Advil® (generic ibuprofen) is an over‑the‑counter non‑steroidal anti‑inflammatory drug (NSAID) used for pain, fever, and inflammation.
Below are the typical adult and pediatric dosage limits that are widely used in most countries (e.g., U.S., Canada, U.K.). Always follow the instructions on the product label and consult a healthcare professional if you have any questions or pre‑existing health conditions.
---
1. Adults (≥ 18 years)
| Form | Typical dose per administration | Maximum frequency | Daily maximum (OTC) | Daily maximum (prescribed) |
|----------|------------------------------------|------------------------|-------------------------|---------------------------------|
| 200 mg tablets | 200 mg | Every 4–6 h as needed | 1 200 mg | 2 400 mg (usually ≤ 3 200 mg for short‑term use under physician supervision) |
- Take with food or milk to reduce stomach upset.
- Do not exceed the daily OTC limit of 1 200 mg unless a doctor has specifically prescribed a higher dose.
- The prescribed daily limit (e.g., 2 400 mg) is rarely used for long periods; most clinicians will keep it ≤ 2 400 mg for 3–5 days or less, depending on the condition.

2. Children (1 month–17 years)
Dosing is based on weight (5–10 mg/kg per dose), with an upper limit of 40 mg/kg per day. The table below uses the most common 200 mg or 400 mg liquid/chewable formulations. Always use the dosing device (syringe, cup, or measuring spoon) that comes with the product.
| Age / Weight | Dose per administration | Maximum frequency | Daily maximum |
|------------------|------------------------------|------------------------|-------------------|
| 1–2 years (≈ 10 kg) | 50 mg (¼ liquid cup) | Every 6 h | 200 mg |
| 3–5 years (≈ 15 kg) | 100 mg (½ cup) | Every 6–8 h | 400 mg |
| 6–8 years (≈ 20 kg) | 200 mg | Every 6–8 h | 800 mg |
| 9–11 years (≈ 30 kg) | 200 mg | Every 6–8 h | 800 mg |
| 12–17 years (≈ 50 kg) | 200–400 mg | Every 6–8 h | 1 200–1 600 mg |
- Maximum single dose: 40 mg/kg (no single dose should exceed 600 mg for a child weighing 15 kg).
- Maximum daily dose: 40 mg/kg/day.
Note: Children under 6 months usually receive pediatric ibuprofen only under a doctor’s guidance; many OTC brands recommend against use in that age group.

3. General Safety Tips
- Do not exceed the maximum daily dose even if you feel pain remains.
- Avoid combining with other NSAIDs (e.g., naproxen, aspirin) unless directed by a healthcare professional.
- Use the lowest effective dose for the shortest duration to reduce the risk of stomach ulcers, bleeding, kidney impairment, or cardiovascular events.
- If you have heart disease, high blood pressure, kidney disease, liver disease, ulcers, or a bleeding disorder, check with your provider before taking ibuprofen.
- Pregnancy & lactation: Ibuprofen is usually avoided in the third trimester and can pass into breast milk. Discuss alternatives with a provider.
- Drug interactions: Ibuprofen can interact with ACE inhibitors, diuretics, methotrexate, warfarin, and others.
- Side effects: stomach pain, nausea, dizziness, rash, or shortness of breath. Seek medical attention if any serious reactions occur.
