Cyclobenzaprine is a prescription muscle relaxant used to relieve muscle spasms, stiffness, and tightness caused by strains, sprains, or injuries. It works on the central nervous system to calm overactive muscle signals, helping your body relax so you can move more comfortably. Most people use it short-term, along with rest and gentle physical therapy, to improve mobility, reduce pain, and even sleep better when muscle spasms are keeping them up at night.
