About Sildenafil Citrate
Sildenafil citrate is approved in adult men for the treatment of erectile dysfunction. 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
Sildenafil citrate selectively inhibits phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate in the corpus cavernosum.
Brands and generics in Canada
In Canada, Sildenafil Citrate is typically dispensed as 10 internationally recognised brands 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 Sildenafil Citrate specifically, the legal online options in Canada depend on its Rx-or-OTC classification under Health Canada.
