Common questions
What is Tinzaparin used for?
A low molecular weight heparin used to prevent and treat blood clots.
When will Tinzaparin be back in stock in Canada?
Manufacturers have not provided a reliable end date. This page updates automatically as soon as an estimate is filed.
Why is Tinzaparin in shortage?

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.
