Carisoprodol Overview

Reviewed: May 24, 2013
Updated: 

Carisoprodol is a prescription medication used to relax muscles and relieve pain due to muscle spasms. Carisoprodol belongs to a class of drugs called muscle relaxants, which help prevent muscle spasms without affecting overall muscle control.

This medication comes in tablet form and is taken 3 times a day and at bedtime, with or without food. It is recommended that carisoprodol be taken for a maximum of 2 to 3 weeks.

Common side effects of carisoprodol include headache, nausea, and vomiting.

Carisoprodol can cause drowsiness and dizziness. Do not drive or operate machinery until you know how carisoprodol affects you. Alcohol may intensify this side effect.

Carisoprodol Genetic Information

CYP2C19 is an enzyme in the blood that is responsible for breaking down carisoprodol and other drugs in the body. Some patients have less of this protein in their bodies, affecting how much of the drug gets eliminated. Levels of CYP2C19 can vary greatly between individuals, and those having less of this protein are known as "poor metabolizers." 

CYP2C19 testing is done to determine whether you are a poor metabolizer. If you are a poor metabolizer, the levels of carisoprodol in your blood can become too high. As a result you may be at an increased risk of having more side effects from carisoprodol. Carisoprodol can lead to side effects such as drowsiness, dizziness, and headache, among others. (See Carisoprodol Side Effects and Precautions sections). 

Your doctor may adjust your dose of carisoprodol if you are a poor metabolizer.
