What's happening
Ampicillin is currently affected by 5 active shortage reports filed with Health Canada by TEVA CANADA LIMITED, 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.
Ampicillin is classified under “BETA-LACTAM ANTIBACTERIALS, PENICILLINS” (ATC J01CA).
