Aspirin is now commonly used in clinical practice to prevent thrombotic disorders because it has an anti-platelet aggregation effect and can effectively prevent the formation of blood clots. Taking it every other day is not good enough to prevent thrombosis. Adults can effectively prevent blood clots by taking about 100mg of aspirin once a day for only 24 hours. Increasing the dosage each time you take aspirin will not prolong the duration of preventing blood clots, but will only increase the side effects of aspirin. Therefore, it is not recommended to take aspirin every other day to prevent blood clots. For patients with gastritis or peptic ulcers or a tendency to bleed, aspirin should not be taken and drugs such as clopidogrel tablets can be used.
