You should not take daily low-dose aspirin on your own without talking to your doctor. The risks and benefits vary for each person.

If you have had a heart attack or stroke, your doctor may want you to take a daily low dose of aspirin to help prevent another. Aspirin is part of a well-established treatment plan for patients with a history of heart attack or stroke. Always follow the treatment plans your health care provider has recommended for you.

Because of the risk of bleeding, aspirin therapy is not recommended if you have never had a heart attack or stroke, except for certain carefully selected patients. If you’re over 70, taking aspirin to prevent a first heart attack or stroke could do more harm than good.

Most heart attacks and strokes occur when the blood supply to a part of your heart muscle or brain is blocked. This usually starts with atherosclerosis, a process in which deposits of fatty substances, cholesterol, cellular waste products, calcium and other substances build up in the inner lining of an artery. This buildup is called plaque.

Plaque usually affects large and medium-sized arteries. Plaques can grow large enough to significantly reduce the blood's flow through an artery. But most of the damage occurs when a plaque becomes fragile and ruptures. Plaques that rupture cause blood clots to form that can block blood flow or break off and travel to another part of the body. This is called an embolism.

  • If a blood clot blocks a blood vessel that feeds the heart, it causes a heart attack.
  • If a blood clot blocks a blood vessel that feeds the brain, it causes a stroke.

Aspirin thins the blood, which helps prevent blood clots from forming.

Certain patients will be prescribed aspirin combined with another antiplatelet drug (such as clopidogrel, prasugrel or ticagrelor) – also known as dual antiplatelet therapy (DAPT). Learn more about DAPT.
