Understanding Skelaxin: A Powerful Muscle Relaxant

Skelaxin, also known by its generic name metaxalone, is a prescription medication primarily used as a muscle relaxant. It belongs to a class of drugs called skeletal muscle relaxants and is commonly prescribed to alleviate pain and discomfort associated with acute musculoskeletal conditions.

How does Skelaxin work? The exact mechanism of action is not fully understood, but it is believed to work by depressing the central nervous system, particularly at the level of the spinal cord and subcortical areas of the brain. This action helps to reduce muscle spasms and associated pain without causing complete paralysis of the affected muscles.

Key Features of Skelaxin

  • Generic Name: Metaxalone
  • Drug Class: Skeletal muscle relaxant
  • Available Forms: Oral tablets
  • Prescription Required: Yes
  • FDA Approved: 1962

Indications and Uses of Skelaxin

Skelaxin is primarily prescribed for the treatment of acute, painful musculoskeletal conditions. These conditions often involve muscle spasms, which can cause significant discomfort and limit mobility.

When is Skelaxin typically prescribed? Healthcare providers may recommend Skelaxin for:

  • Muscle strains and sprains
  • Lower back pain
  • Neck pain
  • Fibromyalgia-related muscle pain
  • Tension headaches associated with muscle tension

Is Skelaxin used as a standalone treatment? While Skelaxin can be effective on its own, it is often used as part of a comprehensive treatment plan. This plan may include rest, physical therapy, and other pain management strategies to provide optimal relief and promote healing.

Proper Dosage and Administration of Skelaxin

The correct dosage of Skelaxin can vary depending on the individual patient and the specific condition being treated. It’s crucial to follow the prescribing physician’s instructions carefully.

Standard Dosing Guidelines

  • Typical adult dosage: 800 mg 3-4 times daily
  • Maximum daily dose: 3200 mg
  • Duration of treatment: Usually 2-3 weeks, or as directed by a healthcare provider

How should Skelaxin be taken? Skelaxin tablets should be swallowed whole with a full glass of water. They can be taken with or without food, but taking them with food may help reduce the risk of stomach upset.

Can the dosage be adjusted? The dosage may be adjusted based on the patient’s response to the medication and the severity of their condition. Any changes to the dosage should only be made under the guidance of a healthcare professional.

Potential Side Effects and Adverse Reactions

Like all medications, Skelaxin can cause side effects. While not everyone experiences these side effects, it’s important to be aware of them and report any concerning symptoms to a healthcare provider.

Common Side Effects

  • Drowsiness or dizziness
  • Headache
  • Nausea or vomiting
  • Gastrointestinal discomfort
  • Irritability or nervousness

Serious Side Effects

While rare, some patients may experience more serious side effects that require immediate medical attention:

  • Allergic reactions (rash, itching, swelling, severe dizziness, difficulty breathing)
  • Jaundice (yellowing of the skin or eyes)
  • Unusual bleeding or bruising
  • Signs of liver problems (persistent nausea/vomiting, loss of appetite, severe stomach/abdominal pain, dark urine)

Is there a risk of dependence with Skelaxin? Unlike some other muscle relaxants, Skelaxin is not considered habit-forming. However, it should still be used only as prescribed and for the shortest duration necessary to alleviate symptoms.

Drug Interactions and Precautions

Skelaxin can interact with various medications and substances, potentially altering its effectiveness or increasing the risk of side effects. It’s crucial to inform your healthcare provider about all medications, supplements, and herbal products you are taking.

Notable Drug Interactions

  • MAO inhibitors (e.g., isocarboxazid, phenelzine)
  • Serotonergic drugs (e.g., SSRIs, SNRIs, triptans)
  • CNS depressants (e.g., alcohol, benzodiazepines, opioids)
  • Certain antibiotics (e.g., erythromycin, clarithromycin)
  • Antifungal medications (e.g., ketoconazole, itraconazole)

How can drug interactions be managed? Your healthcare provider may need to adjust dosages, monitor you more closely, or choose alternative medications to avoid potential interactions. Never start or stop any medication without consulting your doctor.

Special Precautions

Certain individuals may need to use Skelaxin with caution or avoid it altogether:

  • Pregnant or breastfeeding women
  • Individuals with liver or kidney disease
  • People with a history of drug abuse or addiction
  • Elderly patients, who may be more sensitive to the drug’s effects
  • Individuals with certain genetic enzyme deficiencies

Proper Storage and Disposal of Skelaxin

Proper storage and disposal of Skelaxin are essential to maintain its effectiveness and prevent accidental ingestion or misuse.

Storage Guidelines

  • Store at room temperature (between 68째F to 77째F or 20째C to 25째C)
  • Keep away from moisture and direct light
  • Store in the original container with the lid tightly closed
  • Keep out of reach of children and pets

Disposal Instructions

How should unused or expired Skelaxin be disposed of? The FDA recommends the following steps:

  1. Remove the medication from its original container and mix it with an undesirable substance, such as used coffee grounds or kitty litter.
  2. Place the mixture in a sealed plastic bag or container to prevent the drug from leaking.
  3. Throw the container in your household trash.
  4. Remove or scratch out all personal information on the empty medication container before disposing of it.

