Summary: Results of a study of associations between visual acuity and the risk of misuse of OTC acetaminophen products in a sample of community-dwelling adults are reported. Among the study participants (n = 500), 39% had limited literacy and 54% were categorized as having low vision. After controlling for age, race, and prior acetaminophen use, low vision was independently associated with an increased risk of self-dosing errors and misunderstanding of concomitant-use risks.
