What's happening
Timolol Dorzolamide is currently affected by 2 active shortage reports filed with Health Canada by ELVIUM LIFE SCIENCES, APOTEX INC.
The reported causes are: demand increase for the drug; disruption of the manufacture 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.
Timolol Dorzolamide is classified under “ANTIGLAUCOMA PREPARATIONS AND MIOTICS” (ATC S01ED).
