Self-medication in older adults can be problematic, especially if remedies taken without prescription interact with prescribed medications or if they produce adverse effects. Before designing interventions to improve self-medication, it is important to characterize patterns of self-medicating in local populations. This can be easily achieved through the conduct of simple surveys. ⋯ Self-medication in older adults is a problem that should be carefully addressed in public health policies. Surveys such as the present one are easy to carry out (and could conveniently be conducted in primary care settings), rapidly yield information about the true nature of self-medication in local populations, and provide a basis on which to design future interventions. Factors associated with self-medication in this study, including both socioeconomic characteristics (e.g. most self-medicators were poorly educated or lived alone) and therapeutic considerations (e.g. substantial proportions of patients self-medicated for hypertension, used previous prescriptions as the basis for self-medication, or reported adverse effects of self-medication), are vital clues to the design of effective and appropriately targeted interventions in the future.
