I have had labs on both Armour Thyroid (5 grains daily) and Erfa Thyroid (5 grains daily). I had been on both drugs for three months before going to the lab (in June and September 2015 respectively). These are the results:
Armour (5 grains):
TSH <0.01 (ref 0.2-4.0)
FT4 1.1 (0.8-1.8)
FT3 2.9 (2.2-4.2)
Erfa (5 grains):
TSH <0.01 (same ref ranges)
I always go to the lab 24 hours after taking NDT.
My FT3 levels were at the upper normal range 24 h after taking Erfa, but barely midrange 24 h after taking Armour. Should I interpret this to mean that Armour does not work optimally for me, or that I am overmedicated on Erfa? I guess those results mean that my FT3 levels are twice the upper normal range right after taking Erfa...
Would it be a good idea to have labs right after taking Armour Thyroid, instead of waiting 24 hours? Or should I raise the dose? Or just forget about Armour, and go for Erfa instead?
