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.
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.
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.
Before taking aspirin, tell your doctor if you are allergic to any drugs, or if you have:
- 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 have any of these conditions, you may need a dose adjustment or special tests to safely take aspirin.
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).
This medication may be harmful to an unborn baby’s heart, and may also reduce birth weight or have other dangerous effects. Tell your doctor if you are pregnant or plan to become pregnant while you are taking aspirin.
Aspirin can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Do not use any other over-the-counter medication without first asking your doctor or pharmacist. Aspirin is contained in many medicines available over the counter. If you take certain products together you may accidentally take too much aspirin. Read the label of any other medicine you are using to see if it contains aspirin.
Avoid taking an NSAID (non-steroidal anti-inflammatory drug) while you are taking aspirin. NSAIDs include ibuprofen (Motrin, Advil), diclofenac (Voltaren), diflunisal (Dolobid), etodolac (Lodine), flurbiprofen (Ansaid), indomethacin (Indocin), ketoprofen (Orudis), ketorolac (Toradol), mefenamic acid (Ponstel), meloxicam (Mobic), nabumetone (Relafen), naproxen (Aleve, Naprosyn), piroxicam (Feldene), and others.
Avoid drinking alcohol while you are taking aspirin. Alcohol may increase your risk of stomach bleeding.
Avoid taking ibuprofen (Advil, Motrin) if you are taking aspirin to prevent stroke or heart attack. Ibuprofen can 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).
