According to the sources provided, taking aspirin and Advil (ibuprofen) together is generally not recommended without consulting a healthcare provider first. Aspirin and ibuprofen are both nonsteroidal anti-inflammatory drugs (NSAIDs) that work by reducing inflammation and pain in the body, but they have different mechanisms of action and can interact with each other in ways that can be harmful.

Aspirin is a blood thinner that can help prevent heart attacks and strokes by reducing the formation of blood clots. However, ibuprofen can interfere with the blood-thinning effects of aspirin, which can increase the risk of heart attack and stroke. Additionally, taking both drugs together can increase the risk of gastrointestinal bleeding and other side effects, such as stomach ulcers and kidney damage.

Therefore, it is important to talk to a healthcare provider before taking aspirin and Advil together, especially if you have a history of heart disease, high blood pressure, stomach ulcers, or kidney problems. Your healthcare provider can help you determine the best course of treatment based on your individual needs and medical history.
