Tissue plasminogen activator (t-PA)
dissolves blood clots.
Tissue plasminogen activator can be
used to treat some people who are having a
stroke caused by a blood clot (ischemic stroke). It is
given in a vein (intravenously, or IV) and in some cases may be given directly
into an artery.
The medicine works best if it is given right away after
stroke symptoms begin. Strict criteria must be met in order to use the
medicine. The medicine can be used to prevent disability after a stroke.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:

Tissue plasminogen activator
should be given right away after the first symptoms of stroke
start. The person and/or family members need to provide as much information as
possible about what symptoms the person had and when they began. This helps
determine whether giving t-PA would be helpful. If it has been too long since the symptoms started, the medicine is unlikely to benefit the person. Other strict
criteria also must be met before the medicine can be given.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
