In addition to the problem with
Armour mentioned by LM, the 60 mg
Armour is not enough to
substitute for 137 of Synthroid. According to readily available conversion charts, 80 mg would be the right amount. Personally, I would not even consider changing back to Synthroid at this time, and risking further hypo problems during the switch. I would take the additional Armour, or better yet, make a switch to Nature-throid, which is basically the equivalent of Armour, without its recent problems.
