I am a 52 year old female who was diagnosed as hypothyroid 20 years ago. I have been treated with a daily dose of 150 mcg Levoxyl for almost that long. A new family doctor mistakently prescribed 100 mcg in March. I took this dose for a month before I realized the error. Bloodwork, at that time, showed a TSH of 26.5 and a Free T4 of .86. My dose was adjusted to 175 mcg, which I took for 3 months, when labs in July showed my TSH at .03 and Total T4 of 14.3. Since July, I have been back on the originial dose of 150 mcg and bloodwork just taken shows my TSH at .03 with a total T4 of 11.6 Previous labwork from 2004, 2006 and 2007 had my TSH with levels from .29 to 2.76 with a Free T4 of 1.11. My question is - am I hyper or hypo-thyroid? And, do you think staying on my current daily dose of 100 mcg is the proper treatment? I also take 60 mg of Prozac daily and 1 tablet of Lipitor as well as a multi-vitamin and calcium and D3 supplement.
