So, it's very important that you check with your healthcare provider about whether or not aspirin therapy is right for you. If you already are taking low-dose aspirin therapy, check with your healthcare professional before stopping it if you have any questions or concerns.
Aspirin does have a downside. Because it acts on the overall system that affects bleeding, aspirin increases the risk of gastrointestinal bleeding, either from an ulcer or gastritis, and the risk of a rare but dangerous form of stroke caused not by a blood clot, but by bleeding in the brain. This fact, and the lack of strong enough evidence to support a change in labeling, led the U.S. Food and Drug Administration panel in December 2003 to vote against including "primary prevention of heart attack" in the indications for use of aspirin on the medication's label.
