Patricia, I just had a patient who started Nifedipine for postpartum high blood pressure. She is also taking one dose per day. She is pumping breastmilk for her preemie (32 weeks) in the NICU and the neonatologists have OK'd it for the baby. As with lots of meds, I simply advised her to take the med after pumping and wait about 3 hours before pumping to decrease the amount of drug in the breastmilk. According to Hale, Nifedipine is approved by the AAP for use in breastfeeding mothers. The studies quoted conclude that the amount ingested via breastmilk poses little risk to an infant.
