Aspirin’s ability to reduce platelet clumping helps explain why it can prevent some clot-related cardiovascular events—but it can also cause serious bleeding, and it is not right for everyone. Researchers are still investigating other possible roles, including in cancer and preterm birth, without establishing a general preventive benefit for either.

How aspirin can help—and why the effect is not the whole story

Aspirin reduces platelet clumping, which can make it harder for certain clots to form. That antiplatelet action can help prevent some cardiovascular events. But less clotting also means a greater chance of bleeding. The U.S. Food and Drug Administration (FDA) says the mechanism by which aspirin works in treating heart attack and stroke is not completely understood. A known effect on platelets therefore does not mean every mechanism or clinical effect is settled. FDA: Aspirin Questions and Answers

Does a daily low-dose aspirin benefit everyone?

No. Whether taking aspirin regularly to prevent a cardiovascular event makes sense depends on a person’s history, cardiovascular risk and other health factors. The FDA describes established benefit particularly for people with cardiovascular disease or a prior heart attack or stroke. For people without signs of or risk factors for vascular disease, long-term risks may outweigh benefits. Do not start daily aspirin for prevention—or change a prescribed regimen—without discussing it with a health professional.

Prevention after a cardiovascular event

For someone who has had a heart attack or stroke, or has cardiovascular disease, aspirin may be part of a prevention plan. That does not make it suitable for every person in those groups: a clinician needs to weigh the expected benefit against bleeding risk, other conditions and medicines.

Prevention in people without known cardiovascular disease

For someone without a prior event, the potential benefit is less automatic. A person’s risk profile and likelihood of bleeding matter; “low-dose” does not mean risk-free or universally beneficial.

What the ASPREE trial found in healthy older adults

ASPREE studied 19,114 adults aged 65 and older who did not have cardiovascular disease, dementia or disability at enrollment. Aspirin did not improve disability-free survival and increased serious bleeding, according to the National Institute on Aging’s 2025 summary. In an NIH account of the trial published in 2018, 5.9% of participants taking aspirin and 5.2% taking placebo died during the study. Those figures belong to this study population and context; they do not establish what aspirin does for people with prior cardiovascular disease or other groups.

What are aspirin’s benefits and risks?

The central trade-off is between reducing certain clot-related events and increasing the chance of bleeding. The FDA warns that serious adverse effects can include bleeding in the stomach or brain and kidney failure. The balance varies by person, so a clinician should consider both the reason for aspirin use and the individual’s health risks. FDA consumer guidance on aspirin

Conditions and medicines to discuss

Tell a health professional about all medicines and supplements you take and any relevant medical conditions before using aspirin for prevention. FDA guidance identifies aspirin or salicylate allergy, asthma, uncontrolled high blood pressure, severe liver or kidney disease, and bleeding disorders as reasons for caution or avoidance unless a professional has assessed the situation. Ask whether aspirin is appropriate and what dose, if any, to use.

Aspirin in antacid products is a separate concern

Some antacid products for upset stomach or heartburn contain aspirin and can cause stomach or intestinal bleeding, with greater concern for some users. This warning is specifically about aspirin-containing antacid medicines; it is not a blanket instruction to stop a separately prescribed aspirin regimen. FDA Deputy Director Karen Murry said, “We’re focusing on bleeding risk specifically with antacid-aspirin products used to treat upset stomach or heartburn. We’re not telling people to stop taking aspirin altogether.” FDA: Warning: Aspirin-Containing Antacid Medicines Can Cause Bleeding

What other roles are researchers exploring?

Researchers are investigating possible roles for aspirin in certain cancers and preterm birth. These are research directions, not established general preventive recommendations. The available overview does not provide effect estimates, identify a specific group of patients who should use aspirin for these purposes, or establish a current clinical recommendation. Do not treat emerging research as a reason to start aspirin. NIH News in Health: Probing Aspirin’s Benefits: Exploring its Role in Prevention

How to approach aspirin safely

  1. Identify the purpose. Prevention after a cardiovascular event, prevention in someone without a known event, and use for pain or fever are different situations.
  2. Review your health history and medicines. Share relevant conditions, allergies, medicines and supplements with a health professional.
  3. Ask whether aspirin is appropriate and what dose to use. Follow professional guidance rather than choosing a daily regimen on your own.
  4. Check product ingredients. Aspirin can appear in products sold for other purposes, including some antacids. Confirm the active ingredient and dose with a health professional, especially if you already take aspirin.

The FDA’s consumer guidance on suspected acute heart attacks is framed as a question about whether consumers can safely use aspirin to treat them. It is not a substitute for emergency care or individualized advice; seek emergency help if you think you may be having a heart attack.
