Carisoprodol, sold under the brand name Soma among others, is a medication used for musculoskeletal pain.[6] Effects generally begin within half an hour and last for up to six hours.[6] It is taken orally (by mouth).[6]

Common side effects include headache, dizziness, and sleepiness.[6] Serious side effect may include addiction, allergic reactions, and seizures.[6] In people with a sulfa allergy certain formulations may result in problems.[6] Safety during pregnancy and breastfeeding is not clear.[6][7] How it works is not clear.[6] Some of its effects are believed to occur following being converted into meprobamate.[6]

Carisoprodol was approved for medical use in the United States in 1959.[6] Its approval in the European Union was withdrawn in 2008.[8] It is available as a generic medication.[6] In 2019, it was the 343rd most commonly prescribed medication in the United States, with more than 800 thousand prescriptions.[9] In the United States, it is a Schedule IV controlled substance.[6]
