What's happening

Tinzaparin is currently affected by an active shortage report filed with Health Canada by LEO PHARMA INC.

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.

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.

Tinzaparin is classified under “ANTITHROMBOTIC AGENTS” (ATC B01AB).

Common questions

When will Tinzaparin be back in stock in Canada?

The latest manufacturer estimate is Jun 6, 2026. Estimates are self-reported and often slip; this page updates automatically when they change.

Why is Tinzaparin in shortage?

See the reports above; manufacturers must state a reason (most commonly manufacturing disruption or a surge in demand) when filing with Health Canada.

What can my pharmacist do about it?

Often quite a lot: substitute an equivalent product from an unaffected manufacturer, adjust quantities, or in most provinces adapt or renew prescriptions on the spot. Call your pharmacy before visiting, and call 811 for free health advice.
