What the medication is used for

TNKase (tenecteplase) is used in adults to treat acute myocardial infarctions (heart attacks). Treatment should begin as soon as possible after symptoms start.

  • recent trauma
  • high blood pressure

Interactions with this medication

Medications that affect blood clotting may increase the risk of bleeding prior to, during or after therapy with TNKase.

Proper use of this medication

TNKase is given as a single injection into a vein. Your doctor will give TNKase as soon as possible after your chest pain starts.

Usual dose

The doctor calculates your dose of TNKase according to your body weight, with a maximum dose of 50 mg (10,000 units). Acetylsalicylic acid (ASA) and heparin are usually given as part of your treatment.

Overdose

In the event of overdose, there may be an increased risk of bleeding. Any patients receiving greater than the recommended dose should be carefully monitored.

Side effects and what to do about them

Like all medicines, TNKase can have side effects.

The most frequent side effect associated with TNKase is bleeding. Most of the time the bleeding is minor, however sometimes major bleeding can occur requiring blood transfusion or leading to circulation problems. If major bleeding occurs, your doctor will stop any medications that can make bleeding worse. Death or permanent disability can occur in patients who experience stroke or other serious bleeding episodes.

Allergic-type reactions such as swelling of the skin and throat, rash or hives can occur.

Other serious side effects affecting the heart and lungs have been reported among patients receiving TNKase and are often caused by the underlying disease. These effects can be life-threatening and may lead to death.

This is not a complete list of side effects. For any unexpected effects while taking TNKase, contact your doctor or pharmacist.
