Benzoyl peroxide warning to avoid "unnecessary sun exposure" proposed by FDA.

BENZOYL PEROXIDE LABEL WARNING TO AVOID "UNNECESSARY SUN EXPOSURE" is recommended by FDA in a Feb. 17 notice of proposed rulemaking establishing additional labeling for all topically applied acne treatment drug products containing benzoyl peroxide. FDA has tentatively determined that because "some harm may result from exposure to sunlight in conjunction with the use" of benzoyl peroxide products, "consumers who use products containing this ingredient need to be informed about an additional condition related to this use, i.e., to avoid unnecessary sun exposure and to use a sunscreen," the Federal Register notice states.
