Key Takeaways
- Methadone withdrawal is a physical and psychological reaction to stopping methadone use after the body has become dependent on it, and it is generally more prolonged than withdrawal from short-acting opioids.
- Symptoms typically begin within 30 hours of the last dose, peak between days 5 and 7, and resolve for most people within about 10 days, though psychological symptoms can persist for a month or longer.
- Common symptoms include fever, chills, muscle aches, nausea, anxiety, depression, and intense cravings; severity depends on dosage, duration of use, and how methadone is stopped.
- Methadone dependency is often treated with medically supervised withdrawal and tapering protocols that focus on symptom management rather than the underlying dependence. Accelerated Neuro-Regulation (ANR) Treatment can address the underlying dependence in a single hospital stay without months of tapering or replacement medications — speak with our clinical team to learn more.
What Is Methadone?
Methadone is a long-acting synthetic opioid prescribed to treat opioid use disorder (OUD) and pain that cannot be managed with weaker medications. It is sold under its generic name and brand names like Methadose® and Dolophine®, and is available as an injectable liquid, powder, oral solution, and tablet.
When used in medication-assisted treatment (MAT) alongside counseling and behavioral therapy, methadone is meant to help people addicted to other opioids manage withdrawal symptoms. Taken as intended, it doesn't cause euphoria and can blunt the euphoric effects of other opioids, reducing the risk of relapse and overdose. For pain, it works by disrupting the transmission of pain signals between the body and the brain.
However, methadone is not a cure for opioid addiction. As a Schedule II controlled substance, it carries a high potential for abuse, and long-term use increases tolerance—meaning your body may require more of the drug for the same effect. Stopping or reducing use can trigger withdrawal, and it's common for people taking methadone, whether for pain or opioid cravings, to experience uncomfortable symptoms when trying to quit.
Methadone is also one of the three FDA-approved medications for medication-assisted treatment, but it can cause life-threatening overdose, especially when combined with benzodiazepines, antibiotics, or alcohol. Centers for Disease Control and Prevention data on provisional drug overdose death counts shows that around 3,000 people lose their lives to methadone each year.
While many people remain on methadone for years, full recovery from opioid addiction is possible. Understanding your treatment options is the first step toward achieving long-term recovery and regaining control of your life.
Methadone Withdrawal Symptoms and Timeline
Methadone withdrawal symptoms are the physical and psychological effects that develop when someone dependent on methadone reduces or stops use. The methadone withdrawal timeline typically begins within 30 hours of the last dose and peaks 5–7 days later. Acute physical symptoms usually subside past day 10, while psychological symptoms — including depression, cravings, and a strong urge to relapse — can persist for three weeks or longer. Severity and duration vary based on dosage, consumption method, and metabolic rate.
Severity also depends largely on how methadone is stopped. Tapering under medical supervision typically produces a milder withdrawal, while quitting "cold turkey" can lead to intense symptoms that may require medical attention. Severe symptoms also raise the risk of relapse, and relapsing after a period of abstinence sharply increases the risk of a potentially fatal opioid overdose. For this reason, no one should attempt to quit methadone abruptly or without medical supervision.
Common methadone withdrawal symptoms include:
The specific symptoms a person experiences — and their intensity — depend on which phase of withdrawal they are in.
First 30 Hours: First symptoms (often flu-like)
Since methadone is a long-acting opioid, most people experience the first methadone withdrawal symptoms within 30 hours of their last dose. In the beginning, methadone withdrawal can feel no different than the flu. Common symptoms during this phase include:
- Fever
- Chills
- Muscle aches
- Nausea and vomiting
- Rapid heartbeat
Days 2–10: Peak intensity (often days 5–7)
After the first couple of days, methadone withdrawal symptoms become increasingly intense and usually peak within 5–7 days of the last dose. Symptoms may take longer to peak in people with severe methadone addiction. Symptoms during this phase often include:
- Intense drug cravings
- Anxiety
- Depression
- Insomnia
- Restlessness
- Agitation
- Hallucinations and paranoia
Days 11–21: Acute physical symptoms subside
Acute physical symptoms typically begin to subside past day 10, though psychological symptoms often persist or intensify during this phase. Common symptoms during this phase include:
- Depression
- Persistent drug cravings
- Strong urge to relapse
- Decreased energy
- Loss of pleasure or motivation
Long-term symptoms
Some people continue to struggle with psychological withdrawal symptoms for up to a month or longer. When these symptoms persist, they may meet the criteria for post-acute withdrawal syndrome (PAWS). Long-term symptoms often include:
- Fatigue
- Depression
- Anxiety
- Sleeping problems
Methadone Post-Acute Withdrawal Syndrome (PAWS)
Methadone post-acute withdrawal syndrome (PAWS) is a prolonged form of withdrawal in which symptoms — primarily psychological — persist after the acute phase has resolved. According to SAMHSA, protracted withdrawal symptoms can last for weeks, months, or in some cases, years following cessation.
