Aspirin: Not Just a Harmless OTC Medication
We tend to think of aspirin as a harmless medication. It is dispensed over the counter and is the most widely used OTC medication in the U.S. We take it without thinking we may be exposing ourselves to risks. But in certain situations aspirin can cause dangerous side effects.
What is aspirin, and how does it work?
The chemical name for aspirin is acetylsalicylic acid. It is used to reduce mild pain, inflammation and fever. When you take an aspirin, it blocks the formation of prostaglandins, substances your body creates that are associated with inflammation. Prostaglandins cause inflamed tissues to become red and swollen, but they also serve protective purposes, such as forming a barrier that protects the stomach from the acid it produces to digest your food. That's why long-term aspirin use can sometimes cause stomach bleeding and ulceration or other health problems.
Why do cardiac patients take aspirin?
Another effect of aspirin is to prevent blood platelets from clumping together. Blood platelets are structures in the blood, smaller than white or red blood cells, that aid clotting by sticking together at the site of an injury. This effect of aspirin can cause prolonged bleeding, but it may be beneficial to people who have cardiovascular (from cardio, meaning heart; and vascular, meaning vessel) disease with narrowed blood vessels.
Aspirin can keep blood flowing in the obstructed vessels and thus prevent heart attacks and strokes; but it can also increase the risk for strokes that are caused by bleeding in the brain. Most physicians attempt to lower such risks by asking their patients to keep their daily aspirin consumption to a low dose 81 mg “baby” aspirin.
How does aspirin affect your teeth and gums?
Be sure to let your medical and dental professionals know you are taking aspirin, and how much you take. Also tell us about other OTC medications you take, including herbal medications and supplements, because they may interact with aspirin to cause side effects.
If you have been told to take aspirin because of a cardiac condition or procedure, be sure to follow your recommended treatment. Do not suddenly discontinue aspirin therapy; doing so can increase your risk for heart attack and stroke. Ask us if you should stop taking aspirin before a major dental or oral surgery, but do not stop taking it on your own. We will consult with your physician about your medical condition and let you know our recommendation. In most cases you can continue your aspirin therapy without causing excessive bleeding during the dental procedure.
