For Hyperthyroidism "Started on 5 mg and slowly increased to 15 mg. Six months in, I’m heading toward remission and back down to 5 mg. It has made me gain weight that I cannot seem to lose and causes me a lot of fatigue. I’m ready to be off of it, but it’s doing its job, and I didn’t have to kill my thyroid with radioactive iodine."

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)."
