Pediatric Dosing Chart for Kids Allergy

Different over-the-counter (OTC) allergy symptom relief medicines have different doses, directions, and daily limits. To help ensure children are being given allergy symptom relief medicines appropriately, download and print these dosing charts and keep them wherever you store your medicines.

IMPORTANT: Seek medical attention immediately if your child is experiencing a life-threatening allergic (anaphylactic) reaction. OTC allergy relief medicines are not to be used in this type of situation.

Get their allergy relief medicine dose right. Why?

If a child is given more medicine than the label says, it may increase his or her chance of experiencing serious side effects. To use OTC allergy relief medicines responsibly:

  • Give only the dose directed on the label

  • Wait the right amount of time between doses

  • NEVER give more than the daily limit

  • If allergy symptoms last longer than a few days (described in the following bullets), consult a healthcare professional for advice. It’s possible that the problem may need more attention or a different treatment approach may be needed.

  • For BENADRYL® (diphenhydramine), stop use and ask a doctor if symptoms worsen, last for more than 7 days or if new symptoms occur. Do not give more than the recommended dosage or use for prolonged periods of time except on the advice of a doctor. Never use two diphenhydramine products together, even one taken orally and one applied to the skin.

  • For CLARITIN® (loratadine), prolonged usage should only be on the advice of a doctor. If your child has liver disease, seek the advice of a doctor before using this product. Do not use if allergic to loratadine or any of the ingredients in the product.

  • For REACTINE® (cetirizine), stop use and ask a doctor if symptoms persist, worsen or new symptoms occur. Prolonged use only as directed by a doctor.

  • For AERIUS® (desloratadine), prolonged treatment should only be on the advice of a doctor. Limit treatment to 14 days.

  • Refer to product labelling for complete directions for use, including full warnings and other important information before use.

  • To be sure any over-the-counter allergy medication is right for your child, always read and follow the product labels.
