ABSTRACT

Propylthiouracil (PTU) is a commonly used anti-thyroid drug in the treatment of hyperthyroidism due to Graves disease. Life-threatening complications such as agranulocytosis may occur during the treatment of PTU. We present a case of hyperthyroidism due to Graves disease who was admitted with the typical signs of agranulocytosis at two months after the initiation of therapy and treated successfully with granulocyte colony stimulating factor.
