What's happening
Aminophylline is currently affected by 2 active shortage reports filed with Health Canada by OMEGA LABORATORIES LIMITED, OMEGA LABORATORIES LTD.
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.
Health Canada has flagged this as a Tier 3 shortage, its most serious category, meaning the shortage has the greatest potential impact on the health system and alternatives are limited.
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.
Aminophylline is classified under “OTHER SYSTEMIC DRUGS FOR OBSTRUCTIVE AIRWAY DISEASES” (ATC R03DA).
