Mr. lybrate-user, Thanks for the query. Usually antithyroid drug treatment is given for 18 to 24 months. During that period when TSH levels return to around 3 - 4 mU/L (normal range 0.4 to 5 mU/L), thereapy is discontinued. If there is relapse after a few weeks or months same drug may be repeated for another course. However, it is noticed that longer usage hardly produces any benefit. That thyroid function does not return to normal (or remains high). Therefore, I am a bit surprised that you have been on ATD for over 10 years. Another aspect your TSH level is also pretty low (0.01 mU/L), suggestive of not much benefit from the on going therapy. Please clarify if you have consulted any endocrinologist during recent time? If yes what was the opinion of that doctor? Usually to achieve better results other options like Radio Active Iodine (RAI) or surgery are considered when relapses continue to occur. Therefore, please come back with answers to my queries. Thanks.
