Table of contents:

Aggrenox is a prescription medication used to lower the risk of stroke in people who have already had a transient ischemic attack (TIA), or a stroke caused by a blood clot. It contains a combination of aspirin and dipyridamole.

Aspirin belongs to a group of drugs called salicylates and dipyridamole is a platelet aggregation inhibitor. Aggrenox works by preventing blood clots from forming. This helps prevent the platelets from forming blood clots, which can lodge in the brain and cause a certain type of stroke (ischemic stroke).

Uses and Dosage

Aggrenox is available in the form of extended-release capsules. Aggrenox regularly at the same times each day to receive the maximum benefit from it. Do not break, crush, or chew the capsules, as doing so can release all the drug at once and increase the risk of side effects. Your dosage is based on your medical condition and response to treatment. If you experience severe headaches when starting this medication, your doctor may temporarily adjust your dose.

The standard dosing for Aggrenox (aspirin/dipyridamole) involves taking one capsule orally twice a day, once in the morning and once in the evening, with or without food. It is recommended to swallow the capsule whole with a full glass of water (8 ounces or 240 milliliters) and avoid crushing or chewing it. Each capsule contains 25mg of aspirin and 200mg of extended-release dipyridamole.
