If you carry an EpiPen in the event of a life-threatening allergic reaction, check the expiry date.

An announcement from Pfizer Canada says its adult-dose EpiPen will be in “very limited” supply in pharmacies through August and new stock likely won’t be available until the end of August.

Company representatives say they can provide EpiPen Junior, but supply is limited.

The children and adult auto-injectors are used to deliver an emergency shot of epinephrine to patients who are at risk or have a history of the life-threatening allergic reaction anaphylaxis.

There are no similar alternatives available in Canada.

Health Canada advises anyone who has an anaphylactic reaction but has only an expired EpiPen should use the expired product and immediately call 911.
