Magnesium Hydroxide Levels and Effects while Breastfeeding

Summary of Use during Lactation

Magnesium hydroxide is acceptable to use during breastfeeding.

Drug Levels

Maternal Levels. Ten pre-eclamptic mothers were given 4 grams of magnesium sulfate intravenously followed by 1 gram per hour until 24 hours after delivery. Average colostrum magnesium levels at the time of discontinuation of the infusion were 64 mg/L in treated women and 48 mg/L in the controls. By 48 hours after discontinuation, colostrum magnesium levels were only slightly above control values and by 72 hours they were virtually identical to controls.[1] The maternal serum magnesium levels with intravenous magnesium sulfate are much higher than would be expected with magnesium hydroxide orally.

Infant Levels. Relevant published information was not found as of the revision date.

Effects in Breastfed Infants

Fifty mothers who were in the first day postpartum received 15 mL of either mineral oil or an emulsion of mineral oil and magnesium hydroxide equivalent to 900 mg of magnesium hydroxide, 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]
