Find the Best Muscle Relaxant for Your Situation
Answer a few questions about your pain and health to get personalized recommendations on which muscle relaxant might work best for you.
When you're stuck with a bad muscle spasm-say, from a pulled back or a sudden injury-you don’t just want relief. You want relief that works, without side effects that leave you groggy, dizzy, or worse. Skelaxin (metaxalone) is one of the most commonly prescribed muscle relaxants in the UK and US, but it’s not the only option. Many people wonder: is Skelaxin really the best choice? Or are there safer, more effective alternatives out there?
What is Skelaxin (Metaxalone)?
Skelaxin is the brand name for metaxalone, a centrally acting muscle relaxant used short-term to relieve discomfort from acute, painful musculoskeletal conditions. It was first approved in the 1960s and works by calming overactive nerve signals in the brain and spinal cord that cause muscle stiffness and spasms.
Unlike some older muscle relaxants, Skelaxin doesn’t directly act on the muscles themselves. Instead, it reduces the intensity of pain signals traveling to the brain. That’s why it’s often paired with rest, physical therapy, or ice/heat treatment-not as a standalone fix.
Typical doses are 800 mg taken three to four times daily. Most people start feeling relief within an hour. But here’s the catch: while it’s less sedating than some alternatives, about 1 in 5 users still report drowsiness, dizziness, or nausea. For older adults or those on multiple medications, that’s a real concern.
Why Look for Alternatives?
Not everyone tolerates Skelaxin well. Some find the side effects too strong. Others need something that works faster, lasts longer, or doesn’t interfere with their other prescriptions. And then there are people who’d rather avoid prescription drugs altogether if possible.
Also, Skelaxin isn’t approved for long-term use. If your muscle pain sticks around beyond a few weeks, your doctor will likely shift focus to physical therapy, stretching, or other non-drug treatments. But in the short term, you need something that helps you move again-without knocking you out.
That’s where alternatives come in. Let’s compare the most common ones, based on real-world use, side effect profiles, and how they stack up against Skelaxin.
Alternative 1: Cyclobenzaprine (Flexeril)
Cyclobenzaprine is one of the most widely prescribed muscle relaxants in the UK and US. It’s sold under brand names like Flexeril and Amrix, and also comes in extended-release form.
Like Skelaxin, cyclobenzaprine works on the central nervous system. But it’s more likely to cause drowsiness-up to 30% of users report feeling sleepy, even at normal doses. That makes it a poor choice for people who drive, operate machinery, or work night shifts.
It’s also metabolized by the liver, so it can interact with antidepressants, alcohol, or sleep aids. If you’re on sertraline or fluoxetine, your doctor might avoid cyclobenzaprine entirely.
Compared to Skelaxin: cyclobenzaprine works faster but has a higher risk of sedation. Skelaxin is better for people who need to stay alert during the day.
Alternative 2: Methocarbamol (Robaxin)
Methocarbamol (brand name Robaxin) is another common option. It’s been around since the 1950s and is often used in hospital settings for acute back pain or after surgery.
Methocarbamol has a lower risk of addiction than some alternatives, and it’s generally well-tolerated. But it can cause dizziness, blurred vision, and sometimes a metallic taste in the mouth-which some people find unpleasant.
It’s also cleared by the kidneys, so it’s not ideal for people with kidney disease. Dosing is usually 1,500 mg every 6 to 8 hours, which means taking pills more often than Skelaxin.
Compared to Skelaxin: methocarbamol is slightly less effective for chronic muscle tension but may be better for short-term trauma recovery. It’s also cheaper, since it’s been generic for decades.
Alternative 3: Tizanidine (Zanaflex)
Tizanidine (Zanaflex) is a different kind of muscle relaxant. It works by activating alpha-2 receptors in the spinal cord, which reduces nerve signals that cause muscle stiffness.
This makes it especially useful for people with neurological conditions like multiple sclerosis or spinal cord injuries. But it’s also used for severe back spasms.
Its biggest downside? It can cause a sudden drop in blood pressure, leading to dizziness or fainting. It also causes dry mouth and fatigue. Many users report feeling "zoned out" for hours after taking it.
It’s short-acting-effects last only 3 to 6 hours-so you need to take it 3 to 4 times a day. It also interacts with other medications that affect the liver, like fluvoxamine or ciprofloxacin.
Compared to Skelaxin: tizanidine is stronger and better for neurological-related spasticity, but far more sedating. Skelaxin is a gentler option for everyday muscle pain.
Alternative 4: Baclofen
Baclofen is primarily used for spasticity caused by conditions like cerebral palsy, stroke, or multiple sclerosis. But it’s also prescribed off-label for chronic back pain.
It works by mimicking a natural brain chemical (GABA) that calms nerve activity. It’s effective for deep, persistent muscle tightness. But it’s not great for sudden, sharp spasms.
Side effects include weakness, drowsiness, and sometimes confusion-especially in older adults. Stopping baclofen suddenly can cause hallucinations or seizures, so it must be tapered off carefully.
It’s also available as a spinal pump for severe cases, but that’s only for hospital-managed treatment.
Compared to Skelaxin: baclofen is more targeted for long-term neurological muscle issues. Skelaxin is better for short-term, non-neurological muscle pain.
