I addressed your issue in your other post........ but would like to add
It's correct that generics and brand names may not be created equal......... some actually do better on generic than on brands....... I was one who did.
You can fluctuate between hypo and hyper. A good website to look into is www.*********************.com
You probably need more than what Synthroid provides. P.S. - You mentioned you were on Levoxyl--if you change meds to/from Synthroid, do so only under supervision of your doctor. It's not like a lot of generics/brand names where you can switch back and forth. They are NOT equal.
