Before my thyroid was removed, I was on 100 mcg or 0.1 mg. Now I'm on 0.15mg (150mcg) and I no longer have a thyroid gland (I had it surgically http://www.medications.com/effect/view/33781?item=11552 Wed, 17 Sep 2008 21:36:34 -0400 http://www.medications.com/effect/view/33781?item=12466 Have you had the two antibodies tests?
