Propylthiouracil is an antithyroid medicine. Propylthiouracil is used to treat Graves' disease and hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormone. It is also used before thyroid surgery or radioactive iodine treatment in patients who have already been treated with other medicines that did not work well. It works by stopping the thyroid gland from making thyroid hormone. Doctor's prescription is required to use this medicine.

Always take Propylthiouracil as directed by your physician. Follow all directions on your prescription label and read all medication guides or instruction sheets. Propylthiouracil comes as a tablet to take by mouth. It is usually taken three times a day, once every 8 hours. Your doctor may decrease your dose of propylthiouracil once your condition is controlled. Continue to take propylthiouracil even if you feel well. Do not stop taking propylthiouracil without talking to your doctor. Do not take more or less of it or take it more often than prescribed by your doctor.


Always use Propylthiouracil exactly as directed by your doctor.

If you become pregnant while taking propylthiouracil, call your doctor.Your doctor may tell you to take propylthiouracil during the first months of your pregnancy only and then may switch you to methimazole for the rest of your pregnancy.

A very good service for obtaining lower cost medical prescription supplies. Unfortunately my prescription comes from the UK, therefore the time to delivery can take more than a month. Canadian Pharmacy Service does offer the lowest cost available. I highly recommend this company for ordering medical prescriptions from Canada
