Nitroglycerin Levels and Effects while Breastfeeding
Summary of Use during Lactation
Topical use of nitroglycerin for anal fissures by nursing mothers appears to have no adverse effects on their breastfed infants. Topical use on the nipples has been used for alleviation of Raynaud phenomenon of the nipples, but only after cessation of breastfeeding. It should not be used topically on the nipples during breastfeeding. Sublingual and intravenous nitroglycerin have not been studied during breastfeeding. Observe infants for flushing and discomfort after breastfeeding.
