Had my tsh checked this past july came back normal 2.580. dr said to stay on .137 mc of levothyroxine. do you agree with dosage?

Sounds reasonable: With a TSH in the normal range, there's no reason to change your dose.

Yes.: TSH is an indirect measure of thyroid function. The range is between .4 to 4.0 depending on the lab. 2.3 is good . It also usually collaborated with clinical symptoms.

Yes: yes as long as the TSH stays normal and you are feeling well.

Hypothyroidism: Hi, if your TH and Ft4 are within normal values and you have no symptoms of hyper/hypothyroidism then your doctor recommendation seems reasonable. Take care.

Depends: I have no idea how long you've been treated, what your diagnosis and the reason for L-thyroxine, or if you've had doseage adjustments for symptoms on the past. The TSH level suggests this is appropriate, but you should have other thyroid function numbers handy to answer that question completely. Check with your Endo about that to get your answer

Normal range: When treating under active thyroid ( hypothyroidism) we usually try to keep TSH in normal range, so if the TSH is normal, dosage would remain the same.
