My dr has prescribed me liothyronine t3 thyroid replacement for hypothyroidism. I am breastfeeding a 1 y.o. conflicting studies say its fine to take with others saying it's unsafe. Even my pharmacist said no studies on nursing infants have been done and to use at my discretion. I am curious to hear from anyone else who is breastfeeding on cytomel or any other liothyronine meds. Worried.
