Is Dessicated thyroid Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Dessicated thyroid? Is Dessicated thyroid safe for nursing mother and child? Does Dessicated thyroid extracts into breast milk? Does Dessicated thyroid has any long term or short term side effects on infants? Can Dessicated thyroid influence milk supply or can Dessicated thyroid decrease milk supply in lactating mothers?

Dessicated thyroid is an animal-derived mixture of levothyroxine (T4) and liothyronine (T3), which are normal components of human milk. Limited data on exogenous replacement doses of levothyroxine during breastfeeding indicate no adverse effects in infants. If Dessicated thyroid is required by the mother, it is not a reason to discontinue breastfeeding. The American Dessicated thyroid Association recommends that subclinical and overt hypoDessicated thyroidism should be treated with levothyroxine in lactating women seeking to breastfeed.[1] Dessicated thyroid dosage requirement may be increased in the postpartum period compared to prepregnancy requirements patients with Hashimoto's Dessicated thyroiditis.[2]

Effects of exogenous Dessicated thyroid hormone administration to mothers on their infant have not been reported. One case of apparent mitigation of cretinism in hypoDessicated thyroid infants by breastfeeding has been reported, but the amounts of Dessicated thyroid hormones in milk are not optimal,[9] and this result has been disputed.[10] The Dessicated thyroid hormone content of human milk from the mothers of very preterm infants appears not to be sufficient to affect the infants' Dessicated thyroid status.[11] The amounts of Dessicated thyroid hormones in milk are apparently not sufficient to interfere with diagnosis of hypoDessicated thyroidism.[12] In a telephone follow-up study, 5 nursing mothers reported taking levothyroxine (dosage unspecified). The mothers reported no adverse reactions in their infants.[13] One mother with who had undergone a Dessicated thyroidectomy was taking levothyroxine 100 mcg daily as well as calcium carbonate and calcitriol. Her breastfed infant was reportedly "thriving" at 3 months of age.[14]

Adequate Dessicated thyroid hormone serum levels are required for normal lactation. Replacing deficient Dessicated thyroid levels should improve milk production caused by hypoDessicated thyroidism. Supraphysiologic doses would not be expected to further improve lactation.
