GENERIC NAME: ASPIRIN/DIPYRIDAMOLE SUSTAINED-RELEASE - ORAL (AS-pir-in/DYE-pir-ID-a-mole)
BRAND NAME(S): Aggrenox
USES: This medication is used to reduce the risk of stroke in patients who have had "mini-strokes" (transient ischemic attacks) or a previous stroke due to a blood clot and are at high risk for another stroke. It contains two medications: a very low dose of aspirin (25 milligrams per tablet) and dipyridamole in a slow-release form.Low-dose aspirin and dipyridamole are anti-platelet drugs that work to keep blood flowing to the brain by stopping platelets from clumping together. This helps prevent the platelets from forming blood clots, which can lodge in the brain and cause a certain type of stroke (ischemic stroke).
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking this product and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth as directed by your doctor, with or without food, usually 1 capsule twice a day (morning and evening). Swallow the capsule whole. Do not crush or chew the capsule because this will destroy the slow release of the drug and may increase the risk of side effects.Take this medication with a full glass (8 ounces or 240 milliliters) of water unless your doctor directs you otherwise.Dosage is based on your medical condition and response to treatment. Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day.This capsule is not interchangeable with doses of aspirin and dipyridamole given as separate tablets since the same strength and slow-release dosage form are not available as individual products. Consult your pharmacist for more information.

Related Disease Conditions
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking, or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
Transient Ischemic Attack (TIA, Mini-Stroke)
When a portion of the brain loses blood supply, through a blood clot or embolus, a transient ischemic attack (TIA, mini-stroke) may occur. If the symptoms do not resolve, a stroke most likely has occurred. Learn the symptoms, risk factors, and treatment for a transient ischemic attack.
Fabry disease (Fabry's disease, alpha-galactosidase-A) is a genetic disorder with symptoms such as burning sensations in the hands, small-raised reddish-purplish blemishes on the skin, fever, decreases sweating, and gastrointestinal (GI) difficulties. Fabry disease patients are at increased risk of heart attack, heart disease, kidney failure, and stroke. Symptoms of Fabry disease can be treated with medication.
