Cetirizine classification?

What is cetirizine, and how is it classified?

Cetirizine is classified as an oral second-generation antihistamine (an H1-receptor antagonist). [1]

Where does it fit among allergy medicines?

As a second-generation, non-sedating–tending antihistamine, cetirizine is commonly used for allergic symptoms such as:
- allergic rhinitis (hay fever)
- urticaria (hives)
- itching associated with allergic skin reactions [1]

Is cetirizine sedating compared with older antihistamines?

Cetirizine is generally considered less sedating than first-generation antihistamines (like diphenhydramine), though drowsiness can still occur in some people. [1]

Does cetirizine act like a “decongestant” or “steroid”?

No. Cetirizine is an antihistamine that blocks H1 receptors. It is not a decongestant and not a corticosteroid. [1]
