Hi. During initial pregnancy tests in Dec 10 , my TSH was found to be 5.92. So my gynae advised Thyrox-25 once daily. I have been taking it for past 18 months regularly. During this time, however, TSH level changed to 2.76 in Jan 11, 2.02 in May 11, 2.23 in May 11. After 2 months post-delivery, T3 was 4.6, T4 1.9 and TSH 1.75 on Sep 11; Now as on Apr 12, T3 is 2.6, T4 is 0.89 and TSH is 6.91 in one lab and 2.54, 0.94, 4.48 in another lab. Please let me know if I should continue with Thyrox-25 or stop it or increase the dosage?
