Thrombolytics are used to treat some people who are having a heart attack. They are typically given in a vein (intravenously, or IV). These drugs dissolve or break up blood clots that are blocking blood flow through a coronary artery. Clots cause most heart attacks.
Thrombolytics are used in the hospital as soon as possible after a heart attack. They work best if they are given within 3 hours of a heart attack.1
Thrombolytics are not an option for everyone. They are not used if you have a high risk of having serious problems, such as severe bleeding.
After a heart attack, thrombolytic medicines help to get blood flowing back to the heart.1
Thrombolytics are given in the hospital. So a person is watched closely for any side effects.
The most common side effect is bleeding inside the body.
Other side effects may include:
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
Thrombolytics are also used to treat blood clots that cause strokes.
