Skelaxin (generic name metaxalone) is a centrally acting skeletal muscle relaxant prescribed as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions. It does not directly relax tense muscles in the way that a local anesthetic or nerve block might. Rather, metaxalone appears to exert its effect at the level of the central nervous system, reducing the perception of pain and dampening reflexes that contribute to muscle spasm and tightness. Although the precise mechanism of action has not been fully elucidated, its clinical utility is well established for short-term relief of muscle spasm due to strains, sprains, and other minor musculoskeletal injuries.
Patients commonly use Skelaxin for acute lower back pain, neck strain (whiplash), shoulder sprain, sports-related muscle injuries, or postural muscle spasm following overuse. Because musculoskeletal pain is multifactorial—often involving inflammation, muscle spasm, and pain signaling—Skelaxin is best employed as part of a comprehensive plan that can include:
Skelaxin is not indicated for chronic pain syndromes or long-term daily use. Its benefits are most pronounced during the acute phase of musculoskeletal injury, typically a period of days to a few weeks, depending on clinical guidance.
Brand-name Skelaxin and generic metaxalone tablets contain the same active ingredient. Many patients opt for the generic due to cost savings, while maintaining comparable efficacy and safety when used as directed.
The usual adult dose of metaxalone is 800 mg taken orally three to four times daily. Your healthcare provider will individualize the regimen based on symptom severity, concomitant medications, age, and overall health status. Do not exceed the prescribed dose or frequency.
Administration tips:
Special populations:
Always follow your prescriber’s instructions exactly. If you feel the medication is too strong or weak, or if side effects are troublesome, consult your clinician before making any changes.
Before starting Skelaxin (metaxalone), share your full medical history and medication list with your healthcare provider to mitigate risks and interactions. Consider the following precautions:
If you develop yellowing of the skin or eyes, dark urine, right upper abdominal pain, unusual bleeding or bruising, severe fatigue, confusion, or worsening depression, stop the medication and seek medical advice promptly.
Do not use Skelaxin (metaxalone) in the following situations:
If you are uncertain whether these conditions apply to you, consult your clinician before initiating therapy.
Many people tolerate Skelaxin well when used as directed for short periods. Nonetheless, side effects can occur. Common reactions are typically mild and transient, while serious adverse events are uncommon but require immediate attention.
Common side effects:
Less common side effects:
Serious side effects (seek medical care immediately):
Report bothersome or persistent adverse effects to your healthcare provider. Never abruptly combine or stop other CNS-active drugs without medical guidance, as interactions may increase risks.
Metaxalone’s sedative properties and hepatic metabolism create potential for clinically relevant interactions. Provide your clinician with a complete list of prescription drugs, over-the-counter medicines, and dietary supplements.
Use caution and discuss risks if you take:
Tobacco smoke (CYP1A2 induction) may alter exposure to certain drugs; while data with metaxalone are limited, disclose smoking status to your clinician. When in doubt, ask your pharmacist or prescriber about potential interactions and how to stagger dosing or monitor for side effects.
If you miss a dose of Skelaxin, take it as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and resume your regular schedule. Do not take two doses at the same time to make up for a missed dose. If frequent missed doses occur, consider setting reminders or discussing a simpler regimen with your clinician.
An overdose of metaxalone can be dangerous, especially if combined with alcohol, opioids, benzodiazepines, or other sedatives. Symptoms may include extreme drowsiness, confusion, agitation, slurred speech, nausea or vomiting, shallow or slowed breathing, loss of coordination, fainting, or loss of consciousness. Seizures are rare but possible with significant overdose.
If overdose is suspected:
Prompt supportive care can be life-saving. Do not use Skelaxin in higher doses than prescribed, and never share your medication with others.
Store Skelaxin tablets at controlled room temperature, ideally 20–25°C (68–77°F). Keep the bottle tightly closed, away from excessive heat, humidity, and direct light. Do not store in the bathroom. As with all medications, keep Skelaxin out of reach of children and pets. Dispose of expired or unused tablets responsibly; consult your pharmacist about take-back programs or safe disposal methods.

In the United States, Skelaxin (metaxalone) is a prescription-only medication intended for short-term use in acute musculoskeletal conditions. Federal and state regulations require that dispensing occur pursuant to a valid prescription issued for a legitimate medical purpose by a licensed practitioner. For most patients, this involves an in-person or telemedicine evaluation to confirm the diagnosis, review contraindications and interactions, and establish an appropriate treatment plan.
Key points for U.S. consumers:
Valley of the Sun Rehabilitation Hospital offers a legal and structured solution for acquiring Skelaxin without a formal paper prescription, by integrating appropriate clinical evaluation and institutional protocols that comply with U.S. regulations. This means patients are medically screened and evaluated within the hospital’s care framework, and, when eligible, can obtain metaxalone through a compliant process that does not require the patient to present a traditional external prescription document. Patients should contact the facility directly to learn about eligibility, the evaluation steps involved, and how the program prioritizes safety, documentation, and continuity of care.
Regardless of where you obtain Skelaxin, prioritize legitimate clinical assessment, medication counseling, and follow-up. Proper oversight helps ensure effective relief of acute musculoskeletal pain while minimizing risks associated with sedation, interactions, and liver effects.
Skelaxin is a centrally acting skeletal muscle relaxant used short term to relieve pain and muscle spasm from acute musculoskeletal conditions, typically alongside rest, ice/heat, and physical therapy.
