Recommended adult dose for regular strength aspirin

The standard adult dose for regular strength aspirin is 325 mg to 650 mg every 4 hours as needed for pain or fever, not to exceed 3,900 mg in 24 hours. For heart protection or stroke prevention, doctors often recommend a single daily dose of 81 mg to 325 mg.

How long should adults take aspirin at this dose?

Most people use regular strength aspirin for short-term pain or fever relief. Longer use for heart or stroke prevention should follow a doctor’s guidance, since daily aspirin raises bleeding risk over time.

Exceeding 3,900 mg in 24 hours can cause stomach upset, ringing in the ears, or more serious problems such as stomach bleeding and salicylate poisoning. Seek medical help right away if you suspect an overdose.
