Other truthful and nonmisleading statements, describing only the indications for use that have been established and listed in this paragraph (b), may also be used, as provided in 330.1(c)(2) of this chapter, subject to the provisions of section 502 of the act relating to misbranding and the prohibition in section 301(d) of the act against the introduction or delivery for introduction into interstate commerce of unapproved new drugs in violation of section 505(a) of the act.

(1) "Do not take more than (maximum recommended daily dosage, broken down by age groups if appropriate, expressed in units such as tablets or teaspoonfuls) in a 24-hour period, or use the maximum dosage of this product for more than 2 weeks, except under the advice and supervision of a physician."

(e) Directions for use. The labeling of the product contains the recommended dosage, under the heading "Directions", per time interval (e.g., every 4 hours) or time period (e.g., 4 times a day) broken down by age groups if appropriate, followed by "or as directed by a physician."

(f) Exemption from the general accidental overdose warning. The labeling for antacid drug products containing the active ingredients identified in 331.11(a), (b), and (d) through (m); permitted combinations of these ingredients provided for in 331.10; and any of these ingredients or combinations of these ingredients in combination with simethicone (identified in 332.10 of this chapter and provided for in 331.15(c)), are exempt from the requirement in 330.1(g) of this chapter that the labeling bear the general warning statement "In case of accidental overdose, seek professional assistance or contact a poison control center immediately."
