What's happening

Atenolol is currently affected by 7 active shortage reports filed with Health Canada by TEVA CANADA LIMITED, APOTEX INC, BIOMED PHARMA.

The reported causes are: disruption of the manufacture of the drug; other (please describe in comments). 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.

Atenolol is classified under “BETA BLOCKING AGENTS” (ATC C07AB).
