Cetirizine for Allergies: Uses, Side Effects, Warnings, and Dosing Information

Generic Name: Cetirizine for Allergies (cetirizine)

Cetirizine for Allergies Reviews

Zyrtec (cetirizine) "My veterinarian advised me to give my cat half a pill. It seems to help her runny nose and sneezing. The only issue I have using the dissolve tabs is that they tend to fall apart when using a pill splitter. Also, I find that these blister packs are incredibly difficult to open. Not only are they child-proof, they're adult-proof!"


Zyrtec (cetirizine) "One of my favorite oral antihistamines, I've been switching between a few for a while once I build up a tolerance for one and have to use a different one. Overall effective but I wish I could only take it instead of finding out it doesn't work and have to sit in misery for 24 hours until I can take a different one."


Zyrtec (cetirizine) "I found Zyrtec to be largely effective in short bursts."
