What is the safe daily dose of acetylsalicylic acid?

The daily dose of acetylsalicylic acid (aspirin) typically ranges from 75 mg to 325 mg. The dosage depends on a number of factors; for patients at high risk of myocardial infarction or stroke, a low daily dose of aspirin (81–100 mg) is usually recommended; For patients who have previously suffered a heart attack or stroke, or who have angina or have had a coronary artery stent fitted some time ago, taking a low dose of 75–100 mg of aspirin daily can help prevent a repeat heart attack or stroke. This is known as secondary prevention, meaning it can prevent a second heart attack in the future. Furthermore, for people with a lower risk of heart attack, the benefits of taking aspirin daily do not outweigh the risk of bleeding; conversely, the higher the risk of heart attack, the greater the likelihood that the benefits of daily aspirin therapy will outweigh the risk of bleeding. Therefore, it is essential to use it on an individual basis, following a doctor’s advice.
