Yes, there can be side effects of using aspirin for stroke prevention. Aspirin is a blood-thinning agent that works by reducing the formation of blood clots, which can help prevent strokes. However, like any medication, it can have side effects.

Common side effects of aspirin include stomach pain, heartburn, and stomach ulcers. In some cases, aspirin can also cause more serious side effects such as bleeding in the stomach, brain, or intestines. This risk is higher in people who take high doses of aspirin or take it for a long time.

Additionally, aspirin can interact with other medications, such as blood thinners, nonsteroidal anti-inflammatory drugs (NSAIDs), and certain antidepressants. These interactions can increase the risk of bleeding and other complications.

It is important to talk to a healthcare provider before starting aspirin therapy for stroke prevention. They can help determine the appropriate dosage and monitor for any potential side effects or interactions.
