What's happening
Thiamine is currently affected by an active shortage report filed with Health Canada by OMEGA LABORATORIES LIMITED.
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.
Thiamine is classified under “VIT B1,PLAIN AND IN COMB WITH VITAMIN B6 AND B12” (ATC A11DA).
