Shortage history
Reports by product
What's happening
Fosaprepitant is currently affected by an active shortage report filed with Health Canada by MERCK CANADA INC.
The reported cause is: demand increase for 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.
Fosaprepitant is classified under “ANTIEMETICS AND ANTINAUSEANTS” (ATC A04AD).
