cetirizine + mometasone

Cetirizine + mometasone is a combination of two active pharmaceutical ingredients used for the management of allergic conditions, particularly allergic rhinitis. Cetirizine is a second-generation antihistamine that selectively inhibits peripheral histamine H1 receptors, reducing symptoms such as sneezing, itching, and runny nose. Mometasone is a synthetic corticosteroid with potent anti-inflammatory properties; it acts by inhibiting the release of inflammatory mediators in nasal tissues. The combination targets both the histaminergic and inflammatory pathways involved in allergy symptoms. While this specific combination does not appear to be marketed under a unique brand name or fixed-dose product as of June 2025, both drugs are commonly co-prescribed or used together (oral cetirizine with intranasal mometasone) for moderate-to-severe seasonal allergic rhinitis when monotherapy is insufficient[3][9]. Clinical studies suggest that combining an oral antihistamine like cetirizine with an intranasal corticosteroid like mometasone can provide symptom relief comparable to either agent alone[3], though guidelines generally recommend starting with monotherapy.
