Reading a medicine label is easier when you can separate three ideas: what the active ingredient does, how the finished product should be used, and the regulatory conditions for selling it. The sections below explain those connections.
Reading an OTC Drug Facts label
Start with the medicine's intended use, then check its warnings and directions. Being available without a prescription does not make a medicine appropriate for every person or every symptom. Similar product names can also hide different ingredients.
The FDA guide to Drug Facts labels explains the standard sections, including the active ingredient, purpose, uses, warnings, directions and inactive ingredients.
Active and inactive ingredients
An active ingredient produces the medicine's intended therapeutic effect. Happy Cappy Medicated Shampoo & Body Wash lists pyrithione zinc 0.95% as its active ingredient. The pyrithione zinc guide explains its role.
Inactive ingredients make up the rest of the formula. They can have useful jobs such as cleansing, supporting texture or preserving the product. The word inactive distinguishes them from the labeled drug active. It does not mean they have no function.
OTC monographs set conditions for medicines
An OTC monograph establishes conditions for a category of nonprescription medicines. These can include the active ingredients, uses, amounts, method of administration, labeling and testing. The conditions apply together.
Medicines meeting the applicable monograph and other legal requirements can be marketed without an individually approved drug application. That pathway differs from FDA approval of a particular product through a drug application. Read the FDA explanation of the two pathways.
GRASE means generally recognized as safe and effective
GRASE is short for generally recognized as safe and effective. In the OTC monograph framework, it refers to use under the specified conditions. It is not a claim that an ingredient is suitable at any concentration, for any condition or for every person.
The FDA overview of OTC monographs explains how the framework defines these conditions. Monograph status does not replace the directions and warnings on the product's label.