Can Skelaxin be flushed down the toilet? Generally, it’s not recommended to flush medications down the toilet unless specifically instructed to do so. This practice can contaminate water supplies and harm aquatic life.

Overdose Risk and Emergency Situations

While Skelaxin is generally considered safe when used as prescribed, an overdose can occur, particularly if it’s taken in large quantities or combined with other CNS depressants.

Symptoms of Overdose

  • Severe drowsiness or dizziness
  • Confusion or disorientation
  • Seizures
  • Difficulty breathing
  • Loss of consciousness

What should you do in case of an overdose? If you suspect an overdose of Skelaxin, seek emergency medical attention immediately. Call your local poison control center or emergency room right away.

Emergency Preparedness

To be prepared for potential emergencies:

  • Keep the number of your local poison control center easily accessible
  • Inform family members or roommates about your medication regimen
  • Consider wearing a medical alert bracelet if you’re on multiple medications

Patient Education and Counseling Points

Proper education and counseling can significantly improve the safe and effective use of Skelaxin. Healthcare providers should discuss the following points with patients:

Key Counseling Points

  • The importance of taking Skelaxin exactly as prescribed
  • Potential side effects and when to seek medical attention
  • The need to avoid alcohol and other CNS depressants while taking Skelaxin
  • The importance of informing all healthcare providers about Skelaxin use
  • The need for caution when driving or operating machinery, as Skelaxin can cause drowsiness

How can patients ensure they’re using Skelaxin safely? Patients should keep a medication log, including all prescription and over-the-counter drugs, as well as any supplements they’re taking. This log should be shared with all healthcare providers to prevent potential drug interactions.

Lifestyle Modifications

In addition to medication, patients should be counseled on lifestyle modifications that can support their treatment:

  • Proper posture and body mechanics
  • Stress reduction techniques
  • Regular, gentle exercise as approved by their healthcare provider
  • Use of heat or cold therapy for muscle pain
  • Adequate rest and sleep

Skelaxin, when used appropriately and in conjunction with other treatment modalities, can be an effective tool in managing acute musculoskeletal pain. However, it’s crucial for patients to understand the medication’s proper use, potential risks, and the importance of open communication with their healthcare providers. By following these guidelines and maintaining a collaborative relationship with their medical team, patients can maximize the benefits of Skelaxin while minimizing potential risks.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor’s approval.

Some products that may interact with this drug include: diet pills/appetite suppressants (such as diethylpropion), drugs for attention deficit disorder (such as atomoxetine, methylphenidate), apraclonidine, bupropion, buspirone, carbamazepine, cyclobenzaprine, deutetrabenazine, a certain combination product (dextromethorphan/quinidine), levodopa, maprotiline, methyldopa, metoclopramide, certain opioid pain relievers (such as fentanyl, meperidine, methadone, tapentadol), certain drugs for Parkinson’s disease (such as entacapone, tolcapone), certain supplements (such as tryptophan, tyramine), tetrabenazine, tricyclic antidepressants (such as amitriptyline, doxepin), valbenazine.

The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/”ecstasy,” St. John’s wort, certain antidepressants (including mirtazapine, SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), tramadol, certain “triptans” used to treat migraine headaches (such as rizatriptan, sumatriptan, zolmitriptan), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.

Some products can interact with metaxalone if you take them together, or even if you take them weeks before or after taking metaxalone. Tell your doctor or pharmacist if you take anything in the list of products that may interact with this drug, or any of the products that increase serotonin, within 2 weeks before or after taking metaxalone. Also tell them if you have taken fluoxetine within 5 weeks before starting metaxalone. Ask your doctor how much time to wait between starting or stopping any of these drugs and starting metaxalone.

Taking other MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Do not take any other MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before and after treatment with this medication. Ask your doctor when to start or stop taking this medication.

Before using metaxalone, report the use of drugs that may increase the risk of extremely high blood pressure (hypertensive crisis) when combined with metaxalone, including herbal products (such as ephedra/ma huang), nasal decongestants (such as phenylephrine, pseudoephedrine), and stimulants (such as amphetamines, ephedrine, epinephrine, phenylalanine). Metaxalone should not be used with any of these medications. Talk to your doctor or pharmacist for more details.

Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), other muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine).

Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely.

This medication may interfere with certain lab tests (such as certain urine glucose tests), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.

    Have you ever had a back thrust, injury or sprain where you feel like your muscles are twitching and becoming so tight that you can’t move? In this case, your doctor may have prescribed a muscle relaxant to help relieve your symptoms.

    Skelaxin and Flexeril are two FDA-approved drugs for the treatment of muscle spasms. They are in a group of medications called skeletal muscle relaxants. Skelaxin and Flexeril are most often prescribed as their analogues, metaxalone and cyclobenzaprine. How they work is not fully understood, but may be associated with central nervous system (CNS) depression and sedative effects. These medicines do not act directly on muscles or nerves.

