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

Prasugrel keeps your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions. Because of this drug action, prasugrel can make it easier for you to bleed, even from a minor injury. Contact your doctor or seek emergency medical attention if you have bleeding that will not stop.

You may also have bleeding on the inside of your body, such as in your stomach or intestines. Call your doctor at once if you have black or bloody stools, or if you cough up blood or vomit that looks like coffee grounds. These could be signs of bleeding in your digestive tract.

If you need to have any type of surgery or dental work, tell the surgeon or dentist ahead of time that you are using prasugrel. You may need to stop using the medicine for at least 7 days before surgery to prevent excessive bleeding.

NSAIDs include ibuprofen (Motrin, Advil), naproxen (Aleve, Naprosyn), diclofenac (Voltaren), diflunisal (Dolobid), etodolac (Lodine), flurbiprofen (Ansaid), indomethacin (Indocin), ketoprofen (Orudis), ketorolac (Toradol), mefenamic acid (Ponstel), meloxicam (Mobic), nabumetone (Relafen), piroxicam (Feldene), and others.
