Effient® (Ef′-fee-ent)

(prasugrel) tablets

Read this Medication Guide before you start taking Effient and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment.

What is the most important information I should know about Effient?

  • Effient is used to lower your chance of having a heart attack or other serious problems with your heart or blood vessels. But, Effient can cause bleeding, which can be serious, and sometimes lead to death. You should not start to take Effient if it is likely that you will have heart bypass surgery (coronary artery bypass graft surgery or CABG) right away. You have a higher risk of bleeding if you take Effient and then have heart bypass surgery.
  • Do not take Effient if you:
    • currently have abnormal bleeding, such as stomach or intestinal bleeding, or bleeding in your head
    • have had a stroke or “mini-stroke” (also known as transient ischemic attack or TIA)
    • are allergic to prasugrel or any of the ingredients in Effient. See the end of this Medication Guide for a list of ingredients in Effient.
  • Get medical help right away if you think you may be having a stroke or TIA. Symptoms that you may be having a stroke or TIA include:
    • sudden slurring of speech,
    • sudden weakness or numbness in one part of your body,
    • sudden blurry vision, or sudden severe headache.
  • If you have a stroke or TIA while taking Effient, your doctor will probably stop your Effient. Follow your doctor's instructions about stopping Effient. Do not stop taking Effient unless your doctor tells you to.
  • Before having any surgery, you should talk to your doctor about stopping Effient. If possible, Effient should be stopped at least 1 week (7 days) before any surgery, as instructed by the doctor who prescribed Effient for you.

Your risk of bleeding while taking Effient may be higher if you also:

  • have had trauma, such as an accident or surgery
  • have stomach or intestine bleeding that is recent or keeps coming back, or you have a stomach ulcer
  • have severe liver problems
  • have moderate to severe kidney problems
  • weigh less than 132 pounds
  • take other medicines that increase your risk of bleeding, including:
    • warfarin sodium (Coumadin*, Jantoven*)
    • a medicine that contains heparin
    • other medicines to prevent or treat blood clots
    • regular daily use of non-steroidal anti-inflammatory drugs (NSAIDs)

Tell your doctor if you take any of these medicines. Ask your doctor if you are not sure if your medicine is one listed above.

  • Effient increases your risk of bleeding because it lessens the ability of your blood to clot. While you take Effient:
    • you will bruise and bleed more easily
    • you are more likely to have nose bleeds
    • it will take longer for any bleeding to stop
  • Call your doctor right away if you have any of these signs or symptoms of bleeding:
    • unexpected bleeding or bleeding that lasts a long time
    • bleeding that is severe or you cannot control
    • pink or brown urine
    • red or black stool (looks like tar)
    • bruises that happen without a known cause or get larger
    • cough up blood or blood clots
    • vomit blood or your vomit looks like “coffee grounds”
  • Do not stop taking Effient without talking to the doctor who prescribes it for you. People who are treated with angioplasty and have a stent, and stop taking Effient too soon, have a higher risk of a blood clot in the stent, having a heart attack, or dying. If you must stop Effient because of bleeding, your risk of a heart attack may be higher. See “What are the possible side effects of Effient?” for more information about side effects.

What is Effient?

Effient is a prescription medicine used to treat people who:

  • have had a heart attack or severe chest pain that happens when your heart does not get enough oxygen, and
  • have been treated with a procedure called “angioplasty” (also called balloon angioplasty).

Effient is used to lower your chance of having another serious problem with your heart or blood vessels, such as another heart attack, a stroke, blood clots in your stent, or death.

Platelets are blood cells that help with normal blood clotting. Effient helps prevent platelets from sticking together and forming a clot that can block an artery or a stent.

It is not known if Effient is safe and works in children.

What should I tell my doctor before taking Effient?
