Treprostinil Levels and Effects while Breastfeeding
Summary of Use during Lactation
One patient taking treprostinil breastfed her infant for one year without any complications. If treprostinil is required by the mother, it is not a reason to discontinue breastfeeding. However, until more data are available, treprostinil should only be used with careful monitoring during breastfeeding.

Effects in Breastfed Infants
A woman developed pulmonary artery hypertension and was treated with intravenous treprostinil beginning at 32 weeks of gestation and titrated up to 26 ng/kg/min. The dose was nearly doubled postpartum because of worsening symptoms. She breastfed (extent not stated) her infant for one year with no apparent drug-related problems, although there was concern for obesity at 6 months of age. The infant was healthy and developing normally at 2 years of age.
