FDA boxed warningBleeding risk
Effient can cause significant, sometimes fatal, bleeding
Do not use Effient in patients with active pathological bleeding or a history of transient ischemic attack (TIA) or stroke
In patients ≥75 years of age, Effient is generally not recommended, because of the increased risk of fatal and intracranial bleeding and uncertain benefit, except in high-risk situations (patients with diabetes or a history of prior myocardial infarction [MI]) where its effect appears to be greater and its use may be considered
Do not start Effient in patients likely to undergo urgent coronary artery bypass graft surgery (CABG). When possible, discontinue Effient at least 7 days prior to any surgery
Additional risk factors for bleeding include: body weight <60 kg, propensity to bleed, concomitant use of medications that increase the risk of bleeding (e.g
., warfarin, heparin, fibrinolytic therapy, chronic use of nonsteroidal anti-inflammatory drugs [NSAIDs])
Suspect bleeding in any patient who is hypotensive and has recently undergone coronary angiography, percutaneous coronary intervention (PCI), CABG, or other surgical procedures in the setting of Effient
If possible, manage bleeding without discontinuing Effient. Discontinuing Effient, particularly in the first few weeks after acute coronary syndrome, increases the risk of subsequent cardiovascular (CV) events

About Effient
Overview
Effient contains prasugrel, an antiplatelet medicine. It is used to reduce the risk of blood clot-related cardiovascular events, including clots in stents, in people with acute coronary syndrome who are being managed with percutaneous coronary intervention (PCI). This includes people with unstable angina or certain types of heart attack. It works by blocking a receptor on platelets, making them less able to become activated and stick together to form clots.
What it treats
Effient is used to reduce the risk of cardiovascular events caused by blood clots, including clots in stents, in patients undergoing percutaneous coronary intervention (PCI) for: - Unstable angina. - Non-ST-elevation myocardial infarction (NSTEMI), a type of heart attack. - ST-elevation myocardial infarction (STEMI), a type of heart attack, with either primary or delayed PCI.
Safety information
Side effects
Bleeding is the most commonly reported side effect of Effient. It can be life-threatening or fatal, and the risk is higher in patients undergoing coronary artery bypass surgery. Other serious reported side effects include thrombotic thrombocytopenic purpura (TTP) and allergic reactions, including angioedema (swelling). Allergic reactions have also occurred in people with a history of allergy to related medicines called thienopyridines. Seek urgent medical attention for serious bleeding or a suspected serious allergic reaction.

When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not take Effient if you have active abnormal bleeding, have ever had a transient ischemic attack (TIA or “mini-stroke”) or stroke, or are allergic to prasugrel or any other ingredient in the medicine. Effient increases the risk of bleeding in people undergoing coronary artery bypass graft (CABG) surgery. Tell your prescriber if you are due to have this surgery or have had an allergic reaction to another thienopyridine medicine. Allergic reactions, including angioedema (swelling beneath the skin), have been reported with Effient. Thrombotic thrombocytopenic purpura (TTP), a condition involving blood clots and low platelet levels, has also been reported. Do not stop Effient without speaking to your prescriber: stopping early increases the risk of a blood clot in a stent, heart attack and death.
Interactions
Opioid medicines can reduce the amount of prasugrel your body is exposed to. Tell your doctor if you take an opioid, as they may consider an injectable antiplatelet medicine.
