Abstract
Hydroxyurea (HU) is frequently used in the treatment of various myeloproliferative neoplasms (MPN) where it reduces cell proliferation by impairing DNA synthesis leading to decreased hematopoiesis. Herein we report a case of a 65-year-old female who was diagnosed with Chronic myeloid leukemia and developed severe hemolytic anemia requiring multiple packed red blood cell (RBC) transfusions while being treated with hydroxyurea. The hemolysis persisted until discontinuation of the drug. Common side-effects of HU like macrocytic anemia, leucopenia, and thrombocytopenia are well known but haemolytic anemia is a rare side-effect, not well known with only a handful of cases being described in the scientific literature so far.
