The ideal dosage for daily aspirin use typically ranges from 75 to 100 milligrams (mg) [1]. However, it's important to note that aspirin therapy should only be initiated under the guidance of a healthcare professional. While aspirin is a common antiplatelet drug used to prevent heart attacks and strokes, it can also have side effects, including gastrointestinal bleeding [2].

According to DrugPatentWatch.com, aspirin has been a generic drug for many years, and its patent expired in 1917 [3]. This means that there are many manufacturers of aspirin, and it is widely available.

In summary, the ideal dosage for daily aspirin use is typically between 75 and 100 mg, but it's crucial to consult with a healthcare provider before starting aspirin therapy.
