Quality of Instructions on Prescription Drug Labels: Effects on Memory and Comprehension in Young and Old Adults

Abstract

We examined both comprehension of and memory for information on prescription labels as a function of age, memory load, and study time across three experiments with young and old adults. We found that older adults consistently manifested poorer recall of prescription information than young adults; age effects occurred even when participants received unlimited study time; and both young and old adults had substantial difficulty comprehending drug information as it is presented from a pharmacy.
