What is naloxone?

Naloxone is a life-saving medication used to reverse an opioid overdose, including overdose related to heroin, fentanyl, or prescription opioid medications. Naloxone is most commonly given in the form of a nasal spray (spray in the nose). Other methods include an injectable (shot) or auto-injector into the outer thigh or another major muscle. Naloxone is safe and easy to use, works almost immediately, and is not addictive. Naloxone has very few negative effects, and has no effect if opioids are not in a person’s system.

Who should carry naloxone?

Anyone c​an carry naloxone, especially: 

  • People who have an opioid use disorder;​
  • People taking opioid medications prescribed by a doctor; 
  • People who use opioids and benzodiazepines together; 
  • People who use drugs; and
  • Anyone who is around people who are in the groups mentioned above.​

California’s Good Samaritan law protects those giving emergency medical care at the scene of a medical emergency, including giving naloxone.​

Why carry naloxone?​​

Naloxone is a life-saving medication that can reverse an opioid overdose. Carrying naloxone provides an extra layer of protection for those at a higher risk for overdose. Although most professional first responders and emergency departments carry naloxone, they may not arrive in time to reverse an opioid overdose. Carry naloxone, use it on someone having an overdose, and potentially save a life.

Bystanders are present at almost half of all fatal overdoses in California. ā€‹Because you cannot use naloxone on yourself, let others know you have it in case you experience an opioid overdose. 

How to recognize an opioid overdose:

Recognizing the signs of an overdose can save a life. Signs of an opioid overdose may include:​

  • Small, constricted ā€œpinpoint pupilsā€
  • Falling asleep or losing consciousness
  • Slow, weak or no breathing
  • Choking or gurgling sounds
  • Limp body
  • Cold and/or clammy skin
  • Discolored skin (especially in lips and nails)

How to respond to an opioid overdose:

It may be hard to tell if someone is experiencing an opioid overdose. If you are not sure, treat it like an opioid overdose—you could save a life. With a fentanyl overdose, two or more doses of naloxone may need to be given.​

  1. Call 911 and give naloxone
  2. Keep the person awake and breathing
  3. Lay the person on their side to prevent choking
  4. Stay with the person until 911 responders arrive

The Naloxone Finder below, from the National Harm Reduction Coalition, provides information on how to locate naloxone in the community. ​​​​​​​​​​​

People who use drugs: mail-based distribution programs

​How do you store and dispose of naloxone?

Naloxone storage

  • Follow manufacturer instructions for storing naloxone. Storage instructions may be different.
  • Keep naloxone in its box until ready for use.
  • Protect from light.
  • Store at room temperature below 77°F (25°C).
  • Do not freeze or expose to heat above 104°F (40°C).
  • Store in a safe location.

Naloxone disposal

Unused naloxone: Dispose of unused naloxone at a local pharmacy or through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. Learn more about safe disposal options​.

Used naloxone:

  • Nasal spray: Put the used naloxone nasal spray back into its box. Dispose of it in solid waste trash.
  • Injectable naloxone: Put the used injectable naloxone back into its original container/box. Used injectable naloxone is considered medical waste and must be disposed of in a sharps disposal bin, such as at a local pharmacy. Do not throw away used injectable naloxone in solid waste trash.

Expired naloxone

Expired naloxone is better than no naloxone: If you have expired or soon-to-expire intranasal or injectable (intramuscular) naloxone that has been properly stored, contact a local syringe services program about donating the naloxone. If you have a large amount (10+ doses), you can contact NEXT Distro about donating the naloxone.

Narcan®​ nasal spray shelf-life extension: The U.S. Food and Drug Administration (FDA) has approved an extended shelf-life for the nasal spray formulation of naloxone (Narcan®​) from two years (24 months) to three years (36 months).​​

Naloxone training

An important part of a naloxone distribution program is to provide training to individuals who may give naloxone. Listed below are training resources:

Laws and regulations

California laws protect persons who give naloxone and make naloxone more readily available.

Good Samaritan Law​

A person cannot be liable for any civil damages that result from providing emergency care, if:

  2. The person provided either emergency medical care or nonmedical care; and
  3. The care was provided at the scene of an emergency.

Drug Overdose Treatment Liability Law

The Drug Overdose Treatment Liability Law eliminates civil and criminal liability for:

  1. Licensed health care providers that prescribe naloxone and issue standing orders for the distribution of naloxone; and
  2. Individuals that administer naloxone to someone suspected of experiencing an overdose after receiving it along with required training.​​
