For Hyperthyroidism "I was diagnosed with Graves’ disease after being in remission for 6 years. I had tachycardia, tremors, slight weight loss, nervousness, and fatigue. After 9 months of 20 mg of methimazole, the symptoms have subsided, T4 and T4 normal, but TSH is almost at 16. Side effects: hair loss (falling out in clumps), extreme fatigue, weight gain, and bloating. My dosage has been lowered to 10 mg since now I am hypothyroid instead of hyperthyroid. Radioactive iodine treatment has been discussed, but I’m not in favor of it. I hope the hair comes back and the weight comes off. I also have leukemia, so this may have affected the Graves’ disease. The medicine does its job, but the side effects are very upsetting to one’s personal appearance and emotional being."

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."
