Generic Name: rho(d) immune globulin (human) (roe D i-MUNE GLOB-ue-lin)
Brand Name: WinRho SDF
A small number of people who have used WinRho SDF have experienced a serious and potentially life-threatening reaction (intravascular hemolysis [IVH]) in which a large number of red blood cells are destroyed in their blood stream. In the patients that experienced this reaction, symptoms usually occurred within 4 hours of receiving WinRho SDF, although they may occur at any time. Your doctor's office, hospital, or clinic will monitor you closely for at least 8 hours after you receive WinRho SDF. Lab tests, including urine testing, should be performed before, during, and after you receive WinRho SDF. Contact your doctor right away if you experience back pain; bloody, discolored, or dark urine; decreased urination; fever; shaking chills; shortness of breath; sudden weight gain; or swelling. If you have any questions about WinRho SDF, or intravascular hemolysis (IVH) or its symptoms, contact your health care provider.
WinRho SDF may increase the risk of blood clots. The risk may be increased in older patients, if you will be confined to a bed or chair for a period of time, if you take estrogen products, or if you have certain catheters. The risk may also be increased if you have a condition that may increase your risk of blood clots, thick blood, heart problems, or a history of blood clots. Blood clots can occur if you do not have any of these conditions. Tell your doctor right away if you develop one-sided numbness or weakness; pain, redness, tenderness, warmth or swelling in the arms or legs; change in color of an arm or leg; chest pain or discomfort; shortness of breath; fast heartbeat; or coughing up blood. Discuss any questions or concerns with your doctor.
