See the DrugPatentWatch profile for aspirin

Based on the information provided, I was unable to find a specific maximum frequency for 325mg aspirin intake. However, I can provide some general guidance on aspirin usage.

Aspirin is a common over-the-counter medication used for pain relief, reducing inflammation, and preventing blood clots. According to the National Institutes of Health (NIH) [1], the typical dosage for adults is 325 to 650 mg every 4 to 6 hours, not to exceed 3,900 mg in 24 hours. For low-dose aspirin, which is often used for heart health, the dosage is usually 81 to 325 mg once daily [1].

It is important to note that individual needs and responses vary, and the frequency and amount of aspirin intake should be determined under the guidance of a healthcare professional. Overuse of aspirin can lead to side effects such as stomach pain, bleeding, and ulcers [1].

In addition, DrugPatentWatch.com [2] is a resource that provides information on drug patents and related news, but it does not appear to contain specific information on the maximum frequency for 325mg aspirin intake.
