What's happening
Omeprazole is currently affected by 10 active shortage reports filed with Health Canada by JAMP PHARMA CORPORATION, APOTEX INC, TEVA CANADA LIMITED, NATCO PHARMA (CANADA) INC and 5 others.
The reported causes are: disruption of the manufacture of the drug; requirements related to complying with good manufacturing practices; the product will be discontinued as of november 16, 2019. 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.
Omeprazole is classified under “DRUGS FOR PEPTIC ULCER AND GASTROESOPHAGEAL REFLUX DISEASE (GERD)” (ATC A02BC).
