What's happening

Tazobactam Piperacillin is currently affected by 3 active shortage reports filed with Health Canada by APOTEX INC.

The reported cause is: 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.

Tazobactam Piperacillin is classified under “BETA-LACTAM ANTIBACTERIALS, PENICILLINS” (ATC J01CR).
