Carisoprodol: an unrecognized drug of abuse

Abstract

During a 6-month monitoring period, carisoprodol was detected in the urine specimens of 19 patients for whom drug screening had been ordered for purposes of patient care. The clinical history suggested that in 7 cases the drug was abused or implicated in a suicide attempt or gesture. In another 7 cases, the drug was used primarily for medical purposes, and in 5 cases the reason for use could not be determined. One patient ingested homemade tablets that were found to contain carisoprodol. In an additional case, the drug was detected in breast milk. Physical findings, clinical history, and treatment are described, and the profile of a typical carisoprodol user is discussed. It seems that carisoprodol has become an unrecognized drug of abuse, at least in our community. This drug and its metabolite, meprobamate, should be included in comprehensive drug screening.
