Pediculicide Drug Products

The FDA oversees OTC lice treatments, known as pediculicide drug products, through a specific monograph designated as M031. This monograph outlines the criteria that manufacturers must follow to ensure their products are safe and effective for treating head, pubic, and body lice. M031 dictates acceptable ingredients, proper labeling with directions and warnings, and manufacturing standards. Following this monograph allows lice treatments to be sold over-the-counter without a prescription. Examples of common monograph-approved ingredients include pyrethrins, which kill lice and their eggs. If a lice treatment contains unapproved ingredients or deviates from the monograph requirements, it would be classified as a new drug.
