Used primarily as a muscle relaxant to treat skeletal muscle spasms and discomfort associated with acute, painful musculoskeletal conditions. It is typically prescribed alongside rest and physical therapy to relieve muscle tightness and spasms, improving mobility and reducing pain. Works by acting on the central nervous system to reduce muscle hyperactivity, rather than directly on the muscles themselves. Often used short-term, usually for two to three weeks, due to limited evidence of effectiveness beyond that period. May also help improve sleep and reduce pain in some patients due to its structural similarity to certain tricyclic antidepressants, though it is not approved for treating depression.
