How to Keep an Overdose Victim Alive Until Help Arrives

With substance use and addiction at epidemic levels and the opioid crisis claiming lives across Canada, one of the greatest fears held by family members of drug users is that their loved one will become the next overdose death. Between January 2016 and September 2025, more than 55,000 Canadians died from apparent opioid toxicity, according to the Public Health Agency of Canada. Fentanyl continues to drive the crisis, with 73% of overdose deaths involving fentanyl or fentanyl-related substances such as carfentanil.

Preparation is key if you, a friend, or a family member has a substance abuse disorder. In an emergency drug overdose event, bystanders experience one of three responses. Fight, flight, or freeze. Unprepared bystanders are more likely to flee or freeze, having no idea how to help. Both reactions cost the victim precious time and can turn an overdose event into an overdose death. Being prepared means you can fight to save someone's life.

Do you know what to do if an overdose occurs?

You'll learn:

• Which drug overdose symptoms distinguish opioid emergencies from stimulant crises and why speed of recognition determines survival.
• The three rescue actions (recovery positioning, rescue breathing, and naloxone) that keep a victim alive during the eight-to-twelve-minute wait for paramedics.
• Why an overdose emergency cabinet at home or at work puts life-saving tools within arm's reach when seconds count.
• Surviving an overdose should lead to professional drug overdose treatment that addresses the addiction itself.

How Do You Recognize the Signs of a Drug Overdose?

Even long-time users can overdose under the wrong circumstances. Recognizing drug overdose symptoms quickly is the first step in preventing an overdose death. Different substances produce different warning signs, and telling them apart helps you give paramedics accurate information when you call 911.

Opiates, including heroin, fentanyl, and oxycodone, can cause respiratory depression (slowed or stopped breathing), unconsciousness, blurred vision, blue lips, skin or nails, and a slow or faint pulse. Pinpoint pupils that barely respond to light and a gurgling or snoring sound from a blocked airway are additional red flags.

A cocaine overdose and other stimulant emergencies look very different. Cocaine, crack, speed, and methamphetamine can cause rapid breathing or heartbeat, heart attack, seizure, stroke, or the sensation of skin crawling. Body temperature may spike dangerously high.

Mixed-substance overdoses add another layer of danger. Around 82% of opioid-related deaths also involve other drugs like benzodiazepines, alcohol, or stimulants. When opioids and depressants combine, breathing can stop with almost no warning. When in doubt, treat every unresponsive person as a life-threatening emergency.

For a deeper breakdown of warning indicators across multiple substances, the Canadian Centre for Addictions has a dedicated resource on identifying the signs of overdose.

What Should You Do When You Call 911?

The sooner you call for medical help, the sooner paramedics can provide life-saving assistance in a drug overdose emergency. Once the overdose victim is stabilized, first responders will transport them to the nearest emergency department. The average response time for an ambulance in Canada varies by region, but the widely accepted standard runs between eight and twelve minutes. A lot can happen in that window, which is why getting help on the way immediately matters so much.

Stay at the scene until responders arrive and be truthful in your answers to the paramedic's questions. The Good Samaritan Drug Overdose Act offers protection. Try to stay as calm as possible and describe any drug overdose symptoms the victim is experiencing. Respiratory depression, unconsciousness, shaking, seizures, blue colouring. The more accurate information paramedics have, the better they can assist the victim, so honesty about what was taken is non-negotiable. Police are not going to arrest bystanders to an overdose when those bystanders are acting within the capacity of the Good Samaritan Law.

The Good Samaritan Drug Overdose Act provides legal protection to anyone who calls 911 when they witness or experience an overdose. The Act protects against charges related to simple drug possession, including breaches tied to pre-trial release, probation orders, conditional sentences, and parole. It does not protect against more serious offences like outstanding warrants, drug trafficking, or the production of controlled substances.

How Can You Keep an Overdose Victim Alive Until Paramedics Arrive?

Once medical help is on the way, three actions keep someone alive during those critical minutes.

Recovery Position

Placing an unconscious overdose victim on their side can prevent choking. The recovery position keeps the airway clear if they vomit and prevents choking on the tongue. Bend the top knee forward for stability and tilt the head slightly back. Vomiting is a common side effect of naloxone, so place the person in the recovery position before administering the drug.

CPR and Rescue Breathing

If the person has stopped breathing, begin CPR if you are trained to do so. Once you start CPR, you are legally obligated to continue until paramedics arrive. Even without formal CPR training, rescue breathing can help. Breathe gently into the victim's mouth after checking that the airway is clear of food, vomit, or any other obstruction. Rescue breaths maintain blood oxygen levels and can mean the difference between life and death.

