What's happening
Hydralazine is currently affected by an active shortage report filed with Health Canada by STERIMAX INC.
The reported cause is: other (please describe in comments). 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.
Hydralazine is classified under “ARTERIOLARSMOOTH MUSCLE, AGENTS ACTING ON” (ATC C02DB).
