What's happening

Disopyramide is currently affected by an active shortage report filed with Health Canada by CHEPLAPHARM ARZNEIMITTEL GMBH.

The reported cause is: 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.

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

When will Disopyramide be back in stock in Canada?

Manufacturers have not provided a reliable end date. This page updates automatically as soon as an estimate is filed.

Why is Disopyramide in shortage?

See the reports above; manufacturers must state a reason (most commonly manufacturing disruption or a surge in demand) when filing with Health Canada.

What can my pharmacist do about it?

Often quite a lot: substitute an equivalent product from an unaffected manufacturer, adjust quantities, or in most provinces adapt or renew prescriptions on the spot. Call your pharmacy before visiting, and call 811 for free health advice.
