Use of psychotropic medications before and after Sept. 11, 2001

This study examined patterns of psychotropic medication use after the Sept. 11, 2001, terrorist attacks.

It drew from two large pharmacy data sets, one providing nationally representative aggregate projections for all U.S. prescriptions (156.9 million claims for psychotropic medications during the study period) and a second from the nation's largest pharmacy benefit management organization (36.4 million enrollees per month), 4.1% of whom had a prescription for a psychotropic medication during the study period. Analyses examined use of antidepressant, antipsychotic, anxiolytic, and hypnotic medications in the 12 weeks before and after Sept. 11, 2001, compared with the same weeks during 2000.

Nationally and in Washington, D.C., there was no evidence of an increase in overall prescriptions, new prescriptions, or daily doses for psychotropic medications. In New York City, there was an increase in the proportion of existing users with psychotropic dose increases in the weeks after the attacks (16.9% in 2001 versus 13.6% in 2000) but no significant increase in the rate of new psychotropic prescriptions.

For most of the nation, the distress associated with the terrorist attacks was not accompanied by a commensurate increase in the use of psychotropic medications. In New York City, there was a statistically significant but modest increase in the proportion of individuals with dose increases in their psychotropic medications.
