How Antithyroid Drugs Work

Antithyroid drugs, primarily methimazole and propylthiouracil (PTU), work by blocking the thyroid gland's ability to produce hormones. They essentially put the brakes on the overactive thyroid, allowing hormone levels to return to normal. This process usually takes several weeks to months.

Dosing and Duration

Treatment typically starts with higher doses to quickly control hormone levels, then tapers to a maintenance dose. The standard course lasts 12-18 months, but some patients may need longer treatment. Your doctor will regularly check your thyroid levels and adjust the dose as needed.
Antithyroid drugs, including methimazole and propylthiouracil, are used to manage Graves' disease by inhibiting thyroid hormone production.

Potential Side Effects

While generally safe, antithyroid drugs can have side effects. Common ones include rash, joint pain, and nausea. Rare but serious side effects include liver problems and a decrease in white blood cells. It's crucial to follow up regularly with your doctor and report any unusual symptoms promptly.

FAQs

Can I eventually stop taking the medication?

About 30-50% of patients achieve remission after treatment.

Which drug is better: methimazole or PTU?

Methimazole is generally preferred except in early pregnancy.

Will the drugs cure my Graves' disease?

They control symptoms but don't cure the underlying autoimmune issue.
