Sec.  201.72  Potassium labeling.

    (a) The labeling of over-the-counter (OTC) drug products intended 
for oral ingestion shall contain the potassium content per dosage unit 
(e.g., tablet, teaspoonful) if the potassium content of a single maximum 
recommended dose of the product (which may be one or more dosage units) 
is 5 milligrams or more. OTC drug products intended for oral ingestion 
include gum and lozenge dosage forms, but do not include dentifrices, 
mouthwashes, or mouth rinses.
    (b) The potassium content shall be expressed in milligrams or grams 
per dosage unit and shall include the total amount of potassium 
regardless of the source, i.e., from both active and inactive 
ingredients. If the dosage unit contains less than 1 gram of potassium, 
milligrams should be used. The potassium content shall be rounded-off to 
the nearest 5 milligrams (or nearest tenth of a gram if over 1 gram). 
The potassium content per dosage unit shall follow the heading ``Other 
information'' as stated in Sec.  201.66(c)(7).
    (c) The labeling of OTC drug products intended for oral ingestion 
shall contain the following statement under the heading ``Warning'' (or 
``Warnings'' if it appears with additional warning statements) if the 
amount of potassium present in the labeled maximum daily dose of the 
product is more than 975 milligrams: ``Ask a doctor before use if you 
have [in bold type] [bullet]\1\ kidney disease [bullet] a potassium-
restricted diet''. The warnings in Sec. Sec.  201.64(c), 201.70(c), 
201.71(c), and 201.72(c) may be combined, if applicable, provided the 
ingredients are listed in alphabetical order, e.g., a magnesium or 
potassium-restricted diet.
