What's happening

Penicillin G Benzathine is currently affected by an active shortage report filed with Health Canada by PFIZER CANADA ULC.

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.

Health Canada has flagged this as a Tier 3 shortage, its most serious category, meaning the shortage has the greatest potential impact on the health system and alternatives are limited.

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.

Penicillin G Benzathine is classified under “BETA-LACTAM ANTIBACTERIALS, PENICILLINS” (ATC J01CE).
