Pharmacy Author:
Medical and Pharmacy Editor:

Carisoprodol is not a controlled substance. Patients may become dependent on carisoprodol and discontinuation after long-term use may cause withdrawal symptoms.

PRESCRIPTION: Yes

GENERIC AVAILABLE: Yes

PREPARATIONS: Tablets: 250 and 350 mg.

STORAGE: Tablets should be stored between 15-30 C (59-86 F).

DOSING: The recommended dose of carisoprodol is 250 or 350 mg three times daily and at bedtime.

DRUG INTERACTIONS: Carisoprodol interacts with other medications and drugs that slow the brain's processes, such as alcohol, barbiturates, benzodiazepines (for example, lorazepam [Ativan]), and narcotics, accentuating their effects and causing drowsiness.

Omeprazole (Prilosec) and fluvoxamine (Luvox) may reduce the elimination of carisoprodol, leading to increased side effects.

St John's Wort and rifampin (Rifadin) increase the elimination of carisoprodol, possibly resulting in a reduced effect.

PREGNANCY: There are no adequate studies of carisoprodol in pregnant women.

NURSING MOTHERS: Carisoprodol accumulates in breast milk in concentrations twice those of the mother's blood. The effects of carisoprodol on the infants of lactating mothers are unknown. Therefore, caution should be used when using carisoprodol in women who are breastfeeding.
