Typical dosage for Methimazole

Your dose depends on whether you’re starting or continuing therapy. Your provider will adjust your continuing dose throughout treatment based on your thyroid hormone levels.

  • Adults: The typical starting dose ranges from 15 mg to 60 mg per day, depending on how severe your hyperthyroidism is. The total daily dose is split into 3 smaller doses that are taken by mouth every 8 hours. Once your thyroid hormone levels become normal, you’ll continue treatment at a maintenance dose that typically ranges from 5 mg to 15 mg taken once a day.

  • Children: The dose will depend on your child’s body weight. The typical starting dose is 0.4 mg/kg of body weight per day. This total dose is split into 3 smaller doses given by mouth every 8 hours. The typical maintenance dose is about half of the starting dose.
