Indications
- Propylthiouracil (PTU) is indicated for the treatment of hyperthyroidism, a condition characterized by an overactive thyroid gland.
- It is prescribed to help reduce the production of thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), in individuals with hyperthyroidism.
- PTU may be used as a temporary treatment to manage hyperthyroidism before undergoing more definitive treatments, such as radioactive iodine therapy or thyroid surgery.
Dosage and administration
- The recommended dosage of PTU for the treatment of hyperthyroidism varies depending on the severity of the condition and individual patient response.
- Typically, the initial dosage of PTU is 100 to 150 milligrams (mg) orally every 8 hours.
- After achieving the desired therapeutic response, the dosage of PTU may be reduced to a maintenance dose of 50 to 100 mg orally every 8 hours.
- It is important to take PTU regularly and at evenly spaced intervals to maintain stable thyroid hormone levels.
- PTU may be taken with or without food, but consistency in administration is key to achieving optimal therapeutic outcomes.
- Follow the dosage instructions provided by your healthcare provider carefully and do not exceed the prescribed dosage without medical supervision.
- If a dose of PTU is missed, take it as soon as remembered, unless it is almost time for the next scheduled dose. Do not double the dose to catch up.
- If you have any questions or concerns about the dosage or administration of PTU, consult your healthcare provider.

Precautions
- Inform your healthcare provider about any history of liver disease, kidney disease, or blood disorders before starting PTU.
- Use caution when taking PTU if you are pregnant, planning to become pregnant, or breastfeeding, as it may affect thyroid function in the developing fetus or newborn.
- Discuss with your healthcare provider if you have any allergies to medications, foods, or other substances before using PTU.
- Be aware that PTU may interact with other medications, so inform your healthcare provider about all medications you are currently taking, including prescription, over-the-counter, and herbal supplements.
- Regular monitoring of thyroid function tests and liver function tests may be necessary while taking PTU to ensure treatment effectiveness and safety.
- If you experience symptoms such as fever, sore throat, unusual bleeding or bruising, or yellowing of the skin or eyes while taking PTU, contact your healthcare provider promptly.
- Keep PTU out of reach of children and pets and store it at room temperature away from moisture and heat sources.
