Quick answer
Heroin addiction is treated most effectively with FDA-approved medications such as methadone or buprenorphine, combined with counseling and support. Treatment often begins with medically supervised detox and continues in inpatient, intensive outpatient or outpatient care. Because heroin is often mixed with fentanyl, overdose risk is high, so carrying naloxone is strongly recommended.
What are the signs of heroin addiction?
Heroin is an illegal opioid made from morphine. It can be injected, snorted or smoked. Doctors diagnose heroin addiction as opioid use disorder (OUD), a chronic but treatable brain condition.
Clinicians use 11 DSM-5 criteria. In everyday language, they ask whether in the past year you have:
- Used heroin in larger amounts or for longer than you meant to
- Tried to cut back or quit and couldn’t
- Spent much of your time getting, using or recovering from heroin
- Felt strong cravings
- Fallen behind at work, school or home
- Kept using even when it hurt your relationships
- Dropped activities you used to enjoy
- Used in risky situations, such as alone or while driving
- Kept using despite health problems
- Needed more to feel the same effect
- Had withdrawal when you stopped
Two to three signs suggest mild OUD, four to five moderate, and six or more severe.
Family and friends might notice small pupils, drowsiness or nodding off, long sleeves in warm weather, needle marks, burnt spoons or foil, missing money, or withdrawal from relationships.

What does heroin withdrawal look like?
When someone dependent on heroin stops, withdrawal symptoms can feel like a severe flu with intense restlessness. Common symptoms include:
- Muscle and bone pain
- Sweating, chills and goosebumps
- Runny nose, watery eyes and yawning
- Nausea, vomiting and diarrhea
- Anxiety, irritability and insomnia
- Strong cravings
Heroin withdrawal timeline
| Time since last use | What to expect |
|---|---|
| 8–24 hours | Anxiety, cravings, sweating, yawning, runny nose |
| Days 1–3 | Symptoms peak: aches, vomiting, diarrhea, chills, insomnia |
| Days 4–10 | Physical symptoms gradually ease |
| Weeks to months | Cravings, fatigue, low mood and poor sleep may linger |
Heroin withdrawal is rarely deadly on its own, but dehydration can be serious, especially for people with other health conditions. The biggest risk is what happens next: after even a few days without heroin, tolerance drops. Returning to a previous dose, especially if it contains fentanyl, can cause a fatal overdose.
That’s why experts recommend medically supervised detox that leads directly into ongoing treatment, rather than detox by itself.
What treatments work for heroin addiction?
Medications for opioid use disorder
Using medication alongside counseling is often called medication-assisted treatment (MAT). According to NIDA, these medications are safe and effective and help people stay in treatment.
- Methadone is a long-acting opioid taken daily at a certified opioid treatment program. It prevents withdrawal and reduces cravings. Find out more about methadone clinics.
- Buprenorphine is a partial opioid agonist. It eases cravings and has a ceiling effect that lowers misuse risk. It comes as a daily film or tablet, or a monthly injection, and can be prescribed in a doctor’s office.
- Extended-release naltrexone is a monthly injection that blocks opioid effects. You must be off opioids for several days before starting it.
Medications for withdrawal symptoms, such as lofexidine, can make detox more comfortable but are not a substitute for long-term treatment. Read more on our medication-assisted treatment page.
Behavioral therapies
- Cognitive behavioral therapy (CBT) teaches you to recognize triggers and handle cravings.
- Contingency management gives rewards for goals like negative drug tests.
- Family therapy helps repair trust and build a supportive home.
- Peer support groups and recovery coaches offer encouragement from people with lived experience.
Many people who use heroin also have trauma, depression or anxiety. Dual diagnosis treatment treats these conditions together.
What level of care do you need?
Clinicians often use the ASAM Criteria, a set of guidelines from the American Society of Addiction Medicine, to recommend the right intensity of care.
| Level of care | What it offers | Consider it if… |
|---|---|---|
| Detox | Medical help through withdrawal; start MAT | You’re physically dependent |
| Inpatient/residential | 24/7 care in a structured setting | You’ve had overdoses, repeated relapse or an unsafe home |
| Partial hospitalization (PHP) | Treatment most of the day, home at night | You need daily structure with a stable home |
| Intensive outpatient (IOP) | 9 or more hours of therapy per week | You want to keep working or caring for family |
| Outpatient | Regular counseling and medication visits | You’re stable or stepping down from more care |
A partial hospitalization program (PHP) is the most intensive form of outpatient care. An intensive outpatient program (IOP) offers several sessions a week. After rehab, some people move into sober living for extra support.
How can you prevent a heroin overdose?
Heroin overdose slows or stops breathing. Signs include pinpoint pupils, blue lips or nails, gurgling or snoring sounds, a limp body and not responding.
If you think someone is overdosing:
- Call 911.
- Give naloxone (Narcan) right away. Give a second dose after 2 to 3 minutes if they don’t respond.
- Lay them on their side and stay with them.
Naloxone is safe and can’t harm someone who isn’t on opioids. The FDA approved Narcan nasal spray for over-the-counter sale in 2023. Because heroin often contains fentanyl, never use alone, and keep naloxone close. Learn more on our fentanyl addiction page.
How do you pay for heroin rehab?
Costs vary widely by setting, length of stay and insurance. Most health plans cover substance use treatment as an essential health benefit under the Affordable Care Act. Federal parity law requires that addiction coverage be no more restrictive than coverage for other medical care. Still, what you pay depends on medical necessity, prior authorization, network status, your deductible and your out-of-pocket maximum. Federal law requires state Medicaid programs to cover FDA-approved medications for OUD.
How do you get help for heroin addiction?
You don’t have to wait for things to get worse. Talk to a doctor or clinic about starting medication, carry naloxone, and look for a program that offers MAT. Our guide on how to choose a rehab can help you compare programs. If you or someone you love is in crisis or thinking about suicide, call or text 988.
People recover from heroin addiction every day. To find a program that offers medication and fits your insurance, call our admissions helpline at (877) 847-2855. It’s free and confidential.
Frequently asked questions
What is the best treatment for heroin addiction?
NIDA and SAMHSA identify medications for opioid use disorder, especially methadone and buprenorphine, as the most effective treatment. They reduce cravings, prevent withdrawal and lower the risk of overdose death. Counseling and support add to their benefits.
How long does heroin withdrawal last?
Withdrawal often starts within 8 to 24 hours of the last dose, peaks around days 1 to 3, and eases over about a week. Cravings, sleep problems and low mood can last much longer, which is why ongoing treatment matters.
Is heroin withdrawal deadly?
Heroin withdrawal is rarely life-threatening by itself, though severe vomiting and diarrhea can cause dehydration. The bigger risk is overdose after withdrawal, when tolerance is lower. Medical support and long-term medication reduce that risk.
Does heroin contain fentanyl?
It often can. The CDC warns that illegally made fentanyl is frequently mixed into heroin and other street drugs. This makes every use unpredictable and raises the risk of a fatal overdose.
Can I keep my job while getting treatment for heroin addiction?
Many people do. Outpatient care, intensive outpatient programs and office-based buprenorphine allow you to keep working. Federal laws such as the FMLA may also protect your job if you need time off for treatment.
Where can I get naloxone?
Naloxone nasal spray is sold over the counter at many pharmacies. Health departments and community programs often provide it for free. Keep it where friends and family can find it.
