Looking for a tizanidine (Zanaflex) coupon? Tizanidine is a low-cost generic skeletal muscle relaxant, but the cash price can still vary a lot from one pharmacy to the next, so comparing before you fill is what saves you money. Rx.com checks tizanidine prices across more than 60,000 U.S. pharmacies and gives you a free discount coupon you can use with or without insurance. Enter your ZIP above to see today's price near you.
What is tizanidine and how does it work?
Tizanidine is a centrally acting alpha-2 adrenergic agonist, a type of skeletal muscle relaxant. It works in the brain and spinal cord to reduce nerve signals that cause muscles to tighten, easing muscle spasm, cramping, and tightness. It is the generic form of the brand Zanaflex.
Tizanidine is FDA-approved for the management of spasticity, such as the muscle tightness caused by multiple sclerosis or spinal cord injury. Because its effect is short-acting, doctors often reserve it for the activities and times of day when relief of spasticity matters most. It comes as both tablets and capsules; note that the two are not always bioequivalent because food changes how the drug is absorbed, so follow your prescriber's directions about taking it consistently with or without food.
How much does tizanidine cost, and how can a coupon help?
Tizanidine is available as an FDA-approved generic, so it is already one of the more affordable muscle relaxants. Even so, the cash price without insurance is not the same everywhere. Independent and chain pharmacies set their own prices, and the difference between two stores in the same town can be significant. That is exactly why comparing pays off.
Rx.com compares tizanidine prices across more than 60,000 pharmacies and provides a free coupon that can lower your out-of-pocket cost, whether or not you use insurance. There is no manufacturer copay savings card for generic tizanidine. To see the current price and the coupon for the strength and quantity you were prescribed, enter your ZIP above.
Tizanidine vs. other muscle relaxants
Tizanidine is one of several muscle relaxants, and the right choice depends on your condition and how you tolerate side effects. It tends to be shorter-acting and can cause noticeable drowsiness and lowered blood pressure. Related options your prescriber might consider include:
- Cyclobenzaprine (generic Flexeril) — commonly used for short-term muscle spasm from acute pain.
- Baclofen — another option used for spasticity, including from MS or spinal cord injury.
- Methocarbamol — used for muscle spasm relief.
- Metaxalone — often chosen when a less-sedating option is preferred.
All of these are available as generics. Only your prescriber can decide which fits your situation, so use this as a starting point for a conversation, not medical advice.
Tizanidine safety and important warnings
Tizanidine has no boxed warning, but there are important cautions. It commonly causes marked sedation, low blood pressure, and slowed heart rate, especially when the dose is increased, so use care with driving until you know how it affects you. Do not exceed 36 mg per day (three doses), and your provider may monitor your liver function because tizanidine can affect the liver. Do not stop high or long-term doses abruptly, as this can cause rebound high blood pressure and rapid heart rate; your prescriber will taper you off.
Tizanidine is contraindicated with the strong CYP1A2 inhibitors fluvoxamine and ciprofloxacin, which can raise tizanidine levels sharply and cause dangerously low blood pressure. It can add to the sedating effects of alcohol, opioids, and other sedatives, and may cause dose-related QT prolongation or, rarely, hallucinations. Use extra caution in older adults and in people with kidney problems. This is a summary, not a complete list; always review your full medication list and health history with your doctor or pharmacist.
