FOR STROKES

Most strokes are caused when blood clots move to a blood vessel in the brain and block blood flow to that area. For such strokes (ischemic strokes), thrombolytics can be used to help dissolve the clot quickly. Giving thrombolytics within 3 hours of the first stroke symptoms can help limit stroke damage and disability.

The decision to give the drug is based upon:

A brain CT scan to make sure there is no bleeding
A physical exam that shows a significant stroke
Your medical history

As in heart attacks, a clot-dissolving drug isn't usually given if you have one of the other medical problems listed above.

Thrombolytics are not given to someone who is having a hemorrhagic stroke. They could worsen the stroke by causing increased bleeding.

RISKS

There are various drugs used for thrombolytic therapy, but thrombolytics are used most often. Others drugs include:

Lanoteplase
Reteplase
Staphylokinase
Streptokinase (SK)
Tenecteplase
Urokinase

Hemorrhage or bleeding is the most common risk. It can be life-threatening.

Minor bleeding from the gums or nose can occur in approximately 25% of people who receive the drug. Bleeding into the brain occurs approximately 1% of the time. This risk is the same for both stroke and heart attack patients.

CONTACT A HEALTH CARE PROVIDER OR CALL 911

Heart attacks and strokes are medical emergencies. The sooner treatment with thrombolytics begins, the better the chance for a good outcome.
