Does advil dosage depend on one's weight?

Short answer: yes, weight matters for ibuprofen (Advil) dosing in children, but for adults it’s usually based on age and standard dose ranges rather than weight.

Details:
- Adults
- Typical OTC dose: 200 mg to 400 mg every 4–6 hours as needed.
- Maximum OTC daily amount: about 1200 mg (do not exceed without a doctor’s guidance).
- Prescription dosing can be higher if a clinician prescribes it.
- Take with food to reduce stomach upset; use the lowest effective dose for the shortest possible time.
- Important cautions: not for people with certain stomach/intestinal ulcers or bleeding, kidney disease, heart disease, high blood pressure, or during late pregnancy; avoid combining with other NSAIDs (like aspirin or naproxen) unless advised by a clinician.

- Children and infants (weight-based dosing)
- Dosing is typically mg per kilogram of body weight.
- Common guideline: 5–10 mg of ibuprofen per kg of body weight per dose, every 6–8 hours as needed.
- Maximum: about 40 mg per kg per day (whichever is lower).
- Do not give to infants under 6 months unless advised by a pediatrician.
- Use the appropriate dropper/syringe or dosing device to measure; use formulations labeled for children.
- Always check the label for the exact product’s dosing, since concentration varies (chewables, suspensions, and tablets differ).

If you want, tell me:
- Is this for an adult or a child? If a child, what is their weight and age?
- Any health conditions or other medications (NSAIDs, anticoagulants, kidney disease, pregnancy, etc.)?

I can help you work out a specific, weight-based dose or interpret a product label.
