When my labs were still low, during my 2nd administering of Thyroid meds, I was perscribed 3/4 a grain of Armour. (many say THAT is small)
So I'd have to agree that 1/8 grain is a very tiny dose, that shouldn't have many side-effects while tappering off of the medicine. Do what your doctor suggests though.
Since there is such a contraversy as to what " NORMAL "
bloodwork is, do you happen to have copies of the labwork ?
Irritated is no way to live. Hope you feel better
