What naloxone does
Naloxone, sold as Narcan, reverses an opioid overdose by blocking opioid receptors in the brain, which rapidly restores breathing.
It is safe and non-addictive. It causes no high, has no street value, and is designed to be used by people with no medical training. It is available over the counter as a nasal spray or an auto-injector.
It is short-acting, working for only 30 to 90 minutes, so calling 911 is still essential after giving it. It saves a life in the moment and is not a treatment for addiction.
- What it does

Give the dose, then call 911, because it wears off before the opioid does. Call us afterwards about what comes next.
What Is Naloxone?
Naloxone, often sold under the brand name Narcan, is a medication that reverses the effects of opioid overdose. It works fast to restore normal breathing when someone has taken too much of an opioid drug like heroin or fentanyl.
Narcan is not a controlled substance. It does not cause a high, and it’s not addictive. That’s why it’s safe for use even by people without medical training. Many police officers, firefighters, and family members now carry it. You can buy it over the counter at stores like CVS or Walgreens.
Can Narcan Be Abused?
Narcan has no street value. It doesn’t make you feel high and won’t help with pain relief. If someone without opioids in their system takes Narcan, nothing will happen. Because of this, Narcan is not one of the addictive substances linked to misuse.
Some people worry that having Narcan may increase the risk of overdose. But research shows that giving people access to Narcan saves lives and helps them get help for opioid addiction.

Family Support in Recovery
Addiction affects the entire family. Family members often struggle too. That’s why many treatment centers include family therapy and support groups as part of recovery.
Programs like Narcotics Anonymous also help loved ones understand the recovery process and how to provide support.
Frequently Asked Questions About Narcan (Naloxone)
Can Narcan reverse all overdoses?
No. Narcan only works for opioid overdoses. It won’t help with overdoses from cocaine, alcohol, or other drugs.
Can Narcan treat addiction?
No. Narcan treats opioid overdose, not addiction itself. For full recovery, a person needs long-term addiction treatment and ongoing support.
What if Narcan doesn’t work?
Sometimes, especially with strong opioids like fentanyl, more than one dose is needed. That’s why it’s important to call 911 even if Narcan is used.
What does the drug naloxone do?
Naloxone works by rapidly blocking the effects of opioids on the brain. It restores normal breathing in people experiencing an opioid overdose, making it a lifesaving emergency medication.
What is the difference between naloxone and Narcan?
Naloxone is the active drug that reverses opioid overdoses. Narcan is a brand name for naloxone that is widely available as a nasal spray and auto-injector.
What happens if you give naloxone to someone who doesn’t need it?
If naloxone is given to a person who is not experiencing an opioid overdose, it will not harm them. The medication has no effect on individuals without opioids in their system.
When do you give naloxone?
Naloxone should be administered immediately if someone shows signs of an opioid overdose, such as slow or stopped breathing, pinpoint pupils, or unresponsiveness. Always call 911 after giving a dose.
Why would someone carry Narcan?
Narcan is a critical tool for anyone at risk of opioid overdose, as well as their family members, friends, and first responders. Carrying Narcan ensures quick access during emergencies.
What was Narcan originally used for?
Narcan was originally approved by the FDA to reverse the dangerous respiratory depression caused by opioid overdoses in medical and emergency settings.
Narcan was originally approved by the FDA to reverse the dangerous respiratory depression caused by opioid overdoses in medical and emergency settings.
Narcan usually takes effect within two to three minutes, restoring breathing and consciousness when opioids are present in the body.
Is Narcan the same as morphine?
No, Narcan is not the same as morphine. Morphine is an opioid pain medication, while Narcan is an opioid antagonist that blocks opioid effects.
What happens in an opioid overdose?
During an opioid overdose, breathing slows or stops due to the drug’s effect on the central nervous system. This lack of oxygen can quickly become life-threatening without immediate intervention.
What are the signs of an opioid overdose?
Common signs include pinpoint pupils, slow or stopped breathing, bluish lips or nails, limp body, and loss of consciousness. Recognizing these signs quickly is vital.
How do you manage an opioid overdose?
Management includes administering naloxone immediately, calling 911, performing rescue breathing if necessary, and monitoring the individual until medical professionals arrive.
What is an overdose reversal?
An overdose reversal occurs when naloxone is used to block opioid effects, restore breathing, and prevent death from an opioid overdose.
What is the antidote for overdose?
For opioid overdoses, naloxone is the recognized antidote. It is safe, effective, and widely distributed for emergency use.
How long does it take to recover from an overdose?
Recovery depends on the type of opioid used, how much was taken, and the person’s overall health. Naloxone works quickly, but medical care is essential for full recovery.
How do hospitals reverse overdoses?
In hospitals, naloxone is often given intravenously for rapid effect, and patients are closely monitored. Doctors may also provide oxygen and supportive care to stabilize the patient.
What happens after you use Narcan?
If the person does not wake within two to five minutes, give another dose, and call for emergency medical help either way. Waking up is not the end of it: because naloxone strips the opioids off the receptors, it can bring on withdrawal, with nausea, chills, restlessness, muscle aches, stomach pain, sweating and a rapid heartbeat, and in some cases seizures, hallucinations or irregular heartbeats. The page is blunt about the bigger picture: Narcan is a second chance, not a treatment for addiction, and without ongoing help relapse is likely and so is another overdose.
