Pregnancy and lactation
Pregnancy
Usage In Pregnancy - Pregnancy Category C No teratogenic effects were observed in rats when papaverine hydrochloride was administered subcutaneously as a single agent. It is not known whether papaverine can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Papaverine Hydrochloride should be given to a pregnant woman only if clearly needed.
Lactation
Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when papaverine hydrochloride is administered to a nursing woman.
Breastfeeding (LactMed)
No information is available on the use of papaverine during breastfeeding. If a mother requires papaverine, it is not a reason to discontinue breastfeeding. Until more data become available, papaverine should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. If papaverine is used, monitor the infant for sedation and poor feeding, especially in younger, exclusively breastfed infants.
