What is Urokinase used for?
Urokinase is a thrombolytic drug, sometimes called a “clot-busting” drug. It helps your body produce a substance that dissolves unwanted blood clots.
Urokinase is used to treat blood clots in the lungs.
Urokinase may also be used for purposes not listed in this medication guide.
How should I take Urokinase?
Urokinase is injected into a vein through an IV. A healthcare provider will give you this injection.
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.
After treatment with urokinase, your doctor may prescribe a blood thinner or other medication to help prevent future blood clots. Carefully follow all dosing instructions. These medications can make it easier for you to bleed, even from a minor injury.
How do I store Urokinase?
Urokinase is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Urokinase in the bathroom or the freezer. There may be different brands of Urokinase that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.
You should not flush Urokinase down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
