Carcinogenesis, Mutagenesis and Impairment of Fertility
Long-term studies in animals have not been performed to evaluate carcinogenic potential.
Pregnancy Category C
Animal reproduction studies have not been conducted with benzoyl peroxide. It is also not known whether benzoyl peroxide can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Benzoyl peroxide should be given to a pregnant woman only if clearly needed.
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when benzoyl peroxide is administered to a nursing woman.
Safety and effectiveness in pediatric patients under the age of 12 have not been established.
Benzoyl peroxide is an antibacterial agent which has been shown to be effective against Propionibacterium acnes. This action is believed to be responsible for its usefulness in acne. One study in the rhesus monkey demonstrated a percutaneous absorption of about 1.8 µg per cm2 of benzoyl peroxide or 45% of the applied dose in a 24-hour period. The absorbed benzoyl peroxide was completely converted in the skin to benzoic acid.
