Peginterferon Alfa-2a shortage status
Widespread shortage Tier 3: critical
Reports by product
What's happening
Peginterferon Alfa-2a is currently affected by an active shortage report filed with Health Canada by PHARMAAND GMBH.
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.
Peginterferon Alfa-2a is classified under “IMMUNOSTIMULANTS” (ATC L03AB).
