What is prasugrel?

Prasugrel is used in people who've had a balloon angioplasty to open blocked arteries after having a heart attack or severe chest pain. Prasugrel may help lower your risk of having another heart attack or stroke.

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

Warnings

Prasugrel 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, if you have black or bloody stools, or if you cough up blood or vomit that looks like coffee grounds.

You may need to stop using the medicine for a short time before any surgery or dental treatment. Do not stop taking prasugrel unless your doctor tells you to.

Before taking this medicine

You should not use prasugrel if you are allergic to it, or if you have:

  • active bleeding such as a stomach ulcer or bleeding in the brain (such as from a head injury);

  • a history of stroke, including TIA ("mini-stroke"); or

  • if you are scheduled to have surgery, especially heart bypass surgery (coronary artery bypass graft, or CABG).

Tell your doctor if you have ever had:

  • a stomach ulcer, colon polyps, or diverticulosis;

  • bleeding problems;

  • surgery, an injury, or a medical emergency;

  • liver or kidney disease;

  • if you are allergic to clopidogrel or ticlopidine;

  • if you weigh less than 132 pounds (60 kilograms); or

  • if you also use other medicines to treat or prevent blood clots.

Tell your doctor if you are pregnant or breastfeeding.

How should I take prasugrel?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed. If you also take aspirin, follow your doctor's instructions about how much to take and for how long.

Prasugrel can be taken with or without food.

Swallow the tablet whole and do not crush, chew, or break it.

Because prasugrel keeps your blood from clotting, prasugrel can also make it easier for you to bleed, even from a minor injury. Seek emergency medical attention if you have any bleeding that will not stop.

Tell your doctor if you have a planned surgery or dental work.

Do not stop using prasugrel without your doctor's advice, even if you feel fine. Stopping this medicine too soon may increase your risk of a blood clot, heart attack, or death.

Store at room temperature away from moisture and heat. Keep the tablets in their original container, along with the packet or canister of moisture-absorbing preservative.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking prasugrel?

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

Ask your doctor before taking a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin, ibuprofen, naproxen, Advil, Aleve, Motrin, and others. Using an NSAID with prasugrel may cause you to bruise or bleed easily.

Prasugrel side effects

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

Prasugrel increases your risk of bleeding, which can be severe or life-threatening.

Call your doctor at once if you have:

  • a light-headed feeling, like you might pass out;

  • any bleeding that will not stop;

  • pink or brown urine;

  • signs of a serious blood-clotting problem--pale skin, purple spots under your skin or on your mouth, fever, fast heart rate, weakness, stomach pain, trouble breathing, jaundice (yellowing of the skin or eyes);

  • signs of stomach bleeding--bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds; or

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

The risk of bleeding is higher in older adults.
