Aspirin is a medication that has been used for over a century to treat pain, fever, and inflammation. It is also commonly used to prevent heart attacks and strokes in people who are at high risk. While aspirin is generally safe when used as directed, there are potential side effects that should be considered.

One of the most common side effects of aspirin use is stomach upset, including nausea, vomiting, and stomach pain. In some cases, aspirin can cause ulcers or bleeding in the stomach or intestines. This risk is higher in people who have a history of stomach ulcers or bleeding, or who take aspirin in high doses or for long periods of time [3].

Aspirin can also increase the risk of bleeding in other parts of the body, such as the brain. This risk is higher in people who have a history of bleeding disorders, or who take other medications that increase the risk of bleeding [2].

In rare cases, aspirin can cause an allergic reaction. Symptoms of an allergic reaction may include hives, difficulty breathing, and swelling of the face, lips, tongue, or throat. If you experience any of these symptoms after taking aspirin, seek medical attention immediately [1].

Other potential side effects of aspirin use include ringing in the ears, dizziness, and confusion. These symptoms are more likely to occur in older adults or people who take high doses of aspirin [3].

It is important to talk to your doctor before taking aspirin, especially if you have a history of stomach ulcers or bleeding, or if you are taking other medications that increase the risk of bleeding. Your doctor can help you determine if aspirin is safe and appropriate for you to use.
