FDA: Label Comprehension Studies for Nonprescription Drug Products

04.08.2010
The Food and Drug Administration (FDA) sometimes requires sponsors to conduct label comprehension studies that are designed to evaluate proposed nonprescription drug product labeling. This guidance is intended to provide recommendations to industry on conducting label comprehension studies. A label comprehension study assesses the extent to which consumers understand the information on nonprescription drug product labeling and then apply this information when making drug product use decisions in a hypothetical situation. Data derived from a label comprehension study can identify areas on the label that would benefit from clearer or simpler presentation of important consumer information.
