Urokinase is made from human kidney cells and albumin (part of the blood) and it may contain viruses and other infectious agents that can cause disease. Although donated human blood is screened, tested, and treated to reduce the risk of it containing anything that could cause disease, there is still a small possibility it could transmit disease. Talk with your doctor about the risks and benefits of using this medication.
Urokinase is given as an injection through a needle placed into a vein. You will receive this injection in a clinic or hospital setting.
Urokinase is given slowly, usually over a period of 12 hours, using a continuous infusion pump.Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving urokinase.
Since urokinase is given by a healthcare professional in a clinical setting, you are not likely to miss a dose.
Because urokinase is given in a controlled clinical setting, an overdose is not expected to occur.
Avoid taking aspirin or ibuprofen (Motrin, Advil) to treat a fever shortly after you have received urokinase. These medications can increase your risk of bleeding. Ask your doctor about other methods of treating a fever.
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Tell your caregivers at once if you have a serious side effect such as:
