What's happening
Entecavir is currently affected by 2 active shortage reports filed with Health Canada by JAMP PHARMA CORPORATION, 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.
Entecavir is classified under “DIRECT ACTING ANTIVIRALS” (ATC J05AF).
