Children under age 2
Call your pediatrician for guidance before giving acetaminophen to a child under 2 years of age, and call right away if your child is under three months of age and has a fever.
Children over age 2
For children over the age of 2 years, check the label to see how much medicine to give. If you know your child's weight, use that. If you do not know your child's weight, go by age for the dose amount.
Important medication safety reminders
Keep all medicines out of reach of children.
Use only the dosing device that comes with the product (do not use a household teaspoon). See "How to Use Liquid Medicines for Children."
Never give adult medicines to children.
Always read and follow the instructions on the label.
