Is Nifedipine Safe in Breastfeeding

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

Excreted into breast milk in non-significant amount with no problems among breastfed infants whose mothers were treated with this medication. No alteration on breast milk composition has been seen. Shown to be effective at a dose of 10 - 20 mg three times-a-day for pain relief related to Raynaud's phenomena of the nipple, which is a highly painful vasospasm triggered by cold exposition or trauma produced by inadequate latch-on to the breast. Side effect on the mother should be addressed. American Academy of Pediatrics 2001: Maternal Medication Usually Compatible With Breastfeeding. Eleventh WHO Model List of Essential Drugs 2002: Compatible with breastfeeding.

Because of the low levels of nifedipine in breastmilk, amounts ingested by the infant are small and no adverse effects have been reported among a limited number of infants exposed to nifedipine in breastmilk. Nifedipine is used to treat painful nipple vasospasm (e.g., Raynaud phenomenon) in nursing mothers.[1]

No adverse reactions have been reported among infants exposed to nifedipine in breastmilk mostly at maternal dosages of 30 mg daily beginning shortly postpartum and continuing for up to 6 months in some.[2][5][6][7][8][9][10][11]

No direct effects are known. However, nifedipine has been used to decrease the pain of nipple vasospasm (or Raynaud phenomenon of the nipple), allowing mothers to continue nursing who might otherwise discontinue breastfeeding. The dosage of nifedipine reportedly used to treat the condition is 30 to 60 mg daily either as a single dose of a sustained-release product or 10 to 20 mg 3 times daily of an immediate-release product. Lower dosages can be tried if these doses are not tolerated.[1][6][7][8][9][12] Nifedipine had no effect on milk composition (sodium, potassium, calcium, chloride, nitrogen, phosphorus and total lipids) in one woman.[3]
