Prasugrel can cause significant and sometimes fatal bleeding. Do not use prasugrel in patients with active pathological bleeding or a history of transient ischemic attack or stroke. Risk factors for bleeding include body weight of less than 60 kg, propensity to bleed, and concomitant use of medications that increase the risk of bleeding (eg, warfarin, heparin, fibrinolytics, chronic use of NSAIDs). Prasugrel is not recommended in patients 75 years of age or older, except for high-risk situations (diabetes, history of prior myocardial infarction). Do not start prasugrel in patients likely to undergo urgent CABG, and discontinue at least 7 days prior to any surgery. If possible, manage bleeding without discontinuing prasugrel, as discontinuation in the first few weeks after acute coronary syndrome may increase risk for subsequent cardiovascular events .

Uses For This Medicine
Prasugrel is used to prevent strokes, heart attacks, or other serious problems with your heart or blood vessels. It is given to patients before they have a heart procedure called percutaneous coronary intervention (PCI).
A heart attack or stroke may occur when a blood vessel in the heart or brain is blocked by a blood clot. Prasugrel reduces the chance that a harmful blood clot will form by preventing certain cells in the blood from clumping or sticking together. Prasugrel may also increase the chance for serious bleeding in some people.
Prasugrel is available only with your doctor's prescription.
