Alternatives to Metaxalone If You Can't Fill Your Prescription

You've been prescribed Metaxalone (Skelaxin) for muscle pain, but your pharmacy doesn't have it — or your insurance won't cover it. Before you give up on getting relief, it's worth knowing that several well-studied alternatives exist. Your doctor may be able to prescribe a different muscle relaxant that's equally effective and easier to find or afford.

Important: Never switch prescription medications without consulting your doctor. Different muscle relaxants work differently, have different side effects, and interact differently with other medications. This guide is meant to help you have an informed conversation with your healthcare provider — not to make a change on your own.

Why Metaxalone Might Not Be Available or Affordable

Metaxalone is generally available — it's not on the FDA's shortage list. But some patients face barriers including insurance coverage gaps, prior authorization requirements, or the high retail cash price ($109–$184 for 30 tablets without a coupon). Read our full breakdown in Why Is Metaxalone So Hard to Find? if you want more details on the access issues.

How Metaxalone Works (And Why It Matters for Alternatives)

Metaxalone is a centrally acting skeletal muscle relaxant. It works by depressing activity in the central nervous system, which leads to muscle relaxation. It does NOT directly relax muscles at the muscle fiber level. Importantly, Metaxalone is widely cited as the least sedating muscle relaxant in its class — a key advantage for patients who need to stay alert during the day.

When looking for alternatives, your doctor will weigh factors like sedation level, cost, drug interactions, and your specific condition.

Alternative 1: Cyclobenzaprine (Flexeril)

Cyclobenzaprine is the most commonly prescribed muscle relaxant in the United States. It's structurally related to tricyclic antidepressants and works centrally to reduce muscle spasm.

Typical dose: 5–10 mg three times daily (immediate-release); 15–30 mg once daily (extended-release)

Pros: Very affordable (as low as $4–$9 for 30 tablets with a GoodRx coupon); widely available; not a controlled substance

Cons: More sedating than Metaxalone; anticholinergic side effects (dry mouth, constipation); not recommended for patients with heart rhythm problems or those taking MAO inhibitors

Best for: Patients who can tolerate sedation (or who want a sedating effect at night) and need an affordable option

Alternative 2: Methocarbamol (Robaxin)

Methocarbamol is another centrally acting muscle relaxant. It's considered moderately sedating — less than cyclobenzaprine but slightly more than Metaxalone for many patients.

Typical dose: 1,500 mg four times daily for the first 48–72 hours, then 750–1,000 mg three to four times daily

Pros: Very affordable ($8–$30 for 30 tablets with or without a coupon); good safety profile; not a controlled substance

Cons: More pills per day than Metaxalone; may cause dizziness and drowsiness; urine may turn brown, black, or green (harmless but alarming)

Best for: Patients looking for a low-cost, well-tolerated alternative; also commonly used in elderly patients (unlike cyclobenzaprine, it's not on the Beers Criteria)

Alternative 3: Tizanidine (Zanaflex)

Tizanidine works differently from the others. It's an alpha-2 adrenergic agonist that reduces excitatory signals in the spinal cord, making it particularly useful for muscle spasticity rather than just spasm.

Typical dose: 2–4 mg every 6–8 hours as needed; short-acting

Pros: Flexible dosing; useful for spasticity from neurological conditions; not a controlled substance

Cons: Requires liver function monitoring; significant interaction with fluvoxamine and ciprofloxacin (contraindicated); can cause significant sedation and low blood pressure; short duration means more frequent dosing

Best for: Patients with spasticity from neurological conditions or those who need flexible, as-needed dosing

Alternative 4: Baclofen

Baclofen is a GABA-B receptor agonist that reduces muscle spasticity by inhibiting nerve activity in the spinal cord. It's most commonly used for spasticity related to neurological conditions like multiple sclerosis or spinal cord injury, but doctors also prescribe it for general muscle spasm.

Typical dose: 5 mg three times daily initially, titrated up to 20–40 mg three times daily

Pros: Very effective for spasticity; affordable generic; not a controlled substance

Cons: Must be tapered slowly — abrupt withdrawal can cause seizures; more appropriate for chronic conditions than short-term muscle spasm; sedating

Best for: Patients with spasticity from neurological conditions who haven't responded to other muscle relaxants

Before Switching: Try to Find Metaxalone First

If your issue is that your pharmacy is out of stock, you may not need to switch medications at all. medfinder calls pharmacies near you to find which ones currently have Metaxalone in stock, then texts you the results. It's worth trying before going through the process of getting a new prescription for an alternative.
