Cetirizine is an antihistamine utilized for alleviating allergy symptoms like watery eyes, nasal congestion, itchy eyes/nose, sneezing, hives, and itchiness. Its mechanism involves obstructing a specific natural substance (histamine) produced by the body during allergic responses. However, it does not serve as a preventive measure for hives or manage/treat severe allergic reactions (such as anaphylaxis). If your physician has prescribed epinephrine for addressing allergic reactions, ensure to have your epinephrine injector readily available. Refrain from substituting cetirizine for your epinephrine as directed by your doctor.
