What's happening
Riluzole is currently affected by an active shortage report filed with Health Canada by MYLAN PHARMACEUTICALS ULC.
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.
Riluzole is classified under “OTHER NERVOUS SYSTEM DRUGS” (ATC N07XX).
