Narcan (naloxone hydrochloride) has saved countless lives. But it, unfortunately, won’t reverse a cocaine overdose.
Simply put, cocaine isn’t an opioid, and Narcan is designed to block opioids. This mismatch means it simply has no effect on a cocaine overdose. But in today’s drug supply—where cocaine is increasingly laced with fentanyl—reaching for Narcan anyway could still save a life. Keep reading to learn more.
What Is Narcan? And How Does It Work?
Narcan is the brand name for naloxone, a medication designed to reverse opioid overdoses.
Opioids, such as heroin, fentanyl, oxycodone, and morphine, bind to opioid receptors in the brain and slow the central nervous system to dangerous levels. Sometimes, they even stop breathing altogether. Yet, Narcan works by binding to those same receptors and blocking the opioids’ effects—often restoring normal breathing within two to three minutes.
It’s available as a nasal spray or injection, requires no prescription in most states, and causes no harm if given to someone without opioids in their system. It’s also an emergency measure, with its effects wearing off within 30 to 90 minutes, which is why 911 must always be called even if you’ve already given the individual struggling Narcon.
Does Narcan Work on Cocaine?
No, and the reason comes down to how cocaine works in the brain.
Cocaine is a stimulant, not an opioid. Instead of binding to opioid receptors, it floods the brain with dopamine by blocking its reabsorption, producing an intense but short-lived rush. It speeds up your heart rate, body temperature, and blood pressure, whereas opioids actually slow these things down.
Since Narcan works exclusively on opioid receptors, it has no mechanism to counteract cocaine’s physiological effects. There’s also no equivalent medication for cocaine overdose.
At the end of the day, a cocaine overdose is a medical emergency, and 911 is the only appropriate response. At the same time (and as mentioned above), giving Narcan to someone overdosing on cocaine won’t hurt them. This means that if you’re unsure why someone is overdosing, giving them Narcan is always a smart move.
What Does a Cocaine Overdose Look Like?
When you know the signs of a cocaine overdose, you can act quickly.
A cocaine overdose is characterized by overstimulation, including:
- A racing or irregular heartbeat
- Chest pain
- High blood pressure
- Dangerously elevated body temperature
- Severe agitation or panic
- And in serious cases, seizures or stroke-like symptoms.
The person may be awake and highly distressed, which is very different from the unresponsive, barely-breathing presentation of an opioid overdose.
Should Still Give Narcan Even for a Cocaine Overdose?
The short answer: Yes.
Today’s cocaine supply is frequently contaminated with fentanyl, often without the person using it having any idea. Fentanyl is a synthetic opioid roughly 100 times stronger than morphine. It’s odorless, colorless, and undetectable by sight or smell.
Thus, if someone loses consciousness after using cocaine and is showing signs of slowed or stopped breathing, administer Narcan immediately. You can’t assume only cocaine was involved. Since Narcan won’t harm someone without opioids in their system, there’s no downside; the only risk is in not giving it. Fentanyl test strips, which can detect fentanyl in a drug supply before use, are another valuable harm reduction tool worth having on hand.
What to Do During a Cocaine Overdose
If you believe someone is experiencing a cocaine overdose:
- Call 911 immediately; this is a medical emergency.
- While waiting for help, stay with the person, keep them on their side if they’re vomiting, and don’t leave them alone.
- If they stop breathing and you can’t find a pulse, begin CPR. If you have Narcan and the person has lost consciousness or is showing slowed breathing, administer it (even if you believe only cocaine was involved).
Most states have Good Samaritan laws that protect people who call for help during an overdose from legal consequences. If you’re afraid to call 911, call anyway. The person in front of you—their life is what matters the most in that moment.
