ve been on
generic, Synthroid
and Levoxyl at one time or another,
and I found absolutely no
difference among them. However, my endo is one who doesn't like generic. He put me on Levoxyl. You have to chose your battles, I guess, so I'm keeping him happy.
Interestingly enough, after switching to Levoxyl from generic (same dose), my labs actually took a nose dive.
