I was switched by my pharmacy from Synthroid to the generic, Levoxyl, about 6 months ago and seemed to have developed a facial rash which is somewhat splotchy over my cheeks (more on one side than the other). Is it possible for generics to cause this kind of a reaction. My TSH levels seem to remain in check ranging from 1.0 - 2.25. I am currently on 200mcg/day.
