Standard Adult Dosage for Advil (Ibuprofen)
For adults and children over 12, the maximum is 1,200 mg of ibuprofen in 24 hours. Take 200-400 mg every 4-6 hours as needed for pain or fever. Do not exceed 6 capsules (200 mg each) or 3 caplets (400 mg each) daily unless directed by a doctor.[1][2]
Children's Dosage by Weight and Age
Dosing depends on weight, not just age. Use the chart on the label or consult a pediatrician:
- Under 24 lbs (6-11 months): Ask a doctor.
- 24-35 lbs (12-23 months): 50 mg every 6-8 hours (max 3 doses/24 hours).
- Up to 95 lbs+ (12 years+): Up to 400 mg every 4-6 hours (max 1,200 mg/24 hours).
Measure with the provided syringe for liquids.[1][2]
What Happens If You Take Too Much?
Exceeding 1,200 mg risks stomach bleeding, heart attack, kidney damage, or liver issues, especially with alcohol, other NSAIDs, or long-term use. Symptoms include nausea, vomiting, drowsiness, or bloody stools—seek emergency help immediately.[1][3]
Differences with Other Pain Relievers
Advil (ibuprofen) is an NSAID; unlike acetaminophen (Tylenol), which maxes at 4,000 mg/day for adults, it irritates the stomach more. Alternating them is common but risky—limit total NSAIDs and check with a doctor.[2][3]
When to Talk to a Doctor
Avoid if you have ulcers, heart disease, high blood pressure, pregnancy (especially third trimester), or asthma triggered by aspirin. Don't use over 10 days for pain or 3 days for fever without advice. Interactions occur with blood thinners, steroids, or lithium.[1][2]
