Age of child: Do not use ibuprofen in children who are less than 6 months old unless your child's doctor tells you to. This is because it has not been found to be safe in children less than 6 months old. The use of the medicine in children less than 6 months is also not approved by the FDA.

No, infant ibuprofen is usually thicker, and it contains more of the medication in each milliliter of liquid. Many bottles of infant ibuprofen look like children’s ibuprofen, so be careful not to mix them up. Parents often wonder if they can give infants the children’s medication or vice versa.

It’s important to know that "children’s ibuprofen" and "infants’ ibuprofen" suspensions have different concentrations. Infant’s ibuprofen has more medication in every milliliter (mL). For example, if you give a child 5 mL of children’s ibuprofen, you’d give them 100 mg. If you give a child 5 mL of infants’ ibuprofen, it would be 200 mg.

If you have any questions about giving ibuprofen to your child, ask your doctor or pharmacist. Never give this or any other kind of medicine to a child younger than 2 years old without getting a doctor's OK first.
