Propylthiouracil Medication Information
Propylthiouracil (PTU) is a prescription medication used to treat hyperthyroidism (overactive thyroid). Because it carries a high risk of liver disease, it is typically not the first choice of treatment. Its use is generally reserved for cases in which people are allergic to or cannot tolerate methimazole (Tapazole®), a safer antithyroid medication, or for women in the first trimester of pregnancy. This product comes in tablet form and is usually taken three times a day.
It's wise to review the safety information for propylthiouracil with your healthcare provider before starting treatment with this medication. For example, make sure your healthcare provider is aware of any other health issues you may have, such as a bleeding disorder or liver disease.
