Answer by Dr. Ru: About Aspirin usage in lactation

Excreted in non-significant amount into breast milk. Reye’s Syndrome has never been reported due to ASA through breast milk. It is thought to be highly unlikely to occur after isolated or small doses like those used for treatment of thrombosis or anti-abortion therapy. At high maternal dose, one case (dubious) of salicylic intoxication in the neonatal period and another case of thrombocytopenia in an infant have been reported. Likelihood of hemolysis should be considered in those patients with G6PD-deficiency. WHO Model List of Essential Medication: compatible while breastfeeding when used occasionally or small dose for antithrombotic prophylaxis management.

Answer by DrLact: About Aspirin usage in lactation

After aspirin ingestion, salicylic acid is excreted into breastmilk, with higher doses resulting in disproportionately higher milk levels. Long-term, high-dose maternal aspirin ingestion probably caused metabolic acidosis in one breastfed infant. Reye's syndrome is associated with aspirin administration to infants with viral infections, but the risk of Reye's syndrome from salicylate in breastmilk is unknown. An alternate drug is preferred over continuous high-dose, aspirin therapy. After daily low-dose aspiring (75 to 325 mg daily), no aspirin is excreted into breastmilk and salicylate levels are low. Daily low-dose aspirin therapy may be considered as an antiplatelet drug for use in breastfeeding women.[1][2][3].

Aspirin Side Effects in Breastfeeding

A 16-day-old breastfed infant developed metabolic acidosis with a salicylate serum level of 240 mg/L and salicylate metabolites in the urine. The mother was taking 3.9 g/day of aspirin for arthritis, and salicylate in breastmilk probably caused the infant's illness, but the possibility of direct administration to the infant could not be ruled out.[11] Thrombocytopenia, fever, anorexia and petechiae occurred in a 5-month-old breastfed infant 5 days after her mother started taking aspirin for fever. One week after recovery, the infant was given a single dose of aspirin 125 mg and the platelet count dropped once again. The original symptoms were probably caused by aspirin or salicylate in breastmilk.[12] Hemolysis after aspirin and phenacetin taken by the mother of a 23-day-old, glucose-6-phosphate dehydrogenase (G6PD) deficient infant was possibly due to aspirin in breastmilk.[13] In a telephone follow-up study, mothers reported no side effects among 15 infants exposed to aspirin (dosages and infant ages were unspecified) in breastmilk.[14]
