Aspirin is being studied to determine its effectiveness in treating migraines. So far, studies have been mixed regarding the effectiveness of aspirin as a migraine treatment. Combining caffeine with aspirin appears to have increased benefit in treating migraines. However, aspirin appears to offer less benefit that other medications used to treat migraines.

Recent research suggests that regular use of aspirin or some other nonsteroidal anti-inflammatory drugs (NSAIDs) might help prevent conditions including some cancers, benign prostatic hyperplasia and asthma. Scientists conducting such research generally advise that people not take aspirin for such purposes because of the gastrointestinal and other side effects, but that these potential benefits may be a bonus in people taking aspirin on their physician’s advice for reasons such as relieving arthritis or preventing blood clots.
