Do wrong words matter on supplement, cosmetic and pharmacy labels too?

Yes. The same federal law that covers drug labels also says a food is misbranded if its labeling is false or misleading in any particular (21 U.S.C. 343), and the same goes for a cosmetic (21 U.S.C. 362). A dietary supplement is deemed to be a food under the Act (21 U.S.C. 321(ff)). A correctly spelled wrong word that changes what a line means is a problem on any of these labels.

This page is general information, not legal or regulatory advice.

Dietary supplements

Supplement labels carry their own nutrition panel under 21 CFR 101.36, and supplements fall under the food misbranding section of the law. Required label text must be in English, and if the label uses another language, the required text must appear in that language too (21 CFR 101.15).

Cosmetics

Cosmetic labeling is misbranded if it's false or misleading in any particular (21 U.S.C. 362). Cosmetic labels follow the same English and second-language rule (21 CFR 701.2).

Pharmacy dispensing labels

A drug dispensed on a prescription is exempt from most of the standard drug labeling requirements if its label carries the dispenser's name and address, the prescription's serial number and date, the prescriber's name, the patient's name if stated in the prescription, and the directions for use and cautionary statements, if any, contained in the prescription (21 U.S.C. 353(b)(2)). Our view: these are often the words a patient reads most closely, so a wrong word there goes straight to the patient.

What carries over from drug labels

Our view: the habit is the same everywhere. Read the lines that tell someone what to do or what to avoid for meaning, not just for spelling. See how to proofread label sections for meaning and the drug-label rules in what rules govern the exact wording on a drug label.
