Zyrtec Overview

Cetirizine, prominently marketed under the brand name Zyrtec among others, is a potent second-generation antihistamine used in the treatment of hay fever, allergies, angioedema, and urticaria.[5] It acts as a selective antagonist of the histamine H1 receptor.

Oblong white pill, what is it? ## PFIZER 551 is a 10 mg Zyrtec coated tablet manufactured by Pfizer. ## Just found 5 pills matching this description in my new bottle of Xyzal 24 hr.

And you said you found the mystery tablet inside a bottle of Xyzal 24 hr which is also an allergy medication with a similar sounding ingredient (Levocetirizine). These OTC meds can change in appearance, so please let me know what they say. ## Please disregard my message earlier...

white pill 4112

Oblong pill white in color nothing on the other side 4112 ## Hello, Charlie! How are you?

Does anyone else recognize this tablet? ## I have the same thing. I'm trying to figure out I it's my hay-fever meds from Walgreens or some other drugstore.
