Tirofiban is used to prevent blood clots or heart attack in people with severe chest pain or other conditions, and in those who are undergoing a procedure called angioplasty (to open blocked arteries).

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

You should not receive tirofiban if you have any active internal bleeding (stomach, intestines, etc), a history of bleeding or blood-clotting disorder, if you have ever had low blood platelets after being treated with tirofiban, or if you have had any type of surgery, injury, or medical emergency within the past 30 days.

Tirofiban is given as an infusion into a vein. A healthcare provider will give you this injection.

While using tirofiban, you may need frequent blood tests.

You should not be treated with tirofiban if you are allergic to it, or if you have:

• any active internal bleeding (stomach, intestines, etc);

• a history of bleeding or blood-clotting disorder;

• if you have ever had low blood platelets after being treated with tirofiban; or

Because you will receive tirofiban in a clinical setting, you are not likely to miss a dose.

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

Ask your doctor before taking a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib (Celebrex), diclofenac, indomethacin, meloxicam, and others. Using an NSAID during or shortly after treatment with tirofiban may cause you to bruise or bleed easily.

Avoid activities that may increase your risk of bleeding or injury. Use extra care to prevent bleeding while shaving or brushing your teeth.

Avoid drinking alcohol while receiving tirofiban. Alcohol may increase your risk of bleeding in your stomach or intestines.

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

Tirofiban increases your risk of bleeding, which can be severe or life-threatening. Call your doctor or seek emergency medical attention if you have:

• easy bruising or bleeding (nosebleeds, bleeding gums);

• bleeding around your IV or catheter; or

• any bleeding that will not stop.

You may also have bleeding on the inside of your body, such as in your stomach or intestines. Call your doctor at once if you have bloody or tarry stools, or if you cough up blood or vomit that looks like coffee grounds. These could be signs of bleeding in your digestive tract.
