Sec. 201.64 Sodium labeling.

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 sodium content shall be expressed in milligrams per dosage
unit and shall include the total amount of sodium regardless of the
source, i.e., from both active and inactive ingredients. The sodium
content shall be rounded-off to the nearest whole number. The sodium
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 sodium present in the labeled maximum daily dose of the
product is more than 140 milligrams: ``Ask a doctor before use if you
have [in bold type] [bullet]\1\ a sodium-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

bicarbonate, sodium phosphate, or sodium biphosphate as an active
