Cyclobenzaprine is available in tablets of 5 and 10 mg in multiple generic forms and under the trade names of Flexeril, Flexamid and Amrix.

You are encouraged to report negative side effects of prescription drugs to the FDA. Cyclobenzaprine reduced or abolished skeletal muscle hyperactivity in several animal models. Animal studies indicate that cyclobenzaprine does not act at the neuromuscular junction or directly on skeletal muscle. Evidence suggests that the net effect of cyclobenzaprine is a reduction of tonic somatic motor activity, influencing both gamma (γ) and alpha (α) motor systems. The plasma concentration of cyclobenzaprine is increased in patients with hepatic impairment (see CLINICAL PHARMACOLOGY, Pharmacokinetics, Hepatic Impairment).

Flexeril (Cyclobenzaprine) is a muscle relaxant used, in combination with rest and physical therapy, to treat skeletal muscle conditions such as pain, injury or spasm. It can reduce the severity and frequency or spasms, and reduce pain by relaxing the muscles. Flexeril is a centrally acting muscle relaxant, which means it doesn’t directly affect the muscles. It exhibits its affects through the central nervous system by blocking signals from the brain that would normally cause the muscles to tense and spasm.
