Very Low Risk
Even though it is metabolized to mercaptopurine, just tiny amounts of this drug have been found in breast milk (4 - 18 micrograms/liter).
Among several breastfed infants of mothers who were treated with Azathioprine failed to be detected in the blood nor side effects were found. Long-term infectious diseases were not more common among exposed infants.
Exposition would be minimized if nursing is resumed 3 hours after last dose.
We do not have alternatives for Azathioprine since it is relatively safe.
Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
Thank you for helping to protect and promote breastfeeding.
