If someone might be overdosing, call 911 now. Do not wait to see if it is withdrawal. Slow or missing breaths are an emergency. Being hard to wake is an emergency sign. It is hard to tell the difference without medical help.
This guide covers emergency steps. It shows how withdrawal and overdose differ. It explains professional support options. We run a U.S. treatment directory. We are not a treatment provider.
If Opioid Overdose Is Possible, Call 911 Now
Do not wait to figure out if the symptoms are withdrawal or an overdose. If you suspect an opioid overdose, call 911 immediately. Delaying help to check for specific signs can be dangerous.
- Call 911 right away. Tell the dispatcher you suspect an opioid overdose.
- Use naloxone if you have it. Follow the directions on the package or device.
- Stay with the person. Do not leave them alone while waiting for help.
- Follow dispatcher instructions. They will guide you on how to support breathing until responders arrive.
Even if naloxone seems to help and the person wakes up, you still need emergency medical care.[1] The effects of naloxone can wear off before the opioids do, causing breathing to slow down again.
Common signs of opioid overdose include very small pupils, falling asleep or loss of consciousness, and slow, shallow breathing.[2] You can learn more about recognizing opioid overdose signs and obtaining naloxone for emergencies in our other guides.
Opioid Withdrawal vs Overdose: Signs at a Glance
Slow or stopped breathing and being hard to wake are emergency signs. If you see them, call 911.
These signs can overlap, so it is not always possible to tell withdrawal from overdose just by looking. Opioid withdrawal causes painful body symptoms when the body adjusts to less or no opioid use.[3] Opioid overdose is a medical emergency where the body’s functions, especially breathing, become severely impaired.[4]
| Feature | Possible Opioid Overdose Signs | Possible Opioid Withdrawal Signs |
|---|---|---|
| Alertness | Hard to wake, confused, or unresponsive | Awake, anxious, or agitated |
| Breathing | Slow, shallow, or stopped[4] | Normal rate |
| Pupils | May be very small (pinpoint) | May be normal or wide |
Opioids can slow down the brain parts that control breathing. This makes stopped breathing a key danger of overdose.[4] Withdrawal occurs when a dependent person cuts back or stops using opioids.[3] Withdrawal feels bad but is usually not life-threatening.[5] Doctors check a person's history and signs of dependence to guide care.[3] Because the safety risks are so different, always choose emergency help when unsure.
When Symptoms Overlap or You Are Unsure
It is hard to tell what is happening just by looking. Different drugs and health issues can look alike. Even family members may not know the difference.
Opioid intoxication and withdrawal can happen at the same time. This is common when more than one drug is involved. Mixing opioids with other depressants, like benzodiazepines, raises the risk of slow breathing and serious harm.[6] Dependence on other sedatives can also change how symptoms look. It can affect how the body reacts to withdrawal meds.[7] If sedatives are part of the picture, our guide to alcohol withdrawal mortality risk covers the specific dangers of stopping cold turkey.
Do not try to fix this at home. If overdose is possible, call 911 now. Do not wait to see if they wake up. Do not guess based on one sign. Getting help quickly is the safest choice.
Opioid Withdrawal Symptoms and When to Get Care
Opioid withdrawal symptoms vary from person to person. Many factors influence how a person feels.[8] Not everyone has the same signs. Severity also differs. There is no single four-stage path for everyone. Our guide to the opioid withdrawal timeline explains how long symptoms typically last and what to expect during recovery.
Vomiting and diarrhea are common. These symptoms can cause dehydration. They may also upset body chemicals and minerals.[5] If these issues are bad or last a long time, get professional care. Do not try to manage complications alone at home.

Hydrocodone Withdrawal: A Cautious Timeline
Wondering when hydrocodone withdrawal starts? The older slide-deck source cited here gives estimates for short-acting opioids, but it does not establish a current, hydrocodone-specific timeline or separate estimates for immediate- and extended-release formulations.[3]
Immediate-release hydrocodone
A general estimate for short-acting opioids is not a prediction for an individual.[3]
Extended-release hydrocodone
The short-acting-opioid estimate does not establish a timeline for this formulation.
Possible longer-lasting symptoms
The cited source notes possible protracted withdrawal, so an estimate of the acute period is not a universal endpoint.[3]
Getting Professional Help for Opioid Withdrawal
Withdrawal feels bad, but it is rarely life-threatening. Still, you need safe help. Medical detox for opioid withdrawal offers a supervised place to get care. A clinician can check your health and manage your symptoms. This setting is not a full treatment plan. It prepares you for the next step. Our guide to opioid withdrawal management explains what to expect during the process and how to stay safe. Before you book a bed, our guide to opioid detox insurance coverage helps you verify what your plan actually pays for. To picture what that supervised setting looks like, our guide to the first day of opioid detox walks through intake and monitoring. If symptoms escalate, our guide to drug withdrawal emergency details when to seek immediate medical help.
For people with an active opioid use disorder, withdrawal management should be followed by treatment with OUD pharmacotherapy.[9] A clinician can discuss which care fits your needs. They can also explain FDA-approved medications for opioid use disorder. These include methadone, buprenorphine, and naltrexone.[10] You do not have to do this alone. If naltrexone is part of your plan, our guide to naltrexone and opioid use covers safety and withdrawal details. If cravings become hard to manage, our guide to cravings on mat offers safe steps and emergency signs to watch for.

You can explore medical detox programs for opioids to find local options that provide this kind of supervised support.
Overdose Risk After Reduced Use and Finding Ongoing Support
Your body changes when you use less or stop opioids, and your tolerance can drop after reduced use or a break.[11] If you use as much as before, you can more easily overdose because your body is no longer used to that level of exposure.[12]
For people with opioid dependence, treatment with methadone or buprenorphine is associated with lower all-cause and overdose mortality while they remain in treatment.[13]
Withdrawal care is just the start. Ongoing care can help reduce future risks. Read about opioid addiction treatment options to see what fits you.

Frequently Asked Questions
What is opioid withdrawal similar to?
Some symptoms can feel like the flu. This includes body aches, sweating, and stomach upset. That look-alike does not prove the cause is withdrawal. If symptoms worry you, get a professional check-up.
Are there four stages of opioid withdrawal?
There is no fixed four-stage plan for everyone. Doctors use a tool called the Clinical Opiate Withdrawal Scale. It is an 11-item tool to rate withdrawal symptoms.[15] A score helps guide care. It is not a diagnosis or a fix for emergencies.
Can opioid withdrawal be managed safely without medical help?
A health pro can help pick the safest setting for you. This guide does not give a home detox plan. If you are pregnant, get special clinical care. Do not try to handle withdrawal alone. Withdrawal has high relapse rates.[16]
Can naloxone cause withdrawal?
Yes, naloxone can trigger acute withdrawal symptoms. This happens in people who are dependent on opioids.[17] Do not hold back naloxone if you suspect an overdose. Call 911 and follow emergency steps right away.
Can overdose symptoms return after naloxone?
Yes, overdose signs can come back. Naloxone may wear off before some opioids do.[18] You still need emergency responders if the person improves. Stay with the person and follow 911 instructions.
Does naloxone reverse overdoses from other drugs?
Naloxone reverses opioid effects only. It does not reverse non-opioid drug effects.[19] If an opioid overdose is possible, call 911 immediately; do not delay the call to give naloxone. Use naloxone if you have it. Do not wait to figure out all the drugs used.
