limit of aspirin dose for antiplatelet therapy
1 Aspirin may be used in low dose (75-160mg/day) for prevention of heart attack or stroke in patients with risk factors of these conditions including longstanding diabetes, vascular disease (previous heart attack or stroke, or poor circulation to the legs), or angina. 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.
