Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a prescription from a healthcare professional, as compared to prescription drugs, which may be sold only to consumers possessing a valid prescription. In many countries, OTC drugs are selected by a regulatory agency to ensure that they are ingredients that are safe and effective when used without a physician’s care. OTC drugs are usually regulated by active pharmaceutical ingredients (APIs), not final products. By regulating APIs instead of specific drug formulations, governments allow manufacturers freedom to formulate ingredients, or combinations of ingredients, into proprietary mixtures.
OTC advertising in USA is regulated by Federal Trade Comission and not FDA as for prescribed medicines. The FDA requires that OTC products are labeled with an approved “Drug Facts” label to educate consumers about their medications. These labels comply to a standard format and are intended to be easy for typical consumers to understand. Drug Facts labels include information on the product’s active ingredient(s), indications and purpose, safety warnings, directions for use, and inactive ingredients.
