As temperatures begin to drop, health officials are warning British Columbians not to keep naloxone kits in their cars.

The medication, which can reverse a fentanyl overdose, maynot be as effective when it gets cold.

"Lots of people opt to keep their kit in their car so it's handy," said Katie Sokil, a health and wellness advocate at the Living Positive Resource Centre.

"That's not best practice though, just because naloxone is temperature sensitive."

Still work but less effectively

Naloxone that has expired or has been exposed to freezing temperatures is not harmful but may be less effective, according to theProvincial Health Services Authority (PHSA).

"Don't leave naloxone in a car or outside for long periods of time," said thehealth authority's communication officer in an emailed statement.

It doesn't mean naloxone won't work, though.

"You can still use it in an emergency situation," Sokil said.

"But the user should be aware that it may require more doses to resuscitate somebody or reverse an overdose rather than just the standard."

She said it's not clear how much less effective naloxone is when it's been exposed to colder temperatures and the number of additional doses is dependent on the overdose case.

Different brands of naloxone have different temperature thresholds. ThePHSA recommends using kits available from theTake Home Naloxoneprogram.

"If your naloxone is exposed to winter temperatures for extended periods or repeatedly, we advise replacing the ampoules [sealed vials] of naloxone at a Take Home Naloxone site," the health authority said.

Places like the Living Positive Resource Centre in Kelowna, B.C., where Sokil works, and other locations across the province distribute naloxone kits for free. They are also available at pharmacies.

Sokil recommended keeping naloxone in a place with a consistent room temperature, like a purse or backpack.

"We recommend trying to keep it on your person or indoors and away from light and extreme heat or extreme cold," she said.

"In an emergency situation, do use it just know that it might be less effective."

Corrections

  • A previous version of this story said that naloxone kits exposed to temperatures below 5 C should be replaced. In fact, only one brand of naloxone is less effective below 5 C. Health officials say Naloxone that has expired or has been exposed to freezing temperatures is not harmful but may be less effective.
