I yesterday got my test results and my TSH level is 15. T3 & T4 seems to be normal 1.3 and 7.06 . Last time I had this high TSH level, doctor recommended 100 MCG thyronorm tablets. After a month, the TSH dropped to 0. So, I continued with 12.5 MCG tablets. After a week, the level increased a little bit to 0.5 but after a month, my TSH is again 15 I'd like to know what dosage is recommended when TSH is 15 and what dosage should I take if it drops to 0 because of high dosage intake? Thanks and regards Sakshi
