What's happening
Sildenafil is currently affected by an active shortage report filed with Health Canada by BGP PHARMA ULC.
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.
Sildenafil is classified under “OTHER ANTIHYPERTENSIVES” (ATC C02KX).
