Carisoprodol is a prescription muscle relaxant used to treat acute musculoskeletal pain and discomfort. It works by blocking pain sensations between the nerves and the brain. As a Schedule IV controlled substance in the U.S., it carries significant risks of misuse, dependence, and side effects like drowsiness and dizziness. It is intended only for short-term use (up to 2-3 weeks) under strict medical supervision and is not suitable for individuals with a history of substance abuse or certain medical conditions.
