How much ml of ibuprofen 100mg/5ml liquid should i give my 5 year old daughter?

Weight dependent: The dosing of this medication is generally 10mg/kg or one tsp (100mg) per 22 lb.If you know your child's weight, you can sort this out.

Dose by weight: The dose of Ibuprofen would depend on your daughter's weight (usually 5 to 10 mg for every 2 1/4 pounds of weight). It may also depend on why she is taking it, and if she has other health conditions. I don't recommend Ibuprofen for children who are dehydrated, vomiting, or have any kidney problems as Ibuprofen can cause side effects for these children.
