What Is Flexeril 5mg?

Flexeril 5mg is the brand name for cyclobenzaprine hydrochloride 5mg, a prescription skeletal muscle relaxant used for the short-term treatment of painful muscle spasms associated with acute musculoskeletal conditions such as strains, sprains, and injuries. It is generally prescribed alongside rest, physical therapy, and other supportive treatments, rather than as a standalone therapy.

Cyclobenzaprine works on the central nervous system (CNS) to reduce muscle spasms and improve comfort. It is not intended for long-term use and is typically prescribed for up to two or three weeks, as there is limited evidence supporting longer treatment durations for acute muscle conditions.

How Flexeril 5mg Works

Flexeril belongs to the skeletal muscle relaxant class of medications. Unlike pain relievers that act directly on injured tissues, cyclobenzaprine works primarily in the brain and brainstem to reduce the nerve signals responsible for muscle spasms.

Its effects may help:

• Reduce painful muscle spasms

• Relieve muscle stiffness

• Improve range of motion

• Decrease discomfort caused by strains or sprains

• Support recovery when combined with rest and physical therapy
