Yes, 41 is high, and yes, of course you should have a follow up appointment scheduled. 4-6 weeks to see if that dosage
is correct for you. It may be too high
and you could go hyper, again. But it's likely your TSH of 41 will come down to within reference range with this dosage.
But TRUST ME... unless you have extensive dealings with this doc, he is just guessing at your dose of Levoxyl. It's the S.W.A.G. (Sophicated Wild-A$$ Guess) method of medicine every endocrinologist practices.
