DescriptionA centrally acting skeletal muscle relaxant whose mechanism of action is not completely understood but may be related to its sedative actions. It is used as an adjunct in the symptomatic treatment of musculoskeletal conditions associated with painful muscle spasm. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1202)

Toxicity Profile
Route of ExposureOral
Mechanism of ToxicityCarisoprodol is a central nervous system depressant that acts as a sedative and skeletal muscle relaxant. Rather than acting directly on skeletal muscle, carisoprodol interrupts neuronal communication within the reticular formation and spinal cord, resulting in sedation and alteration in pain perception. Its exact mechanism of action is not yet known.
MetabolismHepatic. Metabolized in the liver via the cytochrome P450 oxidase isozyme CYP2C19. Route of Elimination: Carisoprodol is eliminated by both renal and non-renal routes. Half Life: 8 hours
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesFor the relief of discomfort associated with acute, painful, musculoskeletal conditions.
Minimum Risk LevelNot Available
Health EffectsNot Available
SymptomsSymptoms of overdose include drowsiness, giddiness, nausea, indigestion, or rash. Other adverse effects attributed to therapeutic use of carisoprodol include dizziness, irritability, insomnia, diplopia, temporary loss of vision, ataxia, weakness, headache, and dysarthria. Non-CNS adverse effects include gastrointestinal complaints, tachycardia, and postural hypotension. Patients sensitive to sulfites or tartrazine may experience wheezing, allergic rashes including erythema multiforme, or anaphylaxis after using some preparations of carisoprodol which contain such additives
