Common questions

When will Isosorbide Dinitrate 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 Isosorbide Dinitrate 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.
