What's happening
Clonazepam is currently affected by 5 active shortage reports filed with Health Canada by PRO DOC LIMITEE, APOTEX INC, TEVA CANADA LIMITED.
The reported causes are: disruption of the manufacture of the drug; shortage of an active ingredient. 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.
Clonazepam is classified under “ANTIEPILEPTICS” (ATC N03AE).
