The FDA approves loratadine for kids as young as two years old, but dosing changes drastically between toddlers and teens. For children 2 to 5 years old, the standard dose is 5 mg once daily—usually in liquid form. Kids 6 and older can take the 10 mg tablet, same as adults.

If your child’s symptoms persist beyond a few weeks, it’s time to look at triggers—dust mites, pet dander, or mold—instead of just treating the reaction.

Side effects are usually mild. Some kids get a dry mouth, upset stomach, or a slight headache. Rarely, there’s increased irritability or trouble sleeping. If your child develops a rash, swelling, or trouble breathing after taking loratadine, stop it immediately and call a doctor—this could be a sign of a serious allergic reaction to the medicine itself.

Cetirizine (Zyrtec) works faster but can cause drowsiness. Diphenhydramine (Benadryl) is strong but short-acting and often too sedating for school-aged kids. Loratadine strikes a balance: long-lasting, gentle, and reliable.
