Chatham-Kent Public Health is warning residents of an increase in drug poisonings and unexpected reactions to substances in the community.
In an alert issued Jan. 29, public health officials said the heightened risk is based on recent opioid-related emergency medical service calls, emergency department visits and suspected drug-related deaths in Chatham-Kent. Partners and people with lived experience have also raised concerns that medetomidine may be present in the local unregulated drug supply.
Medetomidine is a veterinary sedative similar to xylazine, often referred to as “tranq,” but is significantly stronger. Public health officials say its presence increases the risk of overdose and may require multiple doses of naloxone to reverse the effects. The drug can cause profound sleepiness, slowed heart rate, low blood pressure, a very weak or absent pulse and hallucinations. Withdrawal symptoms can begin within hours of last use and may peak within 18 to 36 hours. Medetomidine withdrawal is considered a medical emergency and can require hospitalization.
Public health also noted that prolonged periods of sedation linked to substances like medetomidine can leave people vulnerable to assault, exposure to extreme cold and other environmental dangers.
The alert serves as a reminder that the unregulated drug supply is unpredictable and constantly changing. Officials say substances may not be what users expect, significantly increasing the risk of serious harm or death.
In the event of a suspected overdose, residents are urged to call 911 immediately, administer naloxone if an opioid overdose is suspected, remain with the individual and assist them until paramedics arrive.
Public health officials continue to encourage harm reduction practices, including avoiding using substances alone, checking in with others, being mindful of tolerance and avoiding mixing drugs. They also recommend accessing available supports such as the National Overdose Response Service Safer Consumption Hotline at 1-888-688-6677.
Free naloxone kits are available locally. More information on harm reduction services can be found through CK Public Health.
