[DAW2]

Members don't see this ad.

ok so if synthroid and levoxyl are not interchangeable, how is it that both go to the same generic?
im confused as a mug

Because the manufacturer of the generic got it AB rated to both products and, I would assume, the makes of the two branded products didn't AB rate them to each other.


In reality, it's fine to interchange them as you please....legally, hell if I know....
