Zyrtec 10 mg allergy medication

Zyrtec (cetirizine hydrochloride) is a globally recognized second-generation antihistamine used for the treatment of hay fever, allergies, and angioedema. The brand was originally developed and patented by the Belgian biopharmaceutical giant UCB (Union Chimique Belge), which remains the global owner and holder of the original brand rights.

The Polish packaging shown in the image highlights the medication's broad distribution across European markets. While the brand is owned by UCB, the commercialization and marketing of the over-the-counter (OTC) versions in many regions are often handled by consumer health partners, such as Viatris or GSK, while UCB maintains control over the core brand and prescription-strength versions. Manufacturing for the European market typically occurs at UCB's advanced facilities in Switzerland and Italy, though global demand facilitates production across various international sites.
