Imagine suddenly having difficulty breathing, feeling like you're suffocating with a sharp pain in your chest. This can sometimes be a very dangerous situation. One reason for this is a large blood clot getting stuck in a major blood vessel that supplies blood to the lungs. In medicine, we call this a pulmonary embolism. In this life-threatening situation, a very important and powerful injection called Urokinase is given to quickly dissolve the blood clot and save your life. Let's talk about this today.
Simply put, what is Urokinase?
Urokinase is a thrombolytic drug . To be precise, this drug helps to go to a blood clot that has formed dangerously inside a blood vessel somewhere in our body, dissolve it, and restore blood flow.
This is usually only used in emergencies and serious cases. It is most commonly used to dissolve large blood clots in the lungs (`massive pulmonary embolism`) . This is not a medicine to be used at home, but is only given in a hospital, under the close supervision of doctors and nursing staff.
What are the things you need to tell the doctor before giving him this medicine?
Because Urokinase is a very strong drug, it can be dangerous to use it with certain medical conditions in your body. Therefore, before deciding to give you this drug, you should definitely tell your doctor about the following things, without hiding anything .
Providing this information is essential for your safety, as the main risk of this medication is bleeding.
| Situation to be reported | Why should I inform you? (Simply) |
|---|---|
| Aneurysm, a head injury, or a brain tumor. | In such a situation, there is a very high risk of bleeding in the brain. |
| Bleeding disorders, blood clotting problems. | The medication may cause the bleeding to become uncontrollable. |
| Uncontrolled high blood pressure. | High blood pressure increases the risk of a blood vessel bursting and bleeding. |
| A recent surgery or biopsy. | Surgical wounds can bleed excessively again. |
| Eye complications caused by diabetes (`Diabetic Retinopathy`). | Bleeding from the delicate blood vessels in the eye can cause vision loss. |
| If you are pregnant, trying to get pregnant, or are a breastfeeding mother. | Special care should be taken as this medicine can affect the mother and the baby in the womb. |
| If you have an allergy to urokinase or any other medicine or food. | This is essential to prevent a serious allergic reaction. |
How is this medicine administered to the body?
This is not a medication that you can take home. It is given to you in a hospital through a cannula (injection into a vein) . Your heart rate, blood pressure, and other vital signs will be monitored by the medical team throughout the treatment.
If this medicine is given to children, special care should be taken under the advice of a pediatrician.
What to do if you overdose?
Since this is given in a hospital, the chances of this happening are very low. However, if it does happen, the hospital staff will immediately notify the National Poisons Information Centre at the Colombo National Hospital or the nearest Emergency Treatment Unit (ETU) .
Other medications that may interact with Urokinase
Other medications you are taking can interact with Urokinase and cause dangerous side effects. Therefore, tell your doctor about all the medications you are taking (including vitamins, herbal products, and pain relievers) .
| Do not take Urokinase with this medicine! | |
|---|---|
| Aminocaproic acid | Tranexamic acid |
| Aprotinin | (These are medications given to stop bleeding, so they block the action of Urokinase) |
| Tell your doctor about these as well (you should be careful). | |

| Painkillers (NSAIDs) such as ibuprofen | Supplements like fish oil and Ginkgo |
