Tsh up from 0.01- rapid hrate. Now tsh 3.29 why raise Synthroid (thyroxine) to 112 mcg if tsh level normal on 1/2 112 mcg. Confused? Also, taking Ativan 0.05.

More info needed. Without more information about history and medication adjustments, we can't speculate on the dosing of the Synthroid (thyroxine). TSH of 3.29 is in the normal range for most labs, and by itself would not usually indicate a need for dosage adjustment.
