the bottle with a plastic cap.

    Benefits

    Levetiracetam is used with other drugs to treat seizures (epilepsy).It belongs to a class of medications known as anticonvulsants. Levetiracetam may reduce the number of seizures you have.

    How to use Keppru

    Before you start taking levetiracetam and each time you receive a drug, read the Medication Guide and, if possible, the patient information leaflet provided by your pharmacist. If you have any questions, ask your doctor or pharmacist.

    Take liquid and regular-release tablets by mouth as directed by a healthcare practitioner, usually twice daily with or without food.Crushing or chewing a tablet can cause a bitter taste.

    If you are using the liquid form of this medication, carefully measure the dose with a special measuring instrument / spoon. Don’t use a homemade spoon because you can’t get the right dose.

    If you are using extended-release tablets, take this medication as directed by your doctor, usually once a day. Do not crush or chew extended-release tablets. This can cause all of the drugs to be released in one go, increasing the risk of side effects.Do not split tablets unless they have a rating line and your doctor or pharmacist tells you to do so. Swallow a whole or split tablet without crushing or chewing.

    The dosage depends on your medical condition and response to treatment. Dosage in children is also based on weight. To reduce the risk of side effects (such as dizziness and drowsiness), your doctor may instruct you to start taking this drug at a low dose and gradually increase your dose.Follow your doctor’s instructions carefully.
