If you have hyperthyroidism and experience itching while taking methimazole, stop the medication immediately and seek medical attention. A physician or pharmacist should guide further treatment—you must not self-medicate. If skin itching and rashes persist, discontinue anti-thyroid drug therapy and consider alternative treatments such as radioactive iodine-131 or surgical thyroidectomy. When this occurs, patients should not purchase antipruritic medications on their own to avoid other potential side effects.
