WinRho SDF (Rho(D) Immune Globulin Intravenous (Human): Risk of Intravascular Hemolysis

Cangene, Baxter and FDA notified healthcare professionals that cases of intravascular hemolysis (IVH) and its complications, including fatalities, have been reported in patients treated for immune thrombocytopenic purpura (ITP) with WinRho SDF. IVH can lead to clinically compromising anemia and multi-system organ failure including acute respiratory distress syndrome. Serious complications including severe anemia, acute renal insufficiency, renal failure and disseminated intravascular coagulation have also been reported. Fatal outcomes associated with IVH and its complications have occurred most frequently in patients of advanced age (age over 65) with co-morbid conditions.
