What is Cathflo Activase?
Cathflo Activase is used to treat a stroke caused by a blood clot or other obstruction in a blood vessel. This medicine is also used to prevent death from a heart attack (acute myocardial infarction).
Cathflo Activase is also used to treat a blood clot in the lung (pulmonary embolism).
Cathflo Activase is also used to dissolve blood clots that have formed in or around a catheter placed inside a blood vessel. This improve the flow of medicines injected in through the catheter, or blood drawn out through the catheter.
Cathflo Activase may also be used for purposes not listed in this medication guide.
Cathflo Activase increases your risk of severe or fatal bleeding, especially from a surgical incision, or from the skin where a needle was inserted. Seek emergency help if you have any bleeding that will not stop.

active bleeding inside your body;
a brain tumor or aneurysm (dilated blood vessel);
a history of head injury or surgery on your brain or spinal cord within the past 3 months; or
severe or uncontrolled high blood pressure;
a bleeding or blood clotting disorder such as hemophilia;
bleeding inside your brain (if you are receiving Cathflo Activase to treat a stroke); or
a recent history of stroke (if you are receiving Cathflo Activase for pulmonary embolism).
If possible before you receive Cathflo Activase, tell your doctor if you have ever had:
any type of stroke;
bleeding in your brain, stomach, intestines, or urinary tract;
high blood pressure;
an infection of the lining of your heart (also called bacterial endocarditis);
a serious injury or major surgery;
severe bruising or infection around a vein where an IV was placed;

How is Cathflo Activase given?
Cathflo Activase is given as an infusion into a vein. A healthcare provider will give you this injection.
Cathflo Activase is usually given within 3 hours after the first signs of stroke or heart attack symptoms. Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely.
You will also be watched closely for several hours after receiving Cathflo Activase, to make sure you do not have an allergic reaction to the medication.
When used to clear blood clots from a catheter, Cathflo Activase is given in 1 or 2 doses.
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.
What happens if I miss a dose?
Because you will receive Cathflo Activase in a clinical setting, you are not likely to miss a dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.
