What's happening

Rizatriptan is currently affected by 9 active shortage reports filed with Health Canada by MANTRA PHARMA INC, MYLAN PHARMACEUTICALS ULC, NATCO PHARMA (CANADA) INC, NORA PHARMA INC and 3 others.

The reported causes are: delay in shipping of the drug; disruption of the manufacture of the drug; other (please describe in comments). 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.

Rizatriptan is classified under “ANTIMIGRAINE PREPARATIONS” (ATC N02CC).

Common questions

When will Rizatriptan be back in stock in Canada?

The latest manufacturer estimate is Dec 31, 2026. Estimates are self-reported and often slip; this page updates automatically when they change.

Why is Rizatriptan 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.
