What's happening

Timolol Dorzolamide is currently affected by an active shortage report filed with Health Canada by ELVIUM LIFE SCIENCES.

The reported cause is: 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.

Timolol Dorzolamide is classified under “ANTIGLAUCOMA PREPARATIONS AND MIOTICS” (ATC S01ED).
