Prescribed medication use among troops deploying to Somalia: pharmacoepidemiologic analysis.

To describe the frequency of chronic ambulatory prescriptions dispensed to troops, pharmacists analyzed records of soldiers deploying to Somalia for Operation Restore Hope. Prescriptions recorded in the Fort Drum pharmacy data base for soldiers deploying between November 24, 1992, and January 12, 1993, were compared to the roster of troops deployed. Among 3,701 deploying soldiers, 273 patients (7.4%) received 425 prescriptions. For each 1,000 troops, 114.8 prescriptions were dispensed. Of 333 presumptive diagnoses, the most common diagnostic groups were contraceptive, musculoskeletal, dermatologic, respiratory, and cardiovascular. Of 425 prescriptions, the most common therapeutic classes of medication dispensed were oral contraceptives, anti-inflammatory drugs, acne treatments, and beta-adrenergic agonists. Generically, the common prescribed substances were contraceptives, ibuprofen, pirbuterol, temazepam, piroxicam, and beclomethasone. Although women represented 6.8% of troops, women represented 31.5% of prescription recipients and received 29.4% of prescriptions. Women were 6.5 times as likely to receive a prescription as men (p < 0.0001); this relative risk was 3.4 if contraceptives were omitted from analysis (p < 0.0001). Two hospitalizations in Somalia may have been related to medication use.
