What's happening
Carbamazepine is currently affected by 2 active shortage reports filed with Health Canada by NOVARTIS PHARMACEUTICALS CANADA INC, BIOMED PHARMA.
The reported causes are: demand increase for the drug; dormant. 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.
Carbamazepine is classified under “ANTIEPILEPTICS” (ATC N03AF).
