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.

1 Aspirin often is prescribed in moderate doses (160-325 mg/day) for patients who are having heart attacks to limit the extent of damage to the heart's muscle (by preventing blood clot formation in the blood vessels of the heart), prevent additional heart attacks, and improve survival. Aspirin often is prescribed in low doses (75-160 mg/day) on a long-term basis to patients with prior heart attacks or strokes and to patients with TIAs (transient ischemic attacks or mini-strokes) and exertional angina to prevent heart attacks and ischemic strokes.
