I have hypothyroidism. My recent reports show the following readings T3 1.17 ng/ml Bio. Ref. Range 0.6 - 1.81 T4 13.20 ug/dl Bio. Ref. Range. 3.2 - 12.6 TSH 0.39 ulU/mL Bio. Ref. Range. 0.35 - 5.5. My physician has recommended that I take 100 mcg of Thyroxine Sodium Tablets (Thyronorm). I have made Hypothyroidism for over 12 year now and I have never had such low TSH levels. And I feel 100 mcg tablets are on a higher range and needs to be reduced. If I could get a recommendation as to what would be the proper dosage according to my reports it would be of great help and I can talk to my physician about it.
