Methimazole is an antithyroid medication prescribed to manage hyperthyroidism. It works by inhibiting the thyroid gland's production of excess hormones. It may also be used to prepare patients for thyroid surgery or radioactive iodine therapy. Dosage for children is based on weight. Important safety information: Do not use if you are allergic to methimazole, pregnant, or breastfeeding. Inform your doctor of all medical conditions, especially liver disease, blood cell disorders, or a weakened immune system. Methimazole can cause birth defects, so notify your doctor immediately if you become pregnant. Discuss all other medications and supplements you take with your doctor. Take exactly as directed, typically three times daily. Report any weight changes in children to the doctor, and inform any surgeon of your methimazole use before a procedure.

Common side effects can include headache, dizziness, upset stomach, nausea, vomiting, mild rash, itching, hair loss, numbness, tingling, and muscle or joint pain. Notify your doctor if these persist or worsen. Methimazole can suppress bone marrow function, lowering your ability to fight infection and form blood clots. Seek prompt medical attention for signs of infection (fever, chills, sore throat), unusual bleeding, bruising, or pale skin. Also contact your doctor immediately for symptoms of liver problems (nausea, stomach pain, fatigue, loss of appetite, yellowing skin/eyes, dark urine) or an allergic reaction (hives, rash, blistering, difficulty breathing, swelling of the face or throat). This is not a complete list. Always consult your healthcare provider to determine if methimazole is appropriate for you, and report any side effects to them or the FDA.
