OBJECTIVES: This study aimed to describe the use of over-the-counter (OTC) drugs and to identify predictors for their use in the elderly living alone. METHODS: This is a cross-sectional study that enrolled 1,099 subjects. Data regarding socio-demographic status, medical condition, cognition, mood disorder and use of OTC drugs were collected using self-administered questionnaire and from a specific semi-structured interview by a trained nurse. Data regarding use of OTC drugs were analyzed using descriptive statistics. Logistic regression analysis was applied to examine factors associated with the use of OTC drugs. RESULTS: The use of OTC drugs were reported by 35.4% of the subjects. Analgesics (13.6%) was the most frequent drugs. Depression (OR=1.10, 95% CI=1.10–1.87) and comorbidities measured by cumulative illness rating scale (CIRS) (OR=1.08, 95% CI=1.03–1.12) were significantly associated with the use of OTC drugs in the elderly living alone. CONCLUSIONS: Depression and severity of underlying medical conditions could be a predictor of the use of OTC drugs in the elderly living alone. The clinicians should be vigilant regarding the potential use of nonprescription medications in the elderly.
