About propylthiouracil
Propylthiouracil (PTU) is a medicine that treats an overactive thyroid. It helps to lower the amount of thyroid hormone your body makes.
Used for: PTU treats hyperthyroidism, which is when your thyroid gland makes too much thyroid hormone. It is used for Graves’ disease or toxic multinodular goiter when you cannot take methimazole, or when surgery or radioactive iodine is not a good option for you. PTU can also help control hyperthyroidism symptoms before thyroid surgery or radioactive iodine treatment.
