When your child has a fever, you know what it's like to wait it out. Children's Advil works for up to 8 hours with just one dose to reduce fever. This multi symptom liquid Advil for babies temporarily reduces fever and relieves aches and pains due to the common cold, flu, headaches and toothaches (including teething). Active ingredient Ibuprofen (NSAID) is the #1 pediatrician-recommended fever reducer/pain reliever because it reduces fever faster and longer (3). Infants' Advil Drops comes with a syringe for easy dosing; it's also non-staining, dye- and alcohol-free. This Infants' Advil is suitable for children 6-23 months – review all labeled directions and warnings prior to administering to babies.
