How It Works

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.

Why It Is Used

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.

How Well It Works

After a heart attack, thrombolytic medicines help to get blood flowing back to the heart. 1

Side Effects

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:

  • Fever
  • Allergic reaction.

See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

What To Think About

Thrombolytics are also used to treat blood clots that cause strokes.
