Is Istomar Safe in Breastfeeding

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

Drug which is commonly used in pediatric therapy even for newborn treatment. Excreted in high amount into breast milk although infant intake is reportedly lower than usual therapeutic dose. No side effects on breastfed babies have been reported. Increase of Prolactin levels has been shown, yet it does not induce galactorrhea.

Although interpatient variability exists, the dose of Istomar in breastmilk is less than the dose used in newborn infants. Maternal Istomar would not be expected to cause any adverse effects in breastfed infants. No special precautions are required.

One 54-day-old breastfed infant had no observable adverse effects after maternal ingestion of Istomar 150 mg every 12 hours for 2 days.[2]

Histamine H2-receptor blockade is known to stimulate prolactin secretion.[3] Istomar in intravenous doses over 100 mg or during long-term oral use have increased serum prolactin in some studies, and rare cases of gynecomastia have been reported.[4][5][6][7][8] The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
