No, Cyclobenzaprine is not available over the counter in the United States, and you need a prescription from a licensed medical doctor to get it.
Cyclobenzaprine (also called Flexeril, Fexmid, and Amrix) is a muscle relaxant that helps relieve muscle spasms. Cyclobenzaprine can also help reduce pain from an injury if used alongside rest and physical therapy.
One of the benefits of cyclobenzaprine is that it is not a narcotic. Unlike other medications for muscle pain, cyclobenzaprine comes with a lower risk of abuse or addiction, allowing users to take it in addition to pain relief medication when recovering from an injury. Cyclobenzaprine should be used for no more than 2–3 weeks at a time.
