Activase is used for:

Treating blood clots in the lungs and improving heart function and survival following a heart attack. Activase may also be used to improve recovery and reduce disability in certain patients who have had a stroke. It may also be used for other conditions as determined by your doctor.

  • you have a stroke and you also have known or suspected bleeding in the head or brain, a history of bleeding in the brain, a recent serious head injury, uncontrolled high blood pressure, low platelet count, high international normalized ratio (INR) or prothrombin time (PT), or a history of bleeding problems, or if you had a seizure at the onset of the stroke
  • you have a stroke and you are taking warfarin, or you have used heparin within the past 48 hours and you currently have a high activated partial thromboplastin time (aPTT)

Contact your doctor or health care provider right away if any of these apply to you.
