Hi, Penny
I took PTU for 15 years, and was not aware of any longterm bad effects. In the rest of the world, this is not unusual; only in the U.S. is there such a push to RAI, and in large doses, too.
Of course, I am just one example; others may have had bad long-term effects. Do keep in mind that all treatment options have their downsides.
I encourage you to consider long-term anti-thyroid meds.
