What's happening

Tetrasodium Pyrophosphate is currently affected by 2 active shortage reports filed with Health Canada by CALGARY RADIOPHARMACEUTICAL CENTRE / ALBERTA HEALTH SERVICES, ISOLOGIC INNOVATIVE RADIOPHARMACEUTICALS LTD..

The reported causes are: shortage of an inactive ingredient or component; 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.
