I have to take Propylthiouracil, 300mg/day. Can I continue to breastfeed my 13 months-old baby?
Is it safe?
Your doctor should be able to guide you more but this is the recommendation:
Propylthiouracil Breastfeeding Warnings
In one study, nine lactating women were administered 400 mg of propylthiouracil by mouth. The mean amount of propylthiouracil excreted during 4 hours after drug administration was 0.025% of the administered dose.
Propylthiouracil is excreted into human milk in small amounts and therefore likely results in clinically insignificant doses to the suckling infant. While adverse effects in the nursing infant are not reported, the manufacturer considers propylthiouracil to be contraindicated during lactation. However, propylthiouracil is considered compatible with breast-feeding by the American Academy of Pediatrics.
