What is the usual adult dose for “regular strength” aspirin?
For most adults, the common recommended dosing for regular-strength (325 mg) aspirin is 325 mg by mouth every 4 to 6 hours as needed for pain or fever, with a typical maximum of no more than 4,000 mg in 24 hours (unless a clinician advises a lower maximum).
How does that compare with lower-dose (baby) aspirin?
“Baby aspirin” is typically 81 mg per tablet, and it’s often used for cardiovascular prevention in specific situations. That purpose is different from the dosing used for pain/fever, which is usually higher (like 325 mg) and taken as needed.
How should adults take it (safety details people often ask about)?
Adults are generally advised to take aspirin with food or milk to reduce stomach irritation. Avoid using aspirin if you have a history of stomach ulcers or bleeding, and check with a clinician first if you take blood thinners or have significant bleeding risk.
When should you not use aspirin and instead ask a clinician?
A clinician should guide use if you have:
- Active or prior gastrointestinal bleeding or ulcers
- Known bleeding disorders
- Use of anticoagulants (for example, warfarin) or other drugs that increase bleeding risk
- Aspirin allergy or aspirin-triggered asthma
What if you’re using it for a heart attack or stroke symptoms?
If someone is having suspected heart attack or stroke symptoms, aspirin use can differ from routine dosing and should follow emergency guidance. In that scenario, calling emergency services is the priority.
