Can levothyroxine 50 mg shrink multiple nodules? It brought TSH down to 0.7 uUI/ml, T3 (liothyronine) to 3.57 pmol/L, but T4=20, 3 pmol/L which is normal high range.

Thyroid nodules. Yes, thyroid medication may shrink nodules. The dose you mentioned is probably 50 micrograms (mcg). If any of the nodules increase in size it will require a fine needle aspiration. Monitor closely. .
Doesn't work. Hi. It's been long known that trying to shrink thyroid nodules with levothyroxine (LT4) doesn't work. Depending on the size of the nodules, they may need to be assessed to make sure they are not thyroid cancer. I'd suggest you see an experienced endocrinologist who knows how to evaluate thyroid nodules. Good luck!
