What's happening
Eszopiclone is currently affected by an active shortage report filed with Health Canada by MANTRA PHARMA INC.
The reported cause is: delay in shipping 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.

See the reports above; manufacturers must state a reason (most commonly manufacturing disruption or a surge in demand) when filing with Health Canada.
What can my pharmacist do about it?
Often quite a lot: substitute an equivalent product from an unaffected manufacturer, adjust quantities, or in most provinces adapt or renew prescriptions on the spot. Call your pharmacy before visiting, and call 811 for free health advice.

Possible alternatives in the same class
Drugs in the same therapeutic class, best-supplied first. These are not automatic substitutes: only your pharmacist or prescriber can judge whether a switch makes sense for you.
Data reflects reports manufacturers are legally required to file with Health Canada, republished with per-drug aggregation by rxstat. Estimated end dates are supplied by manufacturers and frequently change.
