What is Effient?
Effient (prasugrel) helps to prevent platelets in your blood from sticking together and forming a blood clot. An unwanted blood clot can occur with certain heart or blood vessel conditions.
Effient is used to prevent blood clots in people with acute coronary syndrome who are undergoing a procedure after a recent heart attack or stroke, and in people with certain disorders of the heart or blood vessels.
Effient may also be used for other purposes not listed in this medication guide.
You should not take Effient if you have any active bleeding such as a stomach ulcer or bleeding in the brain (such as from a head injury), a history of stroke, including TIA ("mini-stroke"), or you are scheduled to have surgery, especially heart bypass surgery (coronary artery bypass graft, or CABG).
Effient increases your risk of bleeding, which can be severe or life-threatening. Call your doctor or seek emergency medical attention if you have bleeding that will not stop, if you have black or bloody stools, or if you cough up blood or vomit that looks like coffee grounds.
You may need to stop using the medicine for a short time before any surgery or dental treatment. Do not stop taking Effient unless your doctor tells you to. Stopping too soon could cause life-threatening medical problems.
While you are taking Effient, do not take NSAIDs (non-steroidal anti-inflammatory drugs) without your doctor's advice. 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.
Before taking this medicine
You should not use Effient if you are allergic to prasugrel, or if you have:
any active bleeding such as a stomach ulcer or bleeding in the brain (such as from a head injury);
a history of stroke, including TIA ("mini-stroke"); or
if you are scheduled to have surgery, especially heart bypass surgery (coronary artery bypass graft, or CABG).
To make sure Effient is safe for you, tell your doctor if you have:
a stomach ulcer;
stomach or intestinal bleeding;
a history of surgery, injury, or medical emergency;
liver or kidney disease;
if you weigh less than 132 pounds;
if you also use other medicines to treat or prevent blood clots; or
if you have ever had a severe allergic reaction to clopidogrel (Plavix) or ticlopidine (Ticlid).
Effient is not expected to be harmful to an unborn baby. However, aspirin is usually given with Effient, and aspirin can cause bleeding when it is taken during the last 3 months of pregnancy. Aspirin can also cause side effects in a newborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether prasugrel passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
How should I take Effient?
Take Effient exactly as it was prescribed for you. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Effient is usually given together with aspirin. Follow your doctor's instructions about how much aspirin to take and for how long.
Effient can be taken with or without food.
Because prasugrel keeps your blood from coagulating (clotting) to prevent unwanted blood clots, Effient can also make it easier for you to bleed, even from a minor injury such as a fall or a bump on the head. Contact your doctor or seek emergency medical attention if you fall or hit your head, or have any bleeding that will not stop.
If you need surgery or dental work, tell the surgeon or dentist ahead of time that you are using Effient. You may need to stop using the medicine for a short time before surgery to prevent excessive bleeding.
Do not stop taking Effient unless your doctor tells you to. If you stop taking this medicine too soon you could have life-threatening medical problems such as a blood clot or a heart attack.
Store at room temperature away from moisture and heat. Keep the tablets in their original container, along with the packet or canister of moisture-absorbing preservative. Keep the bottle tightly closed when not in use.
