Effient can cause severe and sometimes fatal bleeding. It should not be used in patients who have an active bleeding problem or a history of stroke or transient ischemic attack (TIA) ("mini-stroke"). The risk of severe side effects may be increased in patients older than 74 years old. Effient is usually not recommended in these patients, except in certain situations (eg, diabetes, history of heart attack).

Do not use Effient if you will be having bypass heart surgery (coronary artery bypass graft [CABG]). Tell your doctor that you take Effient if you have recently had or will be having any type of surgery. If possible, Effient should be stopped for at least 7 days before surgery.

Tell your doctor if you have risk factors for bleeding, including a body weight of less than 132 lbs (60 kg) or a history of easy or persistent bleeding. Tell your doctor if you take a medicine that may increase your risk of bleeding, such as warfarin, heparin, nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, ibuprofen), or fibrinolytic agents (eg, alteplase).

Tell your doctor if dizziness or fainting occurs while you take Effient. Do not suddenly stop Effient without checking with your doctor. This may increase the risk of severe heart problems or death.


Effient is used for:

Reducing the risk of having another serious heart or blood vessel problem (eg, heart attack, stroke, blood clots in your stent, death). It is intended for use in patients who have had a heart attack, angina, or a procedure called angioplasty.

Effient is a platelet aggregation inhibitor. It works by slowing or stopping platelets from clumping together to form clots.

Do NOT use Effient if:

  • you are allergic to any ingredient in Effient
  • you have an active bleeding problem (eg, ulcer, bleeding in the brain) or a history of stroke or TIA ("mini-stroke")
  • you will be having bypass heart surgery (CABG)

Contact your doctor or health care provider right away if any of these apply to you.
