Answer by Dr. Ru: About Sildenafil usage in lactation

A 5-phosphodiesterase inhibitor used in the treatment of pulmonary hypertension, erectile dysfunction in men, Raynaud's syndrome and in other treatments due to its vasodilatory effect on smooth muscle. Its use is authorized in small infants and neonates to treat pulmonary hypertension (Lakshminrusimha 2016, Krishnan 2010). Sildenafil and its metabolite N-desmethylsildenafil are excreted in breast milk in clinically insignificant amounts, much lower than the dose used in newborns and infants (Wollein 2016).

Limited data indicate that sildenafil and its active metabolite in breastmilk are poorly excreted into breastmilk. Amounts ingested by the infant are small and would not be expected to cause any adverse effects in breastfed infants.
