Is it synthroid aka levothyroxine? Or is it Armor? Armor has shown to be less effective, and if you're mom is on a Part D plan they won't cover it at all.
I honestly have no idea about any of this. She's currently at work so I can't ask till later.
But if it's an insurance issue, shouldn't that have been explained and given her the option to pay for it herself before just passing her along a new medication?
