What's happening
Spironolactone is currently affected by 6 active shortage reports filed with Health Canada by JAMP PHARMA CORPORATION, MINT PHARMACEUTICALS INC, PFIZER CANADA ULC.
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.
Health Canada has flagged this as a Tier 3 shortage, its most serious category, meaning the shortage has the greatest potential impact on the health system and alternatives are limited.
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.
Spironolactone is classified under “POTASSIUM-SPARING AGENTS” (ATC C03DA).
