About Furosemide
Furosemide is approved for the treatment of fluid overload due to heart failure, chronic kidney disease and liver cirrhosis (with or without ascites), as well as for acute pulmonary oedema. 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
Furosemide acts on the thick ascending limb of the loop of Henle in the kidney, where it inhibits the Na+/K+/2Cl- co-transporter (NKCC2).
Brands and generics in Canada
In Canada, Furosemide 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 Furosemide specifically, the legal online options in Canada depend on its Rx-or-OTC classification under Health Canada.
