A low-dose tablet contains 80 milligrams (mg) of aspirin, compared with 325 mg in a regular strength tablet. However, an analysis of data from major studies does not support the use of aspirin as a preventive medicine in people who have not had a heart attack, stroke or heart problems. low-dose tablet contains 80 milligrams (mg) of aspirin, compared with 325 mg in a regular strength tablet.

If you don't have heart disease, the answer is more complex. Don't take aspirin if you are below 45, and think twice about it if you are 79 or older. If you are between 45 and 79, you should consider taking 81 mg of aspirin a day if your risk of heart attack exceeds your risk of aspirin-induced bleeding.
