Bismuth Subsalicylate Levels and Effects while Breastfeeding
Summary of Use during Lactation
Because of the possibility of absorption of salicylate from the breastmilk by the infant, alternatives are preferred.
Maternal Levels. No published information was found on the use of bismuth subsalicylate during breastfeeding. Infant salicylate intake is estimated to be less than 1% of the maternal dose when both drug and metabolite are considered.
Infant Levels. Relevant published information was not found as of the revision date.
Effects in Breastfed Infants
One case report of metabolic acidosis was caused by salicylate in a 16-day old breastfed infant whose mother was taking aspirin 650 mg every 4 hours for arthritis. However, there was no measurement of salicylate in maternal serum or milk and it is unclear whether the infant had received any salicylate directly.
