Question: how long does it take for baby motrin to kick in?
Answer: Ibuprofen can be given to infants over the age of 6 months and is taken by mouth. The duration of action for ibuprofen is 6-8 hours. Both of these medications begin to work less than one hour after being given to your child. When used as a fever reducer, these medications will take a fever down 1-2 degrees.
