See full prescribing information for complete boxed warning. This warning does not apply to Rh0 (D)-negative patients treated for the suppression of Rh isoimmunization.
- Intravascular hemolysis (IVH) leading to death has been reported in patients treated for ITP with WinRho SDF.
- IVH can lead to clinically compromising anemia and multi-system organ failure including acute respiratory distress syndrome (ARDS)
- Serious complications including severe anemia, acute renal insufficiency, renal failure and disseminated intravascular coagulation (DIC) have also been reported.
- Closely monitor patients treated with WinRho SDF for ITP in a healthcare setting for at least eight hours after administration (5.2.1). Perform dipstick urinalysis to monitor for hematuria and hemoglobinuria at baseline and 2 hours, 4 hours and prior to the end of the monitoring period. Alert patients and monitor the signs and symptoms of IVH including back pain, shaking chills, fever, and discolored urine or hematuria. Absence of these signs and/or symptoms of IVH within eight hours do not indicate IVH cannot occur subsequently. Perform post-treatment laboratory tests if signs and/or symptoms of IVH are present or suspected after WinRho SDF administration.
