Is Gastromark Safe in Breastfeeding

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

Gastromark is not approved for marketing in the United States by the U.S. Food and Drug Administration. No information is available on the clinical use of Gastromark during breastfeeding. If Gastromark is required by the mother, it is not a reason to discontinue breastfeeding.[1] However, because there is no published experience with Gastromark during breastfeeding, other agents may be preferred, especially while nursing a newborn or preterm infant.
