What's happening

Procainamide is currently affected by 4 active shortage reports filed with Health Canada by ERFA CANADA 2012 INC, APOTEX INC.

The reported causes are: other (please describe in comments); 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.

Procainamide is classified under “ANTIARRHYTHMICS, CLASS I AND III” (ATC C01BA).
