Heroin detox is the medical process of safely managing opioid withdrawal — intensely uncomfortable but, unlike alcohol or benzodiazepine withdrawal, rarely life-threatening on its own. The danger of unsupervised heroin detox lies elsewhere: the symptoms drive most people back to using, and the loss of tolerance during a few days of abstinence makes the return-to-use overdose risk extraordinarily high. Medical detox is about making the withdrawal survivable while clinically setting up what comes next.
At SILC Health, heroin detox typically begins with induction onto buprenorphine (or, when appropriate, methadone) — FDA-approved medications that stabilize the opioid receptors, eliminate most withdrawal symptoms, and dramatically reduce craving. From day one, the conversation includes medication-assisted treatment (MAT) for the longer term, because MAT roughly triples retention in recovery and significantly reduces overdose death risk.
Why medical detox
Why not just at home.
Heroin withdrawal itself is rarely fatal in otherwise healthy adults — but the intensity of symptoms (severe muscle aches, vomiting, diarrhea, restless legs, sleeplessness, and cravings) drives most people back to using within hours of trying to quit cold turkey. The return-to-use overdose risk is the silent killer of heroin withdrawal: a body that has lost tolerance over even 3–5 days of abstinence can die from the same dose that was routine the week before.
Medical detox addresses both halves. Buprenorphine or methadone induction makes withdrawal manageable — most people are functional within 24–48 hours of starting medication. The clinical setting prevents the impulsive return-to-use that kills people. And the immediate connection to ongoing care means there is no "clean detox, then nothing" gap where 80%+ of people relapse.
Timeline
What withdrawal looks like.
6–12 hours after last use
Early withdrawal
- Anxiety, restlessness
- Muscle aches and joint pain
- Yawning, runny nose, watery eyes
- Sweating
- Cravings
1–3 days
Peak severity
- Severe muscle aches and bone pain
- Vomiting, diarrhea
- Goosebumps, dilated pupils
- Insomnia
- Restless legs
- Strong cravings
3–7 days
Resolution of acute symptoms
- Physical symptoms steadily improve
- Sleep begins to normalize
- Energy and appetite slowly return
- Mood remains low, motivation is fragile
Weeks 2–8
Post-acute withdrawal (PAWS)
- Sleep disturbances, fatigue, low mood
- Periodic cravings, especially with stress
- Strongly responds to continued MAT + therapy + structure
Medications
What we use, and why.
Buprenorphine + naloxone
Brand: Suboxone · Subutex · Zubsolv · Sublocade
First-line medication for opioid use disorder. Partial opioid agonist — eliminates withdrawal symptoms and most cravings while making it harder to overdose on other opioids. Induction begins once mild-to-moderate withdrawal has started. Often continued for months to years as part of ongoing MAT.
Methadone
Full opioid agonist used in detox and long-term MAT. Available only through licensed opioid treatment programs. Used when buprenorphine isn't a fit — including for people with very high tolerance or extensive prior buprenorphine failures.
Clonidine
Lowers blood pressure and reduces autonomic symptoms (sweating, anxiety, restless legs) during the acute withdrawal window. Adjunct to buprenorphine or used alone in some protocols.
Ondansetron, loperamide, NSAIDs
Brand: Zofran · Imodium
Symptomatic medications for nausea, diarrhea, and muscle pain during the acute window.
Naltrexone
Brand: Vivitrol
Long-acting opioid antagonist — blocks opioids entirely. Started 7–10 days after the last opioid use (so requires a fully clean detox first). One of the three FDA-approved MAT options. Vivitrol is the monthly injectable form.
Our Approach
How SILC handles heroin detox.
SILC Health's medical heroin detox begins with a full clinical assessment — recent use pattern, fentanyl exposure (now the dominant adulterant in street heroin), co-occurring medical issues, mental health, and recovery history. Most people induct onto buprenorphine within the first 24 hours once mild-to-moderate withdrawal has started. The shift from "in active withdrawal" to "stable on medication" usually happens within hours of the first dose.
