Follow all instructions on the label. If you give medicine to your baby, follow your doctor's advice about what amount to give.
For children younger than 6 months of age, follow what your doctor has told you about the amount to give.
Talk to your doctor before you give medicine to reduce a fever in a baby who is 3 months of age or younger. This is to make sure a young baby's fever is not a sign of a serious illness. The exception is if your baby has just had an immunization. Fevers sometimes occur as a reaction to immunizations. After immunizations, you can give your baby medicine to reduce a fever.
Ibuprofen comes in liquid, tablets, caplets, or concentrated drops. Read and follow all the instructions on the medicine bottle and box carefully before giving your child any medicine. There are different products and strengths for infants and children. The correct dose and timing of the dose are important for the medicine to work well.
Do not alternate ibuprofen and acetaminophen because of the possible risk of overdose. Studies have not shown any more benefit from alternating these medicines.
If you are giving your child ibuprofen for fever or pain, don't also give your child a cold or flu medicine that contains acetaminophen or ibuprofen. Your child could get too much medicine.
