What is cetirizine?

Louise E. Sivak, MD
Pediatrics
Cetirizine is an antihistamine used for seasonal allergies and some other environmental allergies. It is a more recent "cousin" of diphenhydramine (commonly branded as Benadryl). It may cause mild sedation/sleepiness, but marketed as causing much less than older generations of antihistamine. It can be taken daily. It should not be given to children without the express instruction of the child's pediatrician. It must be used with caution and only after your doctor's approval in persons with hypertension or taking any prescription medication.
