Multicenter Study
Improving prescription drug warnings to promote patient comprehension.
Prior studies have documented a high prevalence of patients who misunderstand prescription drug warning labels, placing them at risk for medication error. We evaluated whether the use of "enhanced print" drug warnings could improve patient comprehension beyond a current standard. ⋯ Simple, explicit language on warning labels can increase patient understanding; the addition of appropriate icons is particularly useful for adults with lower literacy skills. Evidence-based standards are needed to promote patient-centered prescription labeling practices.
