Going Home With Naloxone After Residential Treatment: How to Get It in California, Where to Keep It, and the Two-Dose Rule

Most discharge plans from residential treatment cover the big items: aftercare appointments, a sober-living or home arrangement, medications, and a relapse prevention plan. One item is easy to treat as an afterthought, and it should not be: leaving with naloxone, and making sure the people at home know how to use it. This post walks through the logistics in California, how to get it, where to keep it, how the two-dose instruction works, and the household check to run on your first night home.

The Short Version

Naloxone is a medication that can temporarily reverse an opioid overdose, and in March 2023 the U.S. Food and Drug Administration approved 4 mg naloxone nasal spray for sale over the counter, without a prescription. The package directions tell the person responding to call 911, give one spray into one nostril, and, if the person does not respond within 2 to 3 minutes, give a second dose in the other nostril using a new device. Because naloxone can wear off before the opioid does, the person still needs emergency medical care even after they wake up. Anyone leaving residential treatment for an opioid use disorder, or for any substance use where the supply could contain fentanyl, should go home with at least two doses, and at least two other people in the household should know exactly where those doses are kept.

Why the Weeks After Discharge Carry Real Risk

Federal health agencies, including the National Institute on Drug Abuse and the Centers for Disease Control and Prevention, describe several factors that raise overdose risk after a period without opioids. Each one applies directly to someone finishing a residential stay:

• Lost tolerance: After weeks without opioids, the body no longer handles the amount a person used before, so returning to a familiar dose can stop breathing.
• Unknown supply: Fentanyl is now found in pills, powders, and stimulants sold as something else, so a person who never intended to use an opioid can still be exposed to one.
• Using alone: A return to use after treatment is often hidden out of shame, which means no one is in the room to respond.
• Mixing with sedatives: Alcohol and benzodiazepines slow breathing on their own, and combined with opioids the effect compounds.

None of this means a return to use is expected. Many people leave residential care with strong plans and never need naloxone. It means the cost of having it and not needing it is very low, and the cost of needing it and not having it is not.

What We See in Discharge Planning

From my vantage point as a certified addiction counselor and interventionist who sits in on discharge planning, the most common gap is not that the person has no naloxone. It is that the naloxone exists, but only the person in recovery knows where it is. It is in their backpack, their glove box, or a bathroom drawer, and the parent, partner, or roommate who would actually find them has never held the device. In an overdose, the person who needs the naloxone cannot give it to themselves. The plan has to live with the people around them.

The second gap we see is embarrassment on both sides. Families worry that bringing naloxone home signals they expect a relapse. People in recovery worry the same thing. We encourage families to frame it the way they would a fire extinguisher: it is in the kitchen because the house matters, not because anyone plans a fire. Our residential treatment team treats this as a standard part of the discharge conversation rather than a special warning.

How to Get Naloxone in California

There are several routes, and most people can have it in hand the same day:

• Over the counter: Since the 2023 FDA approval, 4 mg nasal spray is sold on pharmacy shelves and at many retail stores without a prescription.
• From a pharmacist: California law allows pharmacists to furnish naloxone directly without a prescription from a doctor, which can matter if you want a different formulation or want to bill insurance.
• Through insurance: Many health plans cover naloxone when a prescription is written. Ask the treatment program’s prescriber whether a prescription can be sent to your pharmacy before discharge so the cost question is settled in advance.
• Through community programs: County public health departments and community organizations in California often distribute naloxone at no cost. The SAMHSA National Helpline can point you to local resources.

Where to Keep It and What to Check

Naloxone nasal spray should be stored at room temperature, out of direct sunlight, and in its original packaging. Hot cars are a common problem in California summers, so a car should not be the only place a household keeps it. Every package carries an expiration date. Write that date somewhere you will see it, such as a phone calendar reminder a month before it expires.

Pick one fixed, visible spot in the home, such as the kitchen or the main bathroom, and keep it there. A second set can go in the bag of the person in recovery. The rule is that everyone in the house can name the location without thinking.

The Two-Dose Instruction, Step by Step

Follow the directions printed on the package you have, because they are the authoritative version for that product. For the common 4 mg nasal spray, the steps generally look like this:

1. Try to wake the person. Shout their name and rub firmly on the center of their chest. Signs of an opioid overdose can include slow or stopped breathing, blue or gray lips or fingertips, pinpoint pupils, and being unresponsive.
2. Call 911. Say the person is not breathing or will not wake up.
3. Lay the person on their back, insert the nozzle into one nostril, and press the plunger fully.
4. If they do not respond within 2 to 3 minutes, give a second dose in the other nostril with a new device.
5. If they are breathing, roll them onto their side. Stay with them until emergency responders arrive, even if they wake up.

Naloxone works only on opioids. It will not reverse an overdose caused by alcohol, benzodiazepines, or stimulants alone. But because fentanyl contamination is so common, and because naloxone is not expected to harm someone who has no opioids in their system, responders are generally advised to give it whenever an opioid overdose is possible. California also has a Good Samaritan law that offers some legal protections to people who call for help during an overdose. The protections have limits, but the guidance from public health agencies is consistent: call.

A Related Safety Note on Alcohol and Benzodiazepines

Some people leave residential treatment while still tapering a benzodiazepine, or with a history of heavy alcohol use. Withdrawal from alcohol and from benzodiazepines can cause seizures and can be life-threatening. Never stop either one abruptly after discharge without guidance, and never try to manage that withdrawal at home on your own. If the medication plan changes or a return to drinking happens, the next step is medical supervision, not a home taper.

The Household Check to Run Your First Night Home

This takes about ten minutes, and it is the single most useful thing a family can do on day one:

1. Count the doses. Confirm there are at least two, and read the expiration date out loud.
2. Agree on the spot. Put the naloxone in its fixed location while everyone is watching.
3. Hand it around. Each adult in the house should hold the device and read the package directions once. Practice the motion without pressing the plunger.
4. Say the sequence. Out loud: “Shout and rub, call 911, spray, wait 2 to 3 minutes, second spray, side position, stay.”
5. Set the reminder. Put the expiration date in a phone calendar for every adult in the home.

The point is not to dwell on the worst case. It is to make the response automatic.

Questions to Ask Before Discharge

If you or a family member is in residential treatment now, bring these questions to the next discharge-planning meeting: Will the program provide naloxone or send a prescription to my pharmacy? Can a family member attend a short training before I leave? Does my aftercare plan include a clinician I can call if I return to use? Our treatment consultants can help families think through these questions. Call (877) 328-1968 to talk with someone today.
