Is Verapamil Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Verapamil? Is Verapamil safe for nursing mother and child? Does Verapamil extracts into breast milk? Does Verapamil has any long term or short term side effects on infants? Can Verapamil influence milk supply or can Verapamil decrease milk supply in lactating mothers?

It is excreted in breast milk in clinically non-significant amount and no problems have been observed in infants whose mothers were receiving this treatment.Plasma levels in these infants were undetectable or very low. Verapamil may induce to an increase of plasma Prolactin levels. American Academy of Pediatrics: usually compatible with breastfeeding medication.WHO List of Essential Medicines 2002: compatible with breastfeeding.

Limited information indicates that maternal doses of verapamil up to 360 mg daily produce low levels in milk and newborns may have detectable verapamil serum levels, but levels are low. Verapamil would not be expected to cause any adverse effects in breastfed infants, especially if the infant is older than 2 months.

No adverse reactions have been reported among 3 infants aged 13 days, 8 weeks and 3 months who were exposed to verapamil in breastmilk.[2][3][4]

Verapamil can cause hyperprolactinemia and galactorrhea.[5][6] The clinical relevance of these findings in nursing mothers is not known. The maternal prolactin level in a mother with established lactation may not affect her ability to breastfeed.
