For many years, aspirin was commonly advised for numerous adults, particularly older individuals, to help prevent a first heart attack or stroke. However, updated guidance from significant health bodies has changed this advice considerably due to a better understanding of the associated dangers. For most healthy adults, especially those 60 and above without a history of cardiovascular disease (CVD), the potential for serious bleeding often outweighs the limited benefits of a daily aspirin regimen today. Taking it occasionally for minor aches, pains, or fever is generally safe for most adults, provided there are no reasons not to.
The Shift in Medical Guidelines
The re-evaluation of aspirin's role in preventing initial cardiovascular events began in the late 2010s, following important studies like ASPREE, ASCEND, and ARRIVE. These studies showed that for adults without existing CVD, aspirin provided minimal heart benefits but significantly increased the risk of major bleeding incidents.
- For adults 60 and older: Key health advisory groups, such as the U.S. Preventive Services Task Force (USPSTF), now advise against starting daily aspirin for primary CVD prevention. The risk of serious bleeding complications, particularly in the stomach and brain, increases with age and is greater than the potential benefits for this group.
- For adults aged 40 to 59: For those in this age bracket with a 10% or higher chance of developing CVD in the next decade, the decision to start daily aspirin should be made individually, after talking with a doctor. Doctors will assess the patient's risk of bleeding alongside their cardiovascular risk factors, such as high blood pressure, diabetes, and high cholesterol.
Occasional vs. Daily Use of Aspirin
Aspirin's safety largely depends on its usage. It is important to distinguish between using aspirin for short-term symptom relief and taking it daily as a preventive measure.
Occasional Use for Pain or Fever
For most adults, taking an aspirin occasionally for issues like headaches, minor aches, or fever is generally considered safe. Nevertheless, even short-term use carries some risk, especially for those with a history of stomach ulcers or bleeding issues. It is important to follow instructions on the product label and see a doctor if pain or fever lasts for several days.
Daily Use for Cardiovascular Prevention
Daily aspirin is still strongly advised for adults with a history of heart attack, stroke, bypass surgery, or certain other cardiovascular conditions. In these cases, known as "secondary prevention," the benefits of preventing another event usually outweigh the risks. However, this decision must always be made by a healthcare provider. Patients should not stop a daily aspirin regimen without consulting their doctor, as it could raise the risk of a blood clot.
Common Risks and Side Effects
Using aspirin, especially regularly, involves several risks that adults should be aware of. These include:
- Gastrointestinal (GI) Bleeding: Aspirin can irritate the stomach lining and increase the risk of stomach ulcers and bleeding. This risk is higher with regular use, in older adults, or for those with past stomach problems.
- Hemorrhagic Stroke: While daily aspirin can help prevent strokes caused by blood clots, it increases the risk of hemorrhagic stroke, which is caused by bleeding in the brain.
- Kidney Damage: High doses of aspirin can affect blood flow to the kidneys and potentially cause damage, particularly in individuals with existing kidney or liver issues.
- Allergic Reactions: Some people are allergic to aspirin, which can cause symptoms like hives, wheezing, and swelling.
- Drug Interactions: Aspirin can interact with other medications, especially blood thinners and other NSAIDs, increasing the risk of bleeding.
Comparison: Occasional Aspirin vs. Daily Aspirin Regimen
| Feature | Occasional Aspirin Use (e.g., for pain/fever) | Daily Aspirin Regimen (e.g., for heart health) |
|---|---|---|
| Primary Purpose | Relieve minor aches, pains, headaches, and reduce fever. | Prevent blood clots to reduce the risk of a first or recurring heart attack or stroke. |
| Usage | Short-term use as needed. | Taken once daily as prescribed by a doctor. |
| Who is it for? | Most adults without contraindications; short-term use. | Individuals with a history of CVD or those aged 40-59 with a high CVD risk, following a doctor's recommendation. |
| Main Risks | Primarily stomach irritation and bleeding, especially at higher doses or with prolonged use. | Increased risk of serious GI bleeding and hemorrhagic stroke, outweighing benefits for many. |
| Medical Supervision | Not always necessary for occasional, short-term use, but a doctor should be consulted for persistent symptoms. | Always requires a doctor's supervision to weigh individual benefits and risks. |
| Considerations | Avoid if you have aspirin allergy, bleeding ulcers, or a history of GI bleeding. | Should not be started for primary prevention in most adults over 60. |
Who Should Avoid Aspirin?
Some adults should not take aspirin at all due to increased risks. This includes those with a known aspirin allergy, a history of GI bleeding or ulcers, bleeding disorders, or those taking other blood thinners. Adults over 60 with no history of heart attack or stroke should not start daily aspirin for prevention. Anyone having surgery or a dental procedure should inform their doctor, as aspirin may need to be stopped temporarily.
Conclusion
Is it safe for adults to take aspirin? The answer is complex and depends heavily on how it's used. Occasional use for pain or fever is generally safe for most adults without contraindications. However, the guidance for daily aspirin to prevent a first heart attack or stroke has changed significantly, with health groups now recommending against it for most older adults due to increased bleeding risks. Daily aspirin remains vital for those with existing cardiovascular disease but requires a doctor's oversight. Before starting or stopping any aspirin regimen, adults should discuss it with their healthcare provider to determine the best approach for their health.
