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.

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
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
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.

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

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.

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.

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
- Tingling and numbness
- Muscle weakness
- Changes in mood or behavior
- 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.
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
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.
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
- 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 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.
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
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.
Although Keppra was well tolerated by participants, the
following adverse events were reported during trials:
- asthenia (lack or loss of strength)
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
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

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
- 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
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
- Don’t use artificial respiration unless breathing is absent
after muscle jerks subside, or unless water has been inhaled.
- Don’t restrain.

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.
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.
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.
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 and race do not affect the pharmacokinetics of levetiracetam.
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.
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.
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.
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.
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).
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.
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.
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.
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
Starting dose: 10 mg / kg twice a day
Maximum dose: 30 mg / kg twice a day
25 kg (1)
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.
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

Terminal stage – patients on dialysis *
5 00-1000 mg once a day **
* 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
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)
Ks = 0.55 for children under 13 and adolescent girls; in the case of adolescent boys, ks = 0.7.

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.
CC (ml / min) = [140-age (years)] × body weight (kg) / 72 × serum creatinine (mg / dL)
For women: obtained value x 0.85
Renal failure CC (ml / min) Dose and frequency of administration Norm> 80 500-1500 mg 2 times / day Latent 50-79 500-1000 mg 2 times / day Compensated 30-49 250-750 mg 2 times / day Intermittent 250-500 mg 2 times / day Terminal stage (patients on hemodialysis) * – 500-1000 mg 1 time / day **
* – 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.
Keppra Oral: uses, side effects, interactions, pictures, warnings and dosing –
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.
Use this medication regularly to get the most out of it. To help you remember, take it at the same time every day.
Do not increase your dose or use this medication more often or for longer than prescribed. Your condition will not improve any faster and your risk of side effects will increase.
