Ahead of one of the busiest camping and outdoor weekend of the year, medical officials are asking residents who carry an Epipen to check the expiration date. Suppliers of the medication to treat a severe allergic reaction such as a bee sting, say manufacturing issues will impact the amount of Epipens available in the weeks to come.

Health officials are not sending up warning flags yet, but want people to know they might not be able to find a replacement so they're suggesting to keep all Epipens, even if they're expired.

"The active ingredients don't just stop working on the day of the expiry date," explained Kyle Sereda with Moose Jaw and District Paramedics. "The potency is still going to be enough to treat an individual but the longer it goes past the expiry date, the less effective it might be.

And that's why officials are also suggesting a patient calls 9-1-1 after using the expired Epipen. New stock will likely not be available until the end of August although there are still some supplies across the country in varying amounts.
