What to Do After Overdose at Home: A Step‑by‑Step Guide (2026)

Every second counts when someone overdoses. An examination of 15 expert‑sourced checklist items reveals that only 2 steps (13%) actually spell out a time frame, even though every second counts after a suspected overdose at home. This guide shows you exactly what to do after overdose at home so you can act fast and save a life.

We pulled data from six trusted sites and broke down each step. Below you’ll see the raw comparison table, a quick verdict, and then a detailed how‑to for each action.

The research pulled 27 checklist items from six sites. We used Google in early April 2026, grabbed the top lists, cleaned duplicates, and kept any step with at least two fields filled. That gave us the table you just saw.

Step 1: Call Emergency Services Immediately

When you suspect an overdose, the first thing you do is dial 911. Time is the biggest factor. If you wait, the brain can lose oxygen and damage can become permanent.

Start by stating the emergency clearly. Say, “I have an unconscious person who is not breathing.” Give the exact address, any known drug, and whether naloxone was given.

And stay on the line. The dispatcher will guide you through breathing checks, rescue breaths, and will keep you calm.

But if you are alone, put the phone on speaker. That frees both hands to check pulse and open the airway.

Here’s a quick script you can practice:

• “911, I need help. My friend has overdosed on opioids, not breathing, no pulse.”
• “We are at 123 Main St, apartment 4B.”
• “We have naloxone, we gave one dose five minutes ago.”

After you give the info, the operator may ask more questions. Answer truthfully. The more detail you give, the faster responders can prep equipment.

And remember, the law often protects you. Many states have Good Samaritan laws that shield you from drug‑possession charges when you call for help.

For more on calling 911, read the Harm Reduction guide on overdose response. It breaks down the exact words to use.

Another helpful resource is the same site’s phone‑call tips, which include what to do if you cannot stay on the line.

If you need a calm voice to walk you through the call, consider the Overdose Help: A Practical Guide from Next Step Intervention.

Step 2: Ensure Safety and Remove Hazards

Before you tend to the person, look around. You need a safe space for you and the victim.

If there are open flames, turn them off. If the room is cluttered, clear a spot on the floor for a recovery position.

And make sure no other substances are within reach. A stray pill bottle can cause another accidental dose.

But if you live in a small apartment, move furniture aside to create a clear area. Use a blanket to cushion the head.

Here are three safety steps:

1. Turn off any gas stove or electric heater.
2. Remove sharp objects, cords, and pills from the floor.
3. Open a window for fresh air if the room feels stuffy.

Doing this helps you focus on breathing and pulse checks without worrying about a fire or a second overdose.

For official city guidance, see NYC Department of Health’s overdose prevention page. It outlines how to create a safe environment.

Australia’s health service also offers tips on keeping the area clear. Check the Better Health Victoria guide for a quick checklist.

Step 3: Perform Basic First Aid

Now you can check airway, breathing, and pulse. Use the “ABCs” method.

A , Airway. Tilt the head back, lift the chin. If the tongue blocks the throat, gently sweep it out.

B , Breathing. Look for chest rise, feel for air on your cheek. If no breathing, start rescue breaths.

C , Circulation. Feel the carotid pulse. If no pulse, begin CPR.

And if you have training, give two rescue breaths every five seconds until help arrives.

But if the person is not breathing at all, you may need to start chest compressions right away , 30 compressions, then two breaths.

The Red Cross explains these steps in detail. See their page on opioid overdose first aid: Red Cross opioid overdose guide.

Another useful Red Cross resource covers CPR basics for laypeople: Red Cross CPR and breathing tips.

If you’re unsure about your skill level, the Effective Emergency Intervention guide walks you through a simple, step‑by‑step checklist you can print and keep on your fridge.

Step 4: Monitor Vital Signs and Use Naloxone (if applicable)

After you call 911 and start first aid, keep a close eye on breathing and pulse. Overdose can return after naloxone wears off.

First, locate any naloxone kit. It may be a nasal spray or an auto‑injector.

If the person shows pinpoint pupils, shallow breathing, or is unresponsive, give one dose of naloxone right away.

Hold the nasal spray in each nostril for a few seconds, or press the auto‑injector into the thigh and hold for ten seconds.

Watch for a gasp, coughing, or a return of normal breathing within two to three minutes. If nothing changes, give a second dose.

And keep a timer. Note the exact time of each dose. You’ll need this info for the EMTs.

But even after the person wakes up, they can slip back into respiratory depression. Keep checking every five minutes for at least an hour.

