Allergy medicine for kids: what the labels allow

Every allergy medicine label sets a minimum age and a child dose. These are for the adult products listed; children's versions (liquids, chewables) have their own labels, so always read the one on the box you buy.

Medicine Youngest age on label Child dose (from the label)
Nasacort 2 Adults and children 12 and over: 2 sprays in each nostril once daily. Once symptoms improve, reduce to 1 spray in each nostril daily.
Flonase 4 Adults and children 12 and over: Week 1: 2 sprays in each nostril once daily. Week 2 through 6 months: 1 or 2 sprays in each nostril once daily, as needed. Ask a doctor about use beyond 6 months of daily use. Children 4 to 11: 1 spray in each nostril once daily, with adult supervision, for the shortest time needed. Ask the child's doctor if needed more than two months a year.

Things to know

  • Nasal steroid sprays carry a label warning that the growth rate of some children may be slower while using them, and ask you to check with the child's doctor if needed more than two months a year.
  • Benadryl's label says excitability may occur, especially in children, and not to use it to make a child sleepy.
  • For a child under the youngest age on the label, the label says ask a doctor or do not use.

This is a summary of labels, not medical advice. Ask your child's doctor or a pharmacist.
