HELLO, Normal level of free T4 or free thyroxine is 0.7 to 2 and normal level of total T4 is about 4.5 to 12.5 , so if you have mentioned about free T4 then it is really a matter of concern and it goes toward the diagnosis of hyperthyroidism, but the level of your TSH is required for further diagnosis of hyperthyroidism whether it is due to primary disorder graves disease or secondarily due to increased TSH secretion from pituitary due to pituitary adenoma which will further need brain scan to diagnose it. for treating it you can take tab. carbimazole(neomercazole) 30mg/day or propylthyouracil 450 mg/day. monitor T3 and T4 level after 6-8 weeks if still increased thyroxine level then repeat the same drug for same interval and repeat again T3 and T4.if still resistant then increase the level of neomercazole by 15mg/day maximum of 120mg/day of neomercazole or 1200mg/day of propylthyouracil can be taken. If T3, T4 comes down to normal then tapper the dose of these drugs slowly over months to minium dose to mantain the euthyroid state. Its better to be in contact with a doctor regularly for further management of thyroid dysfunction.
