Drug Information



(EMPAVELI) Pegcetacoplan is used to treat a certain blood disorder (paroxysmal nocturnal hemoglobinuria). This disorder causes your body's immune system to destroy red blood cells, which results in anemia. It works by helping block your body's destruction of red blood cells. This effect helps lessen symptoms of anemia (such as tiredness, shortness of breath), and may reduce the need for blood transfusions.
