What's happening
Temozolomide is currently affected by 6 active shortage reports filed with Health Canada by TEVA CANADA LIMITED, MERCK CANADA INC, ACCORD HEALTHCARE INC.
The reported causes are: disruption of the manufacture of the drug; demand increase for 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.
Temozolomide is classified under “ALKYLATINGAGENTS” (ATC L01AX).
