CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN 
                          SERVICES (CONTINUED)
 
PART 201 LABELING--Table of Contents
 
       Subpart C Labeling Requirements for Over-the-Counter Drugs
 
Sec.  201.70  Calcium labeling.

    (a) The labeling of over-the-counter (OTC) drug products intended 
for oral ingestion shall contain the calcium content per dosage unit 
(e.g., tablet, teaspoonful) if the calcium content of a single maximum 
recommended dose of the product (which may be one or more dosage units) 
is 20 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 calcium content shall be expressed in milligrams or grams 
per dosage unit and shall include the total amount of calcium regardless 
of the source, i.e., from both active and inactive ingredients. If the 
dosage unit contains less than 1 gram of calcium, milligrams should be 
used. The calcium content per dosage unit shall be rounded-off to the 
nearest 5 milligrams (or nearest tenth of a gram if over 1 gram). The 
calcium 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 calcium present in the labeled maximum daily dose of the 
product is more than 3.2 grams: ``Ask a doctor before use if you have 
[in bold type] [bullet]\1\ kidney stones [bullet] a calcium-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 calcium or sodium restricted diet.