Care goes well beyond the medication. Our team manages the symptomatic side — IV fluids for dehydration, anti-nausea care, sleep support, comfort measures. We watch for the medical issues that often co-exist with heroin use: untreated infections, dental problems, malnutrition, and infectious diseases that need follow-up. The medical detox window is often the first time in years someone has had a clinical conversation about their full health.
And the planning starts on day one. The single biggest predictor of long-term outcomes in opioid use disorder is whether someone stays on MAT. We work with you on a continued buprenorphine plan, a step-down to Vivitrol if that's your preference, or methadone maintenance if it's the right fit — and we make sure you leave detox with the prescription, the appointment, and a connection to the next level of care already in place.
After Detox
What comes next.
Most people stepping out of heroin detox continue MAT for at least 12 months — and the evidence is strong that longer durations meaningfully reduce relapse and overdose risk. Buprenorphine or methadone maintenance combined with residential, PHP, or IOP treatment is the standard of care. Vivitrol (long-acting naltrexone) is an option for people who prefer a non-agonist approach and can complete a fully clean detox window first.
Beyond medication, residential or PHP treatment addresses the patterns that built use — trauma, mental health conditions, environment, identity. Naloxone (Narcan) training and prescription is standard at discharge — if a return-to-use does happen, naloxone in the right hands prevents the death. Recovery community connection (mutual aid, recovery housing, peer support) is the structure that holds across the first year.
FAQ
Common questions.
How long does heroin detox take?
Acute heroin withdrawal typically lasts 5–10 days. Symptoms begin 6–12 hours after the last use, peak around days 2–3, and steadily improve through day 7. With buprenorphine or methadone induction, most acute symptoms are manageable within 24–48 hours. Post-acute symptoms (sleep, mood, periodic cravings) can persist for weeks, which is why ongoing MAT and treatment matter.
Is heroin withdrawal dangerous?
The withdrawal itself is rarely fatal in healthy adults — but the return-to-use overdose risk is extraordinarily high. After even a few days of abstinence, tolerance drops sharply, and a dose that was routine before can cause a fatal overdose. This is the silent killer of unsupervised heroin detox. Medical detox eliminates both the suffering and the risk.
What is the fastest way to detox from heroin?
The fastest medically appropriate approach is buprenorphine induction — most people are functional within 24–48 hours of the first dose. Rapid or ultra-rapid detox (anesthesia-based protocols) is widely discouraged: it carries serious medical risks, doesn't address craving or relapse prevention, and isn't supported by long-term outcome evidence. Buprenorphine + comprehensive aftercare is the gold standard.
Will I be put on Suboxone or methadone?
Most people induct onto buprenorphine (Suboxone) — it's the first-line option, has favorable safety, and can be continued long-term as part of MAT. Methadone is used when buprenorphine isn't a fit. Vivitrol (naltrexone) is an option for people who want a non-agonist approach and can complete a clean detox first. The choice is clinical and personal — our team walks through each with you.
Can I detox from heroin at home?
Most attempts to detox from heroin at home fail within 24–72 hours — not because people lack willpower, but because the withdrawal is intensely uncomfortable and use immediately resolves it. The bigger concern is the post-attempt overdose risk if tolerance drops and use resumes. Medical detox + ongoing MAT changes both halves of that equation.
Does fentanyl change how heroin detox works?
Significantly. Most street heroin in the U.S. now contains fentanyl, sometimes exclusively. Fentanyl's pharmacology (very potent, very short-acting) means withdrawal can hit harder and faster than classical heroin withdrawal, and the buprenorphine induction protocol may need to be adjusted to avoid precipitated withdrawal. Our clinical team handles this routinely. See our [fentanyl detox page](/detox/fentanyl) for the specifics.
What happens after heroin detox?
Most people continue MAT (buprenorphine, methadone, or Vivitrol) alongside residential, PHP, or IOP treatment. The single biggest predictor of long-term outcomes is staying on MAT — evidence strongly supports continuation for at least 12 months, often longer. Discharge includes a Narcan prescription, a continuing-care provider, and a treatment plan that doesn't depend on willpower alone.
