The reported causes are: demand increase for the drug; delays in manufacturing; manufacturing delays; 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.
Naproxen is classified under “ANTIINFLAMMATORY/ANTIRHEUMATIC PROD.,NON-STEROIDS” (ATC M01AE).
