What's the recommended aspirin dose for adults?

Dosing depends on why you’re taking it. Here are the common adult dosing ranges:

- Pain or fever (analgesic/antipyretic): 325–650 mg every 4–6 hours as needed. Do not exceed 4,000 mg (4 g) per day without a clinician’s direction.

- Inflammation (prescription use for arthritis, etc.): often 2,000–4,000 mg per day in divided doses (some regimens go higher under medical supervision). The exact dose should be guided by a clinician due to GI and bleeding risks.

- Cardiovascular prevention (low-dose aspirin): typically 75–100 mg daily, most commonly 81 mg. Only use this if a clinician has weighed the benefits and bleeding risk for you.

- Suspected heart attack or stroke: chew 162–325 mg of aspirin right away (unless you’re allergic or have another contraindication), then seek emergency care.

Important safety notes:
- Do not give aspirin to children or teens with viral infections due to risk of Reye’s syndrome.
- Tell your doctor if you have ulcers, bleeding disorders, kidney disease, gout, or are on blood thinners, other NSAIDs, or alcohol, as aspirin can increase bleeding risk.
- Pregnant or planning pregnancy: consult your healthcare provider before taking aspirin.

If you have a specific indication (pain vs. heart health) or other health conditions, I can tailor the dosing more precisely.
