Children's cetirizine
Children's medicinesAlso known as Children's Zyrtec
Cetirizine is an antihistamine that blocks histamine — the chemical behind your child's sneezing, itchy watery eyes, runny nose, and hives. One dose covers a full day, and it causes much less drowsiness than older allergy medicines like diphenhydramine, though some kids still get a little sleepy. Follow the age guidance on the label, and use the dosing cup or syringe from the box — never a kitchen spoon. One honest note: it treats allergies. It is not a sleep aid, and it shouldn't be used as one.
How to take it
When
Once a day, around the same time. Evening can help if it makes your child a little drowsy.
Food
With or without food — either is fine.
Avoid
Don't combine it with other antihistamines, including diphenhydramine or multi-symptom cold medicines that contain one. And never use it to make a child sleepy.
Age limits
Follow the age guidance on the label — ask the pediatrician before using it in children younger than the label allows. Store it locked and up high; it's flavored to taste good.
Missed a dose?
Give it when you remember, unless it's almost time for the next day's dose — then just skip the missed one. Never give a double dose.
