What is Soma?

Soma (carisoprodol) is a skeletal muscle relaxant that is used to relax certain muscles in your body and relieve the stiffness, pain, and discomfort caused by strains, sprains, or other injury to your muscles. It is used with rest and physical therapy to treat acute, painful muscle conditions. Soma/Carisoprodol may also be used for purposes other than those listed.

Common names are Soma, Soma Carisoprodol, Carisoprodol and Carisprodel.

How does Soma work?

Soma works by blocking the nerve impulses (or pain sensations) that are sent to your brain through the Central Nervous System. Soma begins working in about 30 minutes and lasts for approximately 2?6 hours.
