What's happening

Oxtriphylline is currently affected by 3 active shortage reports 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.

Oxtriphylline is classified under “OTHER SYSTEMIC DRUGS FOR OBSTRUCTIVE AIRWAY DISEASES” (ATC R03DA).

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.