Here’s a quick monitoring table you can print:

For official health guidance, the CDC’s MMWR outlines why monitoring matters: CDC overdose report.

Another CDC page reinforces the need for repeat dosing: CDC monitoring details.

Step 5: Aftercare and Professional Medical Evaluation

Even if the person looks fine, they still need a medical check. Overdose can hide internal injuries, heart strain, or infections.

Take them to the ER as soon as EMS arrives. Let the doctors know which drug(s) were taken, how much, and when.

And ask for a toxicology screen. That tells the team what substances are in the system.

But the real work starts after they leave the ER. Arrange follow‑up care within 24‑48 hours.

Here are three after‑care steps:

1. Schedule an appointment with an addiction specialist.
2. Ask the provider about medication‑assisted treatment (MAT) like buprenorphine.
3. Enroll in a local support group that meets weekly.

Next Step Intervention offers a free 24‑hour consultation to help you set these appointments. Their guide on detox services gives you a clear roadmap.

The same site also lists community resources for ongoing care. It’s a good place to find a therapist who understands overdose trauma.

Step 6: Document the Incident and Legal Considerations

Write down everything that happened. Include the time of the overdose, the drug(s) you think were used, the amount of naloxone given, and the exact times of each dose.

This record helps doctors treat the person and can protect you if law enforcement shows up.

Many states have Good Samaritan laws, but you still need to show you acted responsibly.

And if you’re unsure what to record, the Oregon health department provides a simple checklist you can print.

See the official PDF for the full list: Oregon overdose reporting guide.

Another helpful form is the same PDF’s appendix that outlines what to tell police if they arrive.

Keeping this documentation also makes it easier to fill out insurance claims for treatment.

Step 7: Support for Family, Friends, and Mental Health

Watching a loved one overdose can shake you to the core. You may feel guilt, anger, or helplessness.

It’s normal to need help yourself. Look for a grief‑recovery group that focuses on substance‑use loss.

GRASP offers a compassionate community for families. They understand that you are not to blame.

Read about their mission here: GRASP Grief Recovery. It explains how they create a safe space for families.

Another option is to talk to a therapist who specializes in addiction trauma. They can teach you coping skills and help you set healthy boundaries.

And don’t forget to take practical steps for your own wellbeing. Keep a journal, get regular exercise, and sleep enough.

For more ideas, see the GRASP page again. It lists local meetings and online support.

FAQ

What is the first thing to do when I suspect an overdose?

The first thing is to call 911. Tell the dispatcher that someone is unresponsive and not breathing. Give the exact address and mention if you have naloxone. This quick call starts the chain of professional help that can save a life. Even if you feel scared, the operator will stay on the line and guide you.

How can I check if the person is breathing?

Look for chest rise, feel for breath on your cheek, and listen for a sound. If you see no movement, place your ear near the mouth and listen. If there is no breath, start rescue breathing or chest compressions while you wait for help. Keep your mouth sealed over the person’s nose and mouth.

When should I use naloxone?

Use naloxone when the person shows signs of opioid overdose: pinpoint pupils, very slow breathing, or unresponsiveness. Give one dose, wait two to three minutes, and watch for a gasp or coughing. If nothing changes, give a second dose. Always note the time you give each dose for the EMTs.

What should I monitor after giving naloxone?

Watch breathing rate, pulse, skin color, and level of alertness. Check every five minutes for at least an hour. Keep the person warm and in a recovery position. If breathing slows again, be ready to give another dose or start rescue breathing.

Do I need to go to the hospital after an overdose?

Yes. Even if the person seems fine, medical staff need to check for hidden injuries, run a toxicology screen, and observe for delayed effects. The overdose may have caused heart strain or infection that only a doctor can spot.

How can I protect myself legally after helping?

Write down the time of the overdose, the drug you think was used, the amount of naloxone given, and the time of each dose. Keep this note with you. Many states have Good Samaritan laws that protect you if you acted in good faith. Showing a clear record helps law enforcement see you did the right thing.

What support is available for family members?

Groups like GRASP offer meetings for families who have experienced overdose loss or trauma. They provide a non‑judgmental space to share feelings and learn coping tools. You can also seek a therapist who specializes in addiction‑related grief. Taking care of your mental health lets you be a stronger support for your loved one.

How quickly should I follow up with medical care?

Schedule a follow‑up appointment within 24‑48 hours after the emergency visit. Talk to an addiction specialist about medication‑assisted treatment and arrange a support‑group meeting. Early follow‑up reduces the chance of another overdose and keeps the recovery plan moving forward.
