“Over-the-counter” (OTC) means you can buy the medicine without a doctor's prescription. This doesn’t mean that OTCs are harmless. Like prescription medicines, OTCs can be dangerous if not taken the right way. Talk with your child's doctor before giving your child any medicine, especially the first time.
All OTC medicines have the same kind of label. The label gives important information about the medicine. It says what it is for, how to use it, what is in it, and what to watch out for. Look on the box or bottle, where it says “Drug Facts.”
Check the chart on the label to see how much medicine to give. If you know your child's weight, use that first. If not, go by age. Check the label to make sure it is safe for infants and toddlers younger than 2 years. If you are not sure, ask your child's doctor.
