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.
Magnesium is classified under “I.V. SOLUTION ADDITIVES” (ATC B05XA).
