What's happening
Valacyclovir is currently affected by 4 active shortage reports filed with Health Canada by APOTEX INC, MYLAN PHARMACEUTICALS ULC, JAMP PHARMA CORPORATION, BIOMED PHARMA.
The reported causes are: disruption of the manufacture of the drug; delay in shipping 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.
Valacyclovir is classified under “DIRECT ACTING ANTIVIRALS” (ATC J05AB).
