What dose of Advil (ibuprofen) is typically used for children?
Advil’s active ingredient is ibuprofen. For children, ibuprofen dosing is generally based on the child’s weight (not age). The usual dosing approach is a dose of 10 mg per kg per dose, given every 6 to 8 hours as needed, with a maximum of 40 mg per kg per day.
How do you calculate the dose using a child’s weight?
To calculate a typical ibuprofen dose:
- Find the child’s weight in kilograms (kg).
- Multiply weight (kg) by 10 mg to get the mg per dose.
- Convert mg to the right volume using the concentration on the bottle (children’s ibuprofen liquids come in different strengths, such as 100 mg per 5 mL or 50 mg per 1.25 mL).
If you tell me the child’s weight and the exact Advil/children’s ibuprofen liquid concentration on your bottle (or the tablet/chew strength), I can compute the mg and the mL per dose.
Which “children’s medication” formats are usually covered—liquid, chewables, or tablets?
Pediatric dosing can vary based on the product form and concentration:
- Liquid: dosing is usually given in mL.
- Chewables/tablets: dosing is given by the number of mg per dose.
The mg-per-dose rules above still apply, but the how many mL or how many tablets depends on the product strength printed on your package.
What if the package says a different amount or you have multiple ibuprofen products?
It’s common for caregivers to accidentally use the wrong concentration or to mix dosing instructions from different brands/forms. Always follow the concentration printed on the specific bottle you have and don’t combine dosing from different ibuprofen products.
When should you avoid ibuprofen (Advil) or check with a clinician first?
Avoid or get medical advice before giving ibuprofen if the child has:
- Dehydration from vomiting/diarrhea
- Significant kidney problems
- A history of stomach bleeding/ulcers
- A known allergy to ibuprofen/NSAIDs
- Has been advised not to use NSAIDs
Also use caution if the child is taking other medicines that affect bleeding or kidneys.
How long can you use it for fever or pain?
If you’re using ibuprofen for fever or pain, it’s typically used as needed at the interval on the label (every 6 to 8 hours) and stopped once symptoms improve. If fever lasts more than a few days or pain persists, you should contact a clinician.
Safety caps for repeat dosing
Do not exceed the daily maximum (commonly 40 mg/kg/day) and don’t give more frequently than the interval (typically 6–8 hours).

Quick question so I can give an exact dose
What is your child’s weight (lb or kg) and what does your bottle say for concentration (for example, 100 mg per 5 mL)—and is it liquid, chewables, or tablets?
