What's happening

Tizanidine is currently affected by an active shortage report filed with Health Canada by PALADIN LABS INC.

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.

Tizanidine is classified under “MUSCLE RELAXANTS, CENTRALLY ACTING AGENTS” (ATC M03BX).
