What is aspirin?
Aspirin is in a group of drugs called salicylates (sa-LIS-il-ates). It works by reducing substances in the body that cause pain, fever, and inflammation.
Aspirin is used to treat mild to moderate pain, and also to reduce fever or inflammation. Aspirin is sometimes used to treat or prevent heart attacks, strokes, and chest pain (angina). Aspirin should be used for cardiovascular conditions only under the supervision of a doctor.
Aspirin may also be used for other purposes not listed in this medication guide.
What is the most important information I should know about aspirin?
There are many brands and forms of aspirin available and not all brands are listed on this leaflet.
Aspirin should not be given to a child or teenager who has a fever, especially if the child also has flu symptoms or chicken pox. Aspirin can cause a serious and sometimes fatal condition called Reye's syndrome in children.
Stop using this medication and call your doctor at once if you have any symptoms of bleeding in your stomach or intestines. Symptoms include black, bloody, or tarry stools, and coughing up blood or vomit that looks like coffee grounds.
Avoid drinking alcohol while you are taking aspirin. Alcohol may increase your risk of stomach bleeding.

Do not use this medication if you are allergic to aspirin, or if you have:
a recent history of stomach or intestinal bleeding;
a bleeding disorder such as hemophilia; or
an allergy to an NSAID (non-steroidal anti-inflammatory drug) such as Advil, Motrin, Aleve, Orudis, Indocin, Lodine, Voltaren, Toradol, Mobic, Relafen, Feldene, and others.
If you have any of these other conditions, you may need a dose adjustment or special tests to safely take aspirin:
asthma or seasonal allergies;
stomach ulcers;
liver disease;
kidney disease;
a bleeding or blood clotting disorder;
heart disease, high blood pressure, or congestive heart failure;
gout; or
nasal polyps.
If you are taking aspirin to prevent heart attack or stroke, avoid also taking ibuprofen (Advil, Motrin). Ibuprofen may make aspirin less effective in protecting your heart and blood vessels. If you must use both medications, take the ibuprofen at least 8 hours before or 30 minutes after you take the aspirin (non-enteric coated form).
