Usage of Reteplase

Reteplase is a thrombolytic (THROM-bo-LIT-ik) drug, sometimes called a "clot-busting" drug. It helps your body produce a substance that dissolves unwanted blood clots.

Reteplase is used to improve heart function and prevent congestive heart failure or death in people who have had a heart attack (acute myocardial infarction).

Reteplase may also be used for purposes not listed in this medication guide.

Reteplase side effects

Get emergency medical help if you have signs of an allergic reaction: hives, rash, itching, skin redness; difficult breathing; swelling of your face, lips, tongue, or throat.

Reteplase increases your risk of bleeding, which can be severe or life-threatening. Call your doctor or seek emergency medical attention if you have bleeding that will not stop. Bleeding may occur from a surgical incision, or from the skin where a needle was inserted during a blood test or while receiving injectable medication. You may also have bleeding on the inside of your body, such as in your stomach or intestines, kidneys or bladder, brain, or within the muscles.

Call your doctor at once if you have signs of bleeding inside your body, such as:

easy bruising or bleeding (nosebleeds, bleeding gums, bleeding from a wound, incision, catheter, or needle injection);

bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;

red or pink urine; or

sudden numbness or weakness (especially on one side of the body), sudden severe headache, slurred speech, problems with vision or balance.

Also call your doctor at once if you have:

chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating;

severe headache, blurred vision, pounding in your neck or ears;

swelling, rapid weight gain, little or no urinating;

severe pain in your upper stomach spreading to your back, nausea and vomiting;

darkening or purple discoloration of your fingers or toes;

very slow heartbeats, shortness of breath, feeling light-headed; or

sudden severe back pain, muscle weakness, numbness or loss of feeling in your arms or legs.

Common side effects may include nausea.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
