Flexeril
® (
cyclobenzaprine hydrochloride) is a prescription muscle relaxant. It is meant to be used temporarily to treat muscle spasms due to injury or other muscle problems.
Brand-name Flexeril is made by McNeil Consumer & Specialty Pharmaceuticals.
Generic Flexeril is made by several different manufacturers.
It is not clear as to how exactly Flexeril works to relieve muscle spasms. However, it is known that it mostly works in the brain stem, not in the spinal cord and not directly on the muscles. The medication only works to relieve muscle spasms caused by problems in the muscles; it does not help with muscle spasms caused by problems in the brain or spinal cord.
