What's happening
Rizatriptan is currently affected by 8 active shortage reports filed with Health Canada by MYLAN PHARMACEUTICALS ULC, NATCO PHARMA (CANADA) INC, NORA PHARMA INC, JAMP PHARMA CORPORATION and 2 others.
The reported causes are: disruption of the manufacture of the drug; long term back order. 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).
