title: Alprazolam abuse in Texas, 1998-2004.
abstract: Alprazolam (Xanax) is used in the treatment of anxiety, depression, and panic attacks, and is subject to abuse. The objective of this study was to describe the patterns of alprazolam abuse and drug identification (ID) calls received by several poison control centers. Cases were alprazolam calls received by 6 poison control centers during 1998-2004. Of 25,954 alprazolam calls received, 42% were drug ID calls and 51% were human exposure calls, of which 18% were abuse calls. The number of drug ID calls and the number of abuse calls both increased during the 7-yr period. Male patients accounted for 54% of abuse calls and females for 66% of nonabuse calls. Adolescent patients comprised 43% of abuse calls but only 12% of nonabuse calls. Although the majority of both types of human exposures occurred at the patient's own residence, abuse exposures were more likely than other exposures to occur at school (9% vs. 1%) and public areas (6% vs. 1%). While abuse calls were less likely than nonabuse calls to have no adverse clinical effects (19% vs. 23%), they were more likely to have minor medical outcomes (60% vs. 50%). Alprazolam abuse in Texas appears to be increasing. Alprazolam abusers are more likely to be male and often adolescent. Alprazolam abuse as compared to other exposures is more likely to occur outside of the person's home. Alprazolam abuse is more likely to involve some sort of adverse medical outcome.
