About Cetirizine
Cetirizine is approved in adults and children for the treatment of allergic rhinitis, including seasonal and perennial forms, allergic conjunctivitis and chronic idiopathic urticaria. Canada classifies medications as Schedule I (prescription), II (pharmacist-only OTC), III (open OTC) or unscheduled, with provincial variation. Provincial drug plans cover prescription costs at varying rates.
Mechanism and action
Cetirizine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released by mast cells during allergic responses.
Brands and generics in Canada
In Canada, Cetirizine is typically dispensed as one internationally recognised brand along with their corresponding authorised generics. Canadian pharmacies (Shoppers Drug Mart, Rexall, London Drugs and many independents) are licensed provincially, and pharmacists in several provinces can prescribe for minor ailments. Brand-to-generic substitution is decided by the pharmacist under local Health Canada equivalence rules, and the price difference in CAD is usually substantial.
Online and tele-prescribing access
Online pharmacy is regulated provincially in Canada; cross-border imports are restricted. Tele-prescribing platforms have expanded prescription access since 2020. For Cetirizine specifically, the legal online options in Canada depend on its Rx-or-OTC classification under Health Canada.