    Although both drugs are muscle relaxants, they are not exactly the same. Continue reading below to learn more about Skelaxin and Flexeril.

    What are the main differences between Skelaxin and Flexeril?

    Skelaxin is a skeletal muscle relaxant containing metaxalone. It is available as brand name tablets and generic tablets. Skelaxin is used for short-term treatment.

    Flexeril is also a skeletal muscle relaxant – the active ingredient is cyclobenzaprine. Flexeril is no longer sold as a branded product. Flexeril is only available as generic cyclobenzaprine. Cyclobenzaprine is also available in an extended release form under the brand name Amrix. Flexeril is used for short-term treatment – according to the manufacturer, Flexeril should not be taken for more than two to three weeks.

    902 80 Drug interactions of Skelaxin and Flexeril

    Skelaxin and Flexeril may increase the effects of alcohol, barbiturates, and other CNS depressants such as benzodiazepines, opioids, antihistamines, and sedative-hypnotics.

    There is an increased risk of serotonin syndrome when taking Skelaxin or Flexeril with other drugs that increase serotonin levels; such as SSRIs, SNRIs, or tricyclic antidepressants; triptans for migraine; or cough and cold medicines containing dextromethorphan.

    Flexeril is structurally similar to tricyclic antidepressants (such as amitriptyline and nortriptyline). Because of this, there is an increased risk of seizures when taking tramadol.

    Both skelaxin and flexeril interact with tramadol (and other opioids) – there is an increased risk of serotonin syndrome, as well as additive CNS depression.

    This is not a complete list of drug interactions. Check with your healthcare provider about drug interactions.

    Skelaxin and flexeril warnings or kidney or anemia.

  • Taking Skelaxin with food can significantly increase the effect of CNS depression. Elderly patients are more susceptible to this effect.
  • Flexeril

    • Do not take an MAO inhibitor within 14 days of taking Flexeril – the combination may cause convulsions and death.
    • Patients with hyperthyroidism, heart failure, or other heart or rhythm problems should not take Flexeril. Flexeril should be used with caution in elderly patients and patients with liver problems. Do not use the extended release form (Amrix) in patients with liver problems.
    • Use Flexeril with caution in patients with a history of urinary retention, angle-closure glaucoma, elevated intraocular pressure, and in patients taking anticholinergics.
    • When discontinuing Flexeril, withdrawal symptoms should be considered. Stopping the medicine too quickly can cause headache, fatigue, and nausea.
    • Swallow Amrix (extended release cyclobenzaprine) capsules whole. Do not chew or crush.

    Skelaxin and Flexeril General Warnings

    • Both drugs are on the Beer Criteria list, which means they are potentially unsuitable for the elderly (age 65 and over). Most older people do not tolerate muscle relaxants well due to serious side effects, sedation, and an increased risk of fractures. Efficacy at doses that can be tolerated in this age group is also questionable.
    • Death from overdose (intentional or accidental) has occurred with Skelaxin or Flexeril, especially when combined with antidepressants or alcohol. Monitor patients closely.
    • Possible serotonin syndrome. Patients and their caregivers should be aware of symptoms (sweating, fever, agitation, changes in blood pressure or heart rate, tremors, nausea, vomiting, diarrhea) and seek immediate medical attention if symptoms occur. Serotonin syndrome is more likely if you are taking skelaxin or flexeril in combination with other drugs that increase serotonin levels, such as certain antidepressants, triptans, or cough and cold medicines containing dextromethorphan.
    • Do not drive or operate machinery until you know how you react to skelaxin or flexeril. Both drugs cause drowsiness and dizziness.

    Frequently asked questions about Skelaxin and Flexeril

    What is flexeril?

    Flexeril is also a muscle relaxant used to treat skeletal muscle spasms. Flexeril’s generic name is cyclobenzaprine.

    Are Skelaxin and Flexeril the same thing?

    Is Skelaxin or Flexeril better?

    There are no data directly comparing the two drugs in terms of pain relief. Therefore, if you need a muscle relaxant, your healthcare provider will review your symptoms, conditions, and any medications you are taking (which may interact with skelaxin or flexeril) to determine if one of these medications is right for you.

    Can I use skelaxin or flexeril during pregnancy?

    B The skelaxin manufacturer’s information states that post-marketing experience has not shown evidence of fetal injury, but such experience cannot rule out the possibility of infrequent or minor injury to the human fetus. The safe use of metaxalone has not been established with regard to possible adverse effects on fetal development. Therefore, skelaxin is not recommended for pregnant women (especially in early pregnancy) or women who may become pregnant, unless your healthcare provider determines that the benefits outweigh the risks.

    B Manufacturer’s Information Flexeril states that there are no adequate, well-controlled studies in pregnant women. Therefore, Flexeril should be used by pregnant women only when absolutely necessary.

    Can I use skelaxin or flexeril with alcohol?

    No. Using skelaxin or flexeril with alcohol may increase side effects such as dizziness and drowsiness. It can also lead to lack of coordination, which can lead to an accident. In addition, taking a muscle relaxant with alcohol may increase the chance of abuse or dependence.
