What Is Narcan Used For? Purpose, Benefits, and How It Works

An opioid overdose occurs when someone takes too much of an opioid drug, such as heroin, fentanyl, oxycodone, or morphine, causing their breathing and heart rate to slow or stop. Opioid overdoses are different from overdoses caused by other drugs, such as cocaine or methamphetamine, and Narcan is not effective for those substances.

This life-threatening condition can happen accidentally or intentionally and requires immediate medical attention. Narcan is specifically used for opioid overdoses, including those caused by heroin, fentanyl, prescription pain medications, and other opioids. Narcan does not reverse overdoses caused by benzodiazepines or alcohol.

Symptoms of an Opioid Overdose

Common signs of an opioid overdose include:

• Slow, shallow, or stopped breathing

• Breathing problems, such as slow, shallow, or stopped breathing

• Slow heartbeat or irregular pulse

• Unresponsiveness or loss of consciousness

• Pinpoint (very small) pupils

• Pale, cold, or clammy skin

• Bluish lips or fingertips

• Gurgling or choking sounds

Recognizing these symptoms early is critical, as timely intervention can save a life. Narcan should be administered immediately in cases of suspected overdose, especially when breathing problems or a slow heartbeat are present. This is where Narcan plays a vital role—understanding Narcan uses and how it works can make all the difference in responding to an opioid overdose.

What is Narcan?

Narcan is a brand name for naloxone, a life-saving medicine used to rapidly reverse opioid overdose (naloxone Narcan). Prescription opioids carry significant risks, including the potential for overdose, making it crucial to have naloxone available as a life-saving measure. Opioids, such as heroin, fentanyl, and prescription pain medications, can depress the central nervous system and respiratory function, leading to overdose, which can be fatal if not addressed promptly.

Naloxone works by quickly removing opioids from a person’s system, helping to restore normal breathing and consciousness.

What is Narcan Used For?

Narcan is a brand name for the medication naloxone, which is an opioid antagonist. It is used primarily to rapidly reverse the effects of opioid overdose, including respiratory depression, sedation, and unconsciousness. Narcan works by binding to the same receptors in the brain that opioids target, but it does not produce the same effects. Instead, it blocks the action of opioids and can quickly restore normal breathing in someone experiencing an overdose. However, Narcan is ineffective against overdoses caused by other substances such as alcohol, benzodiazepines, cocaine, or other non-opioid drugs.

Here are the primary uses of Narcan (naloxone):

1. Opioid Overdose Reversal: Narcan is used as an emergency treatment for opioid overdoses. It is administered to individuals who have overdosed on opioids such as heroin, fentanyl, oxycodone, morphine, or methadone. Narcan rapidly displaces opioids from their receptors, reversing the effects of the overdose and restoring normal breathing. Note: Narcan is only effective for opioid overdoses and does not work for overdoses involving other drugs, including alcohol, benzodiazepines, or stimulants like cocaine.

2. Preventative Measure: Narcan can also be administered to individuals at risk of experiencing an opioid overdose, such as those with a history of opioid use disorder or those taking high doses of opioids for pain management. Providing Narcan to these individuals, as well as their friends, family members, or caregivers, can potentially save lives in the event of an overdose.

3. First Aid and Emergency Response: Narcan is carried by many first responders, including paramedics, police officers, and firefighters, to administer in cases of suspected opioid overdose. It is also available in many public places, such as schools, community centers, and homeless shelters, to provide immediate assistance in the event of an overdose. Making naloxone accessible to non-medical individuals is crucial for responding quickly in an opioid emergency.

4. Community Distribution Programs: Some regions have implemented community-based naloxone distribution programs to make Narcan more widely available to individuals at risk of opioid overdose. These programs often include training on how to recognize an overdose and administer naloxone effectively.

After administering Narcan, it is essential to call for emergency help and seek emergency medical help immediately, as professional emergency care is needed to ensure the person’s safety and provide further treatment. While naloxone acts quickly, its effects may wear off within 30 to 90 minutes, so ongoing emergency care and monitoring are crucial because opioids or other drugs may remain in the body and cause symptoms to return.

Opioid overdose reversal medication, such as naloxone, may require more than one dose, especially when dealing with fentanyl; fentanyl test strips can help identify the presence of fentanyl, and multiple doses may be needed after the first dose.

Types of Narcan: Including Naloxone Nasal Spray

Using Narcan (naloxone) is relatively straightforward, and the specific instructions may vary based on the formulation (nasal spray, injectable) and brand. Here are general guidelines for using Narcan in its commonly available nasal spray form:

Narcan Nasal Spray:

1. Recognize Signs of Opioid Overdose:

• Identify the signs of opioid overdose, including unconsciousness, unresponsiveness, slow or no breathing, and pinpoint pupils.

2. Call for Emergency Assistance:

• Dial emergency services (911 or local emergency number) immediately to request professional medical assistance.

3. Prepare the Narcan Nasal Spray:

• Remove the Narcan nasal spray from its packaging.

• Hold the device with your thumb on the bottom of the plunger and two fingers on the nozzle.

4. Administer the Narcan Nasal Spray:

• Position the person on their back.

• Tilt their head back slightly, supporting the neck with one hand.

• Gently insert the tip of the nozzle into one nostril until your fingers touch the bottom of the person’s nose.

• Press the plunger firmly to release the spray into the nostril.

5. Administer Second Dose (if available):

• If there is no improvement in 2-3 minutes or if the person’s breathing remains inadequate, administer a second dose in the other nostril using a new Narcan nasal spray, if available.

6. Continue Monitoring:

• Continue to monitor the person’s vital signs and provide any additional doses if necessary while awaiting professional medical help.

It’s important to follow the specific instructions provided with the Narcan product you have, as there may be variations in administration techniques or dosage. Additionally, seek professional medical attention for the person who has overdosed, even if Narcan has been administered successfully, as the effects of Narcan may wear off before the effects of the opioids.

Note: Some individuals may experience a runny nose as a side effect of Narcan administration or as part of opioid withdrawal symptoms. This is one of several possible physical symptoms that can occur after use.

Where Can I Get Narcan?

Narcan is increasingly accessible through pharmacies (often without a prescription), community health centers, local health departments, and reputable online sources. It is also important to check with local pharmacies for the price and availability of Narcan, as they can provide information on cost and potential assistance programs. These providers may offer training, resources, or free distribution to support overdose prevention. Individuals at risk of opioid overdose, as well as their friends and family, are encouraged to carry naloxone and be prepared to use it in an emergency. Being informed and prepared with Narcan can save lives during an opioid emergency.
