Among primary headaches, the International Classification of Headache Disorders distinguishes between tension headache the most commonmigraine, Sythesis of asprin cluster headache. Aspirin or other over-the-counter analgesics are widely recognized as effective for the treatment of tension headache. It is most effective at stopping migraines when they are first beginning.

However, the study population were at relatively higher risk than those who had never had a heart attack or stroke. Some studies recommend aspirin on a case-by-case basis, [45] [46] while others have suggested the risks of other events, such as gastrointestinal bleeding, were enough to outweigh any potential benefit, and recommended against using aspirin for primary prevention entirely.

Agency for Healthcare Research and Quality guideline recommends that aspirin be taken indefinitely.

Background

This is called dual antiplatelet therapy DAPT. United States and European Union guidelines disagree somewhat about how long, and for what indications this combined therapy should be continued after surgery. Cancer prevention[ edit ] Aspirin is thought to reduce the overall risk of both getting cancer and dying from cancer.

The therapy often lasts for one to two weeks, and is rarely indicated for longer periods. After fever and pain have subsided, the aspirin is no longer necessary, since it does not decrease the incidence of heart complications and residual rheumatic heart disease.

Smaller doses are based on these standards, e. In general, for adults, doses are taken four times a day for fever or arthritis, [80] with doses near the maximal daily dose used historically for the treatment of rheumatic fever.

Owing to its effect on the stomach lining, manufacturers recommend people with peptic ulcersmild diabetesor gastritis seek medical advice before using aspirin. In addition to enteric coating, "buffering" is the other main method companies have used to try to mitigate the problem of gastrointestinal bleeding.

Buffering agents are intended to work by preventing the aspirin from concentrating in the walls of the stomach, although the benefits of buffered aspirin are disputed. Almost any buffering agent used in antacids can be used; Bufferin, for example, uses magnesium oxide.

Other preparations use calcium carbonate. Taking equal doses of vitamin C and aspirin may decrease the amount of stomach damage that occurs compared to taking aspirin alone.
