Fertility: There are no data on the effects of mupirocin on human fertility. Studies in rats showed no effects on fertility (see Pharmacology: Toxicology: Pre-Clinical Information under Actions).
Pregnancy: Adequate human data on use during pregnancy are not available. Studies in animals do not indicate reproductive toxicity (see Pharmacology: Toxicology: Pre-Clinical Information under Actions).
Mupirocin should only be used in pregnancy when the potential benefits outweigh the potential risks associated with treatment.
Lactation: Adequate human and animal data on use during lactation are not available.
If a cracked nipple is to be treated, it should be thoroughly washed prior to breast-feeding.
