S.T.
I haven't had a thyroid issue but my mom, sister and brother all do and take the generic thyroid replacement medication every day. It's very cheap and effective - none of them have ever had any issues. They get a blood test each year to see if there's any change in their hormone levels and their medication might be adjusted. My mom is 81 and has been taking this medication for more than 60 years - her dosage has been adjusted maybe 3 times ever in her life. My sister who is 57 and brother who's 46 have very similar stories. If you have to have a medical disorder that's the least serious and most easily treated. Good luck!
