What the monograph permits

What the label may say
The monograph fixes both what the product must call itself and the indication wording it may use. These are the permitted phrases, verbatim; a product may not claim more than this.
Statement of identity
(a) Statement of identity. The labeling of the product contains the established name of the drug, if any, and identifies the product as a "cough suppressant" or an "antitussive (cough suppressant)."21 CFR 341.74(a)
Permitted indication
(2) "Temporarily" (select one of the following: "alleviates," "calms," "controls," "decreases," "quiets," "reduces," "relieves," or "suppresses") "cough" (select one of the following: "as may occur with," "associated with," or "occurring with") (select one of the following: "A cold," "the common cold," or "inhaled irritants").21 CFR 341.74(b)(2)
The warning the label must carry
(1) For oral and topical antitussives. "A persistent cough may be a sign of a serious condition. If cough persists for more than 1 week, tends to recur, or is accompanied by fever, rash, or persistent headache, consult a doctor."21 CFR 341.74(c)(1)
Camphor is a topical antitussive, but unlike menthol the monograph gives it NO lozenge form: it is permitted only as an ointment or for steam inhalation. That is why there is no camphor cough drop. It is included here to make that absence explicit.
On the shelf
The monograph permits camphor, but no lozenge, pastille, troche or gum in the current FDA listing contains it . A permitted ingredient is not the same as an ingredient on a shelf, and this is one that is on the books without being in the box. Not currently listed
This page reports what the FDA monograph permits, not what you should take. It is not medical advice, and it makes no claim that camphor is effective for any condition. Always follow the product label, and ask a pharmacist or a doctor.
