The recommended starting dosage of methimazole for adults ranges from 5 mg to 20 mg three times daily. This specific dose a person is prescribed will depend on things like the severity of their hyperthyroidism, how they respond to methimazole, and other factors. When treating hyperthyroidism in children, dosing is determined primarily by weight.
The dose of methimazole (Tapazole®) your healthcare provider recommends will vary, depending on a number of factors, including:
- How you respond to this medication
- The severity of your condition
- Your weight (for children)
- Any other medical conditions you may have.
As is always the case, do not adjust your dose unless your healthcare provider specifically tells you to do so.
For treating hyperthyroidism in adults, the starting dose of methimazole may range from 5 mg three times daily to 20 mg three times daily, depending on the severity of the condition. As the hyperthyroidism becomes controlled, your healthcare provider may be able to lower your dosage.
For hyperthyroidism treatment in children, your child's healthcare provider will calculate an appropriate dosage based on your child's weight. Just as with adults, the starting dose is usually higher; your child's healthcare provider will probably lower the methimazole dosage as your child's condition improves.
Some considerations to keep in mind when taking methimazole include the following:
- Methimazole comes in tablet form. It is usually taken three times daily.
- You can take a dose with or without food.
- For the medication to work properly, it must be taken as prescribed.
- If you are unsure about anything related to your dosage or methimazole dosing in general, please talk with your doctor, nurse, or pharmacist.
