What's happening

Trimethoprim Polymyxin B is currently affected by an active shortage report filed with Health Canada by SANDOZ CANADA INCORPORATED.

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.

Trimethoprim Polymyxin B is classified under “ANTIINFECTIVES” (ATC S01AA).
