Flexeril (Cyclobenzaprine) – Uses, Dosage, Side Effects & Muscle Spasm Treatment
What Is Flexeril?
Flexeril is a prescription skeletal muscle relaxant used to relieve muscle spasms associated with acute musculoskeletal conditions, including strains, sprains, and injuries.
The active ingredient in Flexeril is cyclobenzaprine hydrochloride, which works by acting on the central nervous system (CNS) to reduce muscle spasms and improve mobility.
Flexeril was originally developed and marketed by McNeil Consumer & Specialty Pharmaceuticals, a subsidiary of Johnson & Johnson. Generic cyclobenzaprine is now manufactured by multiple pharmaceutical companies worldwide.
Flexeril and its generic equivalents are approved by the U.S. Food and Drug Administration for short-term treatment of muscle spasms associated with musculoskeletal conditions.

How Flexeril Works
Cyclobenzaprine works primarily in the brainstem and central nervous system, where it helps reduce signals that cause muscle spasms.
Unlike some muscle relaxants that act directly on muscles, Flexeril works centrally to:
-
Reduce muscle hyperactivity
-
Relieve painful spasms

Improve mobility during recovery from injury
Research from the National Institutes of Health indicates that cyclobenzaprine is most effective when used alongside rest and physical therapy.
