I was diagnosed with Graves disease in 2002. They started me out on Tapazole. Changed doctors and he put me on PTU because he said pregnant women can even take PTU. I was definitely not pregnant. He was trying to say that it is milder than tapazole.
Took the tapazole for about two months. I had no problems with it. Usually with the tapazole, you don't have to take so many pills as with PTU.
I noticed with the PTU I had a little hand and feet swelling.
My MD never told me that after my thyroid levels normalize that I had to reduce the dose. I think I had hypothyroidism for quite a long time. My sideeffects I thought were symptoms of menopause.
When I found these boards, I learned much about the medicine. I believe you could talk to K9mom because she took tapazole I believe. All you have to do is ask for K9mom and you need some info on tapazole. She will definitely answer you.
Good luck and take care
