What "OTC monograph drug" means on a label

What a monograph is

A monograph is a standing rule book for a whole category of over-the-counter medicine. It sets out which active ingredients are permitted, at what strengths, in which dosage forms, and what the label has to say. A product that stays inside its monograph can be marketed without FDA reviewing it individually.

That is why a cough drop costs what it does. The alternative route, an approved drug application, is the one nicotine lozenges take, and it involves a submission to FDA for each product.

(iii) For products containing menthol identified in § 341.14(b)(2) in a lozenge. The product contains 5 to 10 milligrams menthol. Adults and children 2 to under 12 years of age: Allow lozenge to dissolve slowly in the mouth. May be repeated every hour as needed or as directed by a doctor. Children under 2 years of age: Consult a doctor.21 CFR 341.74(d)(2)(iii)

One sentence in a regulation is why every menthol cough drop marketed as a cough suppressant is between five and ten milligrams. Not a convention, not a habit of the industry: a number in the rule.

The marketing categories you will see

Every FDA listing carries a marketing category, and it is the single most informative field on a product page. Across the 1,260 products here:

FDA National Drug Code Directory, retrieved 4 September 2026.

OTC MONOGRAPH DRUG means the product is marketed under a monograph. ANDA and NDA mean an approved application: a generic and an original respectively. UNAPPROVED HOMEOPATHIC and UNAPPROVED DRUG OTHER mean neither.

Monograph is not approval

A monograph product has not been reviewed by FDA before going on sale. What has been reviewed is the category: the ingredient, the strength range and the label wording were settled through rulemaking, sometimes decades ago, and the manufacturer is asserting that its product sits inside them.

The practical consequence is that the monograph guarantees a formulation, not a manufacturer. Two products with the same active ingredient at the same strength are making the same regulatory claim, which is the subject of a separate guide.

Unapproved homeopathic

21 listings here carry this category, including the best known zinc lozenges. It means the product is marketed as a homeopathic drug and has not been evaluated by FDA for safety or effectiveness before sale.

This site reports the category and stops there. It is a fact in the listing. Whether zinc shortens a cold is a question about clinical trials rather than about a registration database, and a listing-derived reference is not the right instrument for answering it.

Where to look it up

Every product page here shows the marketing category and, where there is one, the monograph identifier, linked to FDA's own register. The identifiers, what they are titled and which of them applies to a lozenge are set out on the monograph page, including the one that catches people out: there is no 21 CFR 356.
