Is Magmesia hydrate Safe in Breastfeeding

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

Ingested Magnesium does not concentrate into breast milk.. Naturally occurring, the mean Magnesium concentration in the milk is 31 mg/L (range 15 – 64 mg/L) and not affected by the ingestion of Magnesium. Because of a low oral bioavailability the pass from the breast milk toward the infant's plasma is hampered, except in premature and newborn infants who may exhibit a higher intestinal absorption due to an increased permeability. Avoid chronic or excessive use. WHO Model List of Essential Medicines 2002: Magmesia hydrate is compatible with breastfeeding.

A study on the use of Magmesia hydrate during breastfeeding found no adverse reactions in breastfed infants. Intravenous magnesium increases milk magnesium concentrations only slightly. Oral absorption of magnesium by the infant is poor, so maternal Magmesia hydrate is not expected to affect the breastfed infant's serum magnesium. Magmesia hydrate supplementation during pregnancy might delay the onset of lactation, but it can be taken during breastfeeding and no special precautions are required.

Fifty mothers who were in the first day postpartum received 15 mL of either mineral oil or an emulsion of mineral oil and Magmesia hydrate equivalent to 900 mg of Magmesia hydrate, although the exact number who received each product was not stated. Additional doses were given on subsequent days if needed. None of the breastfed infants were noted to have any markedly abnormal stools, but all of the infants also received supplemental feedings.[2]

One mother who received intravenous magnesium sulfate for 3 days for pregnancy-induced hypertension had lactogenesis II delayed until day 10 postpartum. No other specific cause was found for the delay, although a complete work-up was not done.[3] A subsequent controlled clinical trial found no evidence of delayed lactation in mothers who received intravenous magnesium sulfate therapy.[4] Some, but not all, studies have found a trend toward increased time to the first feeding or decreased sucking in infants of mothers treated with intravenous magnesium sulfate during labor because of placental transfer of magnesium to the fetus.[4][5] A study in 40 pairs of matched healthy women with vaginally delivered singleton pregnancies, outcome endpoints were compared in those receiving continuous oral magnesium aspartate HCl supplementation mean dose of 459 mg daily (range 365 to 729 mg of magnesium daily) for at least 4 weeks before delivery versus non-supplemented controls. In the magnesium group, significantly fewer women could breastfeed their infants exclusively at discharge (63% vs 80%).[6]
