Common use

Aspirin is a salicylate. It works by reducing substances in the body that cause pain, fever, and inflammation. Aspirin is used to treat pain, and reduce fever or inflammation. It is sometimes used to treat or prevent heart attacks, strokes, and chest pain (angina).

Dosage and direction

Take aspirin exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Take with food if aspirin upsets your stomach. Do not crush, chew, break, or open an enteric-coated or delayed/extended-release pill. Swallow the pill whole.

Precautions

To make sure this medicine is safe for you, tell your doctor if you have: asthma or seasonal allergies; stomach ulcers; liver disease; kidney disease; a bleeding or blood clotting disorder; gout; or heart disease, high blood pressure, or congestive heart failure.
Taking aspirin during late pregnancy may cause bleeding in the mother or the baby during delivery. Tell your doctor if you are pregnant or plan to become pregnant.

Contraindications

You should not use aspirin if you have a bleeding disorder such as hemophilia, a recent history of stomach or intestinal bleeding, or if you are allergic to an NSAID (non-steroidal anti-inflammatory drug) such as Advil, Motrin, Aleve, Orudis, Indocin, Lodine, Voltaren, Toradol, Mobic, Relafen, Feldene, and others.
