Abstract

Among US community dwelling individuals aged ≥65 years, about as many persons take nonprescription drugs as take prescription drugs. A review of US data from the last 2 decades indicates that the average number of over-the-counter (OTC) drugs taken daily is around 1.8, but varies with geographical area (highest in the Midwest) and race/ethnicity (lowest use among Hispanics, followed by African Americans, and highest use among Whites). Use has consistently been found to be higher in women than in men. While OTC use appears to be increasing over time, it also decreases with increase in age. The most common OTC classes used are analgesics, laxatives and nutritional supplements. Our ability to explain or to predict OTC use and change in use is poor, and further studies, particularly on use by elderly individuals of minority races, are needed.
