Advil and aspirin are both nonsteroidal anti-inflammatory drugs (NSAIDs) that are used to relieve pain and reduce inflammation. However, they work in slightly different ways and have different side effects.
Advil, which is the brand name for ibuprofen, is a nonselective NSAID that works by blocking the production of prostaglandins, which are substances that cause pain and inflammation. It is commonly used to relieve headaches, menstrual cramps, toothaches, and other types of pain [1].
Aspirin, on the other hand, is a nonselective NSAID that works by blocking the production of prostaglandins and thromboxanes, which are substances that cause pain, inflammation, and blood clotting. It is commonly used to relieve pain, reduce fever, and prevent blood clots [2].
While both Advil and aspirin are effective pain relievers, they have different side effects and can interact with other medications differently. Advil can cause stomach upset, heartburn, and other gastrointestinal problems, especially if taken in high doses or for a long period of time. It can also increase the risk of heart attack and stroke, especially in people with a history of heart disease [3].
Aspirin can also cause stomach upset and gastrointestinal problems, but it is more likely to cause bleeding and ulcers in the stomach and intestines, especially if taken in high doses or for a long period of time. It can also increase the risk of bleeding, especially if taken with other blood-thinning medications [2].
In general, it is safe to switch between Advil and aspirin as long as you follow the recommended dosages and do not have any underlying health conditions that may be affected by these medications. However, it is always a good idea to talk to your doctor or pharmacist before switching between medications, especially if you are taking other medications or have any medical conditions [3].