Alternative 5: Non-Prescription Options
Not everyone wants a prescription. For mild to moderate muscle pain, over-the-counter (OTC) options can be surprisingly effective.
- NSAIDs like ibuprofen (Advil) or naproxen (Aleve) reduce inflammation and pain. They’re often the first line of defense for muscle strains.
- Topical creams with menthol, camphor, or capsaicin can numb the area and improve blood flow. Many people find them helpful for localized pain.
- Heat wraps and cold packs aren’t drugs, but they’re backed by solid evidence for reducing spasm-related pain.
- Physical therapy and stretching routines-especially for the lower back-can prevent recurring spasms better than any pill.
These options won’t replace Skelaxin for severe spasms, but they’re safer for long-term use and have fewer interactions. Many doctors now recommend combining them with a short course of muscle relaxants, if needed.
Which One Should You Choose?
There’s no single "best" muscle relaxant. The right choice depends on your health, your lifestyle, and what’s causing the pain.
Here’s a quick guide:
- Choose Skelaxin if you need daytime relief without heavy drowsiness, have no liver issues, and are taking few other medications.
- Choose cyclobenzaprine if you can afford to be sedated and need strong, fast relief-maybe for a night or two after surgery.
- Choose methocarbamol if cost matters and you’re dealing with a recent injury.
- Choose tizanidine if you have nerve-related spasticity and your doctor has ruled out low blood pressure risks.
- Choose baclofen only if you have a neurological condition causing muscle stiffness.
- Try OTC options first if your pain is mild or you’re trying to avoid prescriptions.
Also, remember: muscle relaxants are meant for short-term use-usually no longer than 2 to 3 weeks. If pain lasts longer, it’s a sign something else is going on. Maybe you need imaging, a referral to a physiotherapist, or a change in posture or activity.
What to Avoid
Some muscle relaxants are rarely used today because of safety issues:
- Carisoprodol (Soma) is metabolized into a controlled substance (meprobamate), which can be addictive. It’s been banned in several countries and is no longer recommended in the UK.
- Diazepam (Valium) is a benzodiazepine. While it can relax muscles, it carries high risks of dependence, memory loss, and falls in older adults. It’s not a first-line muscle relaxant anymore.
Stick to the options listed above. Avoid anything that feels "too strong" or promises miracle results. Muscle pain rarely needs a chemical sledgehammer.
Final Thoughts
Skelaxin isn’t perfect, but for many people, it’s the right balance of effectiveness and tolerability. If you’ve tried it and it didn’t work-or if side effects were too much-don’t assume you’re out of options. There are other pills, and there are non-drug solutions that work just as well, if not better.
The goal isn’t to find the strongest muscle relaxant. It’s to find the one that lets you move without making you feel worse. Talk to your doctor about your daily routine, your other meds, and what kind of relief you actually need. Sometimes, the best treatment isn’t a pill at all-it’s a stretching routine, a heat pad, or a visit to a physiotherapist.
Is Skelaxin stronger than cyclobenzaprine?
Not necessarily. Cyclobenzaprine tends to have a stronger sedative effect, which can make it feel more powerful. But Skelaxin is just as effective at reducing muscle spasms for most people, with fewer side effects like drowsiness. It’s not about strength-it’s about how well you tolerate it.
Can I take Skelaxin with ibuprofen?
Yes, many doctors recommend combining Skelaxin with ibuprofen or naproxen. Skelaxin targets nerve signals, while NSAIDs reduce inflammation. Together, they often work better than either alone. Just avoid alcohol and check with your pharmacist if you’re on other meds.
How long does Skelaxin stay in your system?
Skelaxin has a half-life of about 3 to 4 hours, meaning most of it leaves your body within 12 to 24 hours. But its effects wear off faster-usually within 6 to 8 hours. That’s why it’s taken multiple times a day.
Is there a natural alternative to Skelaxin?
There’s no natural substance that works exactly like Skelaxin, but magnesium supplements, tart cherry juice, and massage therapy can help reduce muscle tension. Stretching and heat therapy are often more effective long-term solutions than any supplement.
Can Skelaxin cause weight gain?
Weight gain isn’t a common side effect of Skelaxin. But if you’re less active due to drowsiness or pain, you might gain weight indirectly. The drug itself doesn’t affect metabolism or appetite.
What happens if I stop Skelaxin suddenly?
Unlike some muscle relaxants, Skelaxin doesn’t cause physical dependence. You can stop it without tapering. But if your pain returns, it’s a sign the underlying issue hasn’t resolved. Don’t assume the problem is gone just because the drug wore off.
Next Steps
If you’re currently taking Skelaxin and it’s working well, keep doing what you’re doing. But if you’re frustrated with side effects or it’s not helping, talk to your doctor. Bring a list of what you’ve tried-even OTC options. They might suggest switching to methocarbamol, adding physical therapy, or trying a topical cream.
And if you’ve never tried non-drug treatments, now’s the time. A 10-minute daily stretch routine, a heating pad before bed, or a session with a physiotherapist might do more for your back than another prescription.
Remember: muscle spasms are a symptom, not a disease. The goal isn’t just to numb the pain-it’s to get your body moving again, safely and sustainably.
