What's happening
Gliclazide is currently affected by 2 active shortage reports filed with Health Canada by SANIS HEALTH INC.
The reported causes are: demand increase for the drug; disruption of the manufacture of the drug. Manufacturers must report shortages, but end-date estimates are their own projections and often move.
If your usual product is affected, a pharmacist is the fastest route to a solution: they can dispense an unaffected manufacturer's equivalent when one exists, and in most provinces can adapt doses or substitute a therapeutic alternative without a new appointment.
Gliclazide is classified under “BLOOD GLUCOSE LOWERING DRUGS, EXCL. INSULINS” (ATC A10BB).