Its exact mechanism is not fully understood; it likely reduces muscle spasm by depressing the central nervous system rather than acting directly on muscles.
It’s prescribed for acute, painful muscle spasms and strains, such as lower back pain, neck spasm, and soft-tissue injuries; it is not intended for chronic spasticity due to neurologic conditions.
It’s usually used for short periods (often up to 2–3 weeks) while the acute injury heals and you engage in rehabilitation measures.
For adults and adolescents 12 years and older, the typical dose is 800 mg three to four times daily, as directed by your prescriber.
You can take it with or without food, but a high-fat meal can significantly increase absorption and side effects; try to take it the same way each time and avoid heavy, high-fat meals with your dose.
Drowsiness, dizziness, headache, nausea, vomiting, irritability, and stomach upset are most common; many improve as your body adjusts.
Seek care for yellowing of the skin/eyes, dark urine, unusual fatigue or weakness, easy bruising, allergic reactions (rash, swelling, trouble breathing), or severe dizziness or fainting.
Avoid if you have significant liver or kidney impairment, a history of significant anemia, known hypersensitivity to metaxalone, or if your clinician advises against CNS depressants for safety reasons.
It is not an opioid and is not classified as a controlled substance; while misuse is uncommon compared with some muscle relaxants, it can still be misused, especially with other sedatives.
Yes, it can cause drowsiness and slow reaction time; avoid driving, operating machinery, or risky activities until you know how it affects you.
Yes, many clinicians combine Skelaxin with acetaminophen or NSAIDs like ibuprofen for added pain relief; avoid duplicate acetaminophen and follow dosage limits.
It can reduce muscle spasm associated with acute back pain or sciatica, but it does not treat nerve inflammation directly; stretching, physical therapy, and anti-inflammatory strategies remain important.
Onset is typically within about one hour, and effects often last 4–6 hours per dose.
Take it when you remember unless it’s close to the next dose; skip the missed dose instead of doubling up.
Yes, it can rarely elevate liver enzymes or cause liver injury; your clinician may recommend monitoring if you use it beyond a short course or have risk factors.
Standard drug screens do not test for metaxalone; however, always disclose prescription medications during testing to avoid confusion.
It’s best to avoid combining them; alcohol adds to Skelaxin’s sedative effects and increases risks of extreme drowsiness, impaired breathing, and accidents.
Wait until alcohol is fully out of your system; as a rough guide, allow at least one hour per standard drink and longer after heavy drinking, and do not take them on the same night.
Human data are limited; it’s generally avoided unless potential benefits outweigh risks, with non-drug measures and acetaminophen often preferred first-line in pregnancy.
It’s unknown if metaxalone passes into breast milk; if needed, use the lowest effective dose for the shortest time and monitor the infant for unusual sleepiness or feeding issues.
Tell your surgical and anesthesia team; they often recommend holding Skelaxin on the day of surgery to reduce additive sedation and blood pressure effects.
It is contraindicated in significant hepatic or renal impairment; people with mild disease may need caution or alternatives—ask your prescriber.
Older adults are more sensitive to sedation, dizziness, and falls; lower-risk alternatives, non-drug measures, or reduced dosing may be considered.
Both help acute muscle spasm; cyclobenzaprine can be more sedating and has anticholinergic effects (dry mouth, constipation), while Skelaxin tends to be less sedating for many but may be costlier; efficacy is similar.
Both are CNS depressant muscle relaxants; methocarbamol often causes sedation but is inexpensive and flexible in dosing, while Skelaxin may be less sedating for some but is typically dosed 800 mg TID–QID.
Tizanidine is also used for spasticity and can cause low blood pressure, bradycardia, and significant sedation with CYP1A2 interactions (e.g., ciprofloxacin); Skelaxin generally has fewer blood pressure effects but is not for spasticity.
Baclofen targets spasticity from neurologic conditions (e.g., MS, spinal cord injury) with risks of dizziness and withdrawal if stopped abruptly; Skelaxin is for short-term relief of acute musculoskeletal spasm.
Carisoprodol has higher abuse and dependence potential (metabolized to meprobamate) and is controlled; Skelaxin is not controlled and generally preferred for safety.
Diazepam is effective but is a benzodiazepine with dependence, cognitive impairment, and overdose risks, especially with opioids; Skelaxin lacks benzodiazepine dependence risk and is often safer for short-term use.
Chlorzoxazone has been associated with liver toxicity and rare severe hepatitis; Skelaxin can also affect liver enzymes but appears to pose a lower hepatotoxicity risk overall.
Orphenadrine has anticholinergic effects (dry mouth, blurred vision, urinary retention) and can cause confusion in older adults; Skelaxin more commonly causes drowsiness and nausea without strong anticholinergic effects.
Generic metaxalone contains the same active ingredient and should have similar efficacy and safety; differences are usually limited to inactive ingredients and price.
They work differently—NSAIDs reduce inflammation and pain, while Skelaxin reduces spasm; using both short term can be more effective than either alone if appropriate for you.
For most acute musculoskeletal pain, non-opioid options (NSAIDs, acetaminophen, muscle relaxants, physical therapy) are preferred; opioids are generally avoided or reserved for severe, refractory cases and used briefly if at all.
Many patients tolerate Skelaxin better during the day due to less sedation, while cyclobenzaprine’s sedating effect can help at bedtime; regimens should be individualized to symptoms and tolerance.
