Privigen may increase the risk of serious and sometimes fatal kidney problems. The risk may be greater if you already have kidney problems. The risk may also be greater if you have diabetes, dehydration or low blood volume, a blood infection, or abnormal proteins in the blood. You may also be at increased risk if you are over 65 years old or if you take another medicine that may harm your kidneys. Contact your doctor right away if you experience decreased urination, lower back or flank pain, swelling or bloating, sudden weight gain, shortness of breath, or weakness.
Privigen 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.
