Label Comprehension

Though OTC and prescription drugs may gain approval through the same NDA process, there is one striking difference. The FDA sometimes requires sponsors of OTC drugs to conduct consumer studies, including label comprehension, self-selection, and actual use studies that are designed to evaluate proposed OTC drug product labeling.

A label comprehension study assesses the extent to which consumers understand the information on OTC drug product labeling and how well they apply this information when making drug product-use decisions in a hypothetical situation.

If you are considering the submission of an NDA for an OTC drug product, you should review, among other things, FDA's guidance document on label comprehension and self-selection studies on FDA's Web site, accessible here.
