Before 4 months I was detected as hypothyroid, my TSH was 32.00. My doctor prescribed for 1+1/2 dose of Eltroxin every day. I am continuing the medicine and now TSH is 0.005, T3 is within the range and T4 is slightly higher than the upper level. Please suggese me whether I need to continue the same dose or not? Why TSH has lowered so much? Please reply.......
