Flexeril (Cyclobenzaprine) – Uses, Benefits, Safety Information & Medication Guide

Flexeril is the brand name for cyclobenzaprine, a prescription muscle relaxant used for the short-term relief of muscle spasms and discomfort associated with acute musculoskeletal conditions. It is commonly prescribed along with rest, physical therapy, and other supportive treatments to help improve recovery from muscle injuries.

Cyclobenzaprine works by acting on the central nervous system to reduce excessive nerve activity involved in muscle spasms. It does not directly relax skeletal muscles but helps decrease the sensation of muscle tightness and discomfort.

Because Flexeril may cause drowsiness and affects the nervous system, it should be used only as directed by a qualified healthcare professional.

How Flexeril Works

Cyclobenzaprine works primarily within the brain and spinal cord by reducing certain nerve signals responsible for muscle spasms.

Its effects may help:

Flexeril does not treat the underlying cause of an injury but may help manage associated muscle symptoms.
