Cyclobenzaprine is a muscle relaxant commonly prescribed to relieve muscle spasms and discomfort associated with acute musculoskeletal conditions. It works by acting on the central nervous system to help reduce muscle tension and improve mobility. Typically taken as a short-term treatment, cyclobenzaprine is often used alongside rest and physical therapy. It may cause side effects such as drowsiness, dry mouth, and dizziness, so patients are advised to avoid activities that require alertness until they know how the medication affects them.
