For Hyperthyroidism "I have Grave's disease causing hyperthyroidism and was on it from May to Oct. I have the tooth sensitivity issue really bad. Why don't the doctors and dentists know? I gained ten lbs back. I could stay up all night. But I think it helped that I exercised an hour each day. I'm off for only four days and now I'm tired and achy. I'm also on Toprol. My TSH is over now and my T4 is too low, but my Endo took me off of the methimazole for now. I'm happy about this because I don't like drugs. My hair is falling out and the texture is actually getting straighter. I think I had some other side effects, but I can't remember. I felt so horrible for a year, so at least I know it's Grave's disease hyperthyroidism... and not GCA or vertigo. It's been hell, so do the drug even a little. But sore throats should be reported immediately along with fevers. In May, I was on ten, then 20, then 30, then ten due to liver damage, then ten, now off in Oct."

For Hyperthyroidism "I’m taking this medication because I developed Graves’ disease. It is making me feel pretty crappy. The biggest issues are the extreme weight gain and the terrible chapped lips. I cannot get my lips to feel better no matter what I use or how much water I drink. I have been on the medication for 6 months. TSH is still lower than 0.05, but T3 and T4 are in the normal range now. I was taking 10 mg/day. Now taking 15 mg/day."

For Hyperthyroidism "I dropped 25 pounds and figured it was time to go to the doctor. Blood tests were run right away, and I was diagnosed with an overactive thyroid. Scans and ultrasounds were performed, and they all pointed to the same thing. My hair was brittle and breaking off when I combed it. I started taking vitamins for that, and they seem to be working, it's much softer now and not breaking off like before. I started taking methimazole less than 2 weeks ago, 5mg per day. I had blood work done the same week, and my doctor raised it to 35mg per day. My TSH level was 0.005. I was diagnosed with Graves' disease too. I guess it's too early to know if the medication is working, but at least I don't have any side effects like what I have been reading about on here from others. I have been taking my meds at night before bed, I read that it is absorbed better at night. I just take 4 pills all at once. I have 10mg and a 5mg. I wish they could make one pill of 35mg. I hope to put some weight back on soon."

For Hyperthyroidism "My pharmacy switched my Tapazole brand (10 years) to the generic methimazole product without telling me. Within 4 days, I was at the same point before my diagnosis (extreme Graves' disease)."
