What's happening

Chlorthalidone is currently affected by an active shortage report filed with Health Canada by APOTEX INC.

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.

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.

Chlorthalidone is classified under “LOW-CEILING DIURETICS, EXCL THIAZIDES” (ATC C03BA).

Common questions

When will Chlorthalidone 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 Chlorthalidone 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.