Administer Naloxone

Naloxone, also known as Narcan, can save a life during an opioid overdose. It's an opioid antagonist that temporarily stops the effects of opioid drugs and is available as an injection or nasal spray. In rare cases a person may have an allergy to naloxone, but Health Canada still recommends administering it "as the outcome is likely better than not administering it." Naloxone takes up to five minutes to work and lasts anywhere from 20 to 90 minutes. It will not reverse overdoses from non-opioid drugs, but it won't cause harm if given to someone unconscious from an unknown substance.

Because opioids can last much longer than naloxone, the drug is not a replacement for emergency medical attention. Overdose symptoms may return once naloxone wears off, and a second dose may be needed. Free naloxone kits are available at most Ontario pharmacies without a prescription or health card. The pharmacist will train you on proper use when you pick up the kit.

What Is an Overdose Emergency Cabinet and Should You Have One?

An overdose emergency cabinet is a dedicated storage station for naloxone kits and related rescue supplies, positioned where anyone can reach them in seconds. Think of it like an AED cabinet mounted on a wall. The same logic applies. Speed saves lives when the right tools are already within reach.

Since June 2023, Ontario's Occupational Health and Safety Act requires employers in high-risk workplaces to stock naloxone on site, train designated staff, and keep kits accessible and unexpired. Construction sites, healthcare facilities, food service operations, and retail establishments all fall under this mandate, with at least one kit required for every 50 employees.

But an overdose emergency cabinet doesn't belong only at work. Families living with someone who uses opioids, prescribed or not, benefit from keeping one at home. A clearly marked pouch near the front door or a designated shelf in the medicine cabinet puts rescue within arm's reach. The contents are straightforward.

• Two doses of naloxone (nasal spray or injectable)
• Non-latex gloves
• A pocket breathing barrier
• Written instructions with illustrations
• A card listing 911 and local poison control numbers

Some municipalities now install public overdose emergency stations in community centres, libraries, and shelters. The investment is minimal. The return is measured in lives.

What Mistakes Make a Drug Overdose Emergency Worse?

Bystanders may feel desperate to help someone experiencing an overdose. Good intentions can backfire without the right knowledge. Avoid the following.

• Do not put an overdose victim in water, such as a bathtub or shower to revive them. This can lead to drowning. To keep someone awake, try talking, walking, or gentle shaking.
• Do not inject anything into an overdose victim other than naloxone. Even seemingly harmless substances like saline can make a dangerous emergency even worse.
• Do not use more drugs after receiving naloxone. The victim may feel withdrawal discomfort, but using again can compound the overdose once naloxone wears off.
• Do not skip the ambulance because naloxone appears to be working. Naloxone can wear off before the opioid does, and the person may stop breathing again hours later.
• Do not use multiple substances together. Drugs with overlapping effects accumulate in the body and make overdose far more likely and far harder to reverse.
• Do not leave an overdose victim alone if at all possible. Monitor their breathing, colour, and consciousness until paramedics take over.
• Do not let stigma stop you from calling for help. The Good Samaritan Drug Overdose Act protects you from simple possession charges when you call 911 during an overdose.
• Do not return to your regular dose after a period of reduced or stopped use. Tolerance drops fast. The dose that felt manageable weeks ago can kill after a brief pause.

When Should an Overdose Lead to Professional Drug Overdose Treatment?

Surviving an overdose is a warning that the next one could be fatal. Every overdose increases the risk of death, and the brain damage caused by oxygen deprivation during even a brief episode can last a lifetime.

Preparation is key to staying calm in an emergency. But preparation also means looking beyond the crisis itself. When someone survives an overdose, the conversation about professional drug overdose treatment needs to happen before the next emergency does.

Professional care starts with medical detox, where physicians manage withdrawal safely under round-the-clock supervision. Opioid withdrawal floods the body with agitation, pain, nausea, and intense cravings. Stimulant withdrawal drives severe depression and psychological distress. Attempting detox alone pushes relapse rates dangerously high and puts the individual right back in overdose territory.

At the Canadian Centre for Addictions, private rehab programmes running 30, 45, 60, 75, or 90 days combine medically monitored detox with individual counselling, group therapy, and relapse prevention planning. Our facilities in Port Hope and Cobourg, Ontario, treat addiction alongside co-occurring mental health conditions. With a 95.6% success rate measured through the Rehabilitation Wellness Inventory and lifetime aftercare available to every graduate, recovery doesn't end at discharge.

By taking some time to consider how you would handle an overdose, you can be better prepared to take action should the need arise. And by connecting your loved one with professional drug overdose treatment, you can help ensure the overdose that just happened is the last one.