While most people overcome the symptoms of methadone withdrawal in just over a week, this isn't the case for those with PAWS. The effects of methadone PAWS are primarily psychological, with the most common symptoms being:
- Poor concentration
- Interrupted sleeping patterns
- Indifference
- Lethargy
- Loss of appetite
- Mood swings
- Worsening of mental illnesses like depression, anxiety, and bipolar disorder
When you're suffering from PAWS, it may feel as if your struggle with opioid addiction will never end. However, it is not necessarily a permanent condition. Receiving proper medical help is key to overcoming it and reducing the risk of relapse.
How to Detox From Methadone Safely
You should seek medical help to detox from methadone safely. Whether you're taking methadone for pain relief or as part of opioid addiction treatment, you should not stop taking it without consulting your doctor — doing so can lead to severe symptoms, increasing the risk of relapse, methadone overdose, and death.
Detoxing from methadone can be a lengthy and dangerous process. Some symptoms may be mild enough to be helped with home remedies such as over-the-counter medications, but others can put your life on the line — especially if you have underlying medical conditions. There have been cases of people dying during opioid withdrawal, including from complications such as heart failure caused by extreme dehydration. If you experience persistent nausea and vomiting after quitting methadone, seek medical attention immediately.
For patients seeking a faster path, rapid detox might seem like an attractive solution. This anesthesia-assisted method quickly clears methadone from your system using opioid-blocking drugs such as naloxone. Since advanced rapid detox is done under sedation, it can reduce the intensity of withdrawal symptoms—but it can cost upwards of $20,000, and many patients relapse because rapid detox addresses symptoms rather than the underlying dysregulation of the endorphin-opioid receptor system. Research underscores how high the relapse risk is when detox is not followed by sustained treatment: one study of patients completing inpatient opioid detox found that 59% relapsed within one week of discharge. Rapid detox can also trigger precipitated withdrawal when opioid-blocking drugs are administered before methadone has cleared the system.
In contrast, Accelerated Neuro-Regulation (ANR) is a safe and comprehensive opioid addiction treatment designed to restore balance in the endorphin-opioid receptor system and address the physiologic roots of dependence. In doing so, it eliminates withdrawal symptoms and negates the risk of relapse when compared with detox-only approaches.
ANR Treatment for Methadone Dependence
For many patients, the prospect of months of tapering — or the indefinite cycle of replacement medications — is what makes methadone dependence feel inescapable. Accelerated Neuro-Regulation (ANR) was developed to address that cycle directly.
Rather than substituting one opioid medication for another or attempting to flush methadone from the system without addressing why dependence developed, ANR works by restoring the natural balance of opioid receptors, which become dysregulated during prolonged methadone use. For most patients, this is what makes lasting recovery possible: the underlying physical dependence is addressed in a single hospital stay, without prolonged tapering or the relapse risk associated with detox-only approaches.
"We have identified the biological roots of opioid dependency. Modulation of the endorphin receptor system is the new standard of treatment."
— Dr. Andre Waismann, Developer of ANR
Methadone Rapid Detox vs. ANR Treatment
| Factor | ANR Treatment | Rapid Detox |
|---|---|---|
| Treats | The root of the dependency | The withdrawals |
| Risk of complications such as heart attack, aspiration, and recurring cravings | No | Yes |
| Risk of precipitated withdrawal | No | Yes |
| Typical length of stay | Approximately 36 hours | Several hours to overnight |
| Typical cost | $21,500 | $20,000 or more |
| Number of patients treated | Over 25,000 | Unknown |
| Performed in a hospital ICU setting | Yes | No |
| Performed only by a board-certified anesthesiologist and intensivist | Yes | No |
| Pre-procedure evaluation and stabilization by a physician | Yes | Sometimes |
| Patients are always monitored using advanced critical care equipment | Yes | No |
| Reversal and elimination of physiological cravings | Yes | No |
Clinical features of ANR for methadone dependence:
- Inpatient hospital setting. ANR is performed under sedation in the ICU of an accredited hospital, with patients monitored throughout treatment by board-certified anesthesiologists and critical care physicians.
- No replacement medications. Because ANR does not use partial agonists or antagonists, it does not extend dependence on a replacement drug or carry the risk of precipitated withdrawal.
- Safety. ANR Treatment is tailored to each patient's medical history, including those with complex underlying conditions, thereby negating the risk of side effects.
- Speed. ANR is designed as a short-duration treatment, with an average hospital stay of just 36 hours, helping patients recover from opioid addiction in a matter of days. As the only center focused exclusively on opioid addiction, ANR delivers a highly specialized approach to care.
For your convenience, you can find ANR centers around the world, including:
- Florida, USA
- Tbilisi, Georgia
- Goiânia, Brazil

Frequently Asked Questions
1. What does methadone withdrawal feel like?
Methadone withdrawal often feels like a severe, drawn-out flu in its early days, transitioning into intense psychological distress as it peaks. Patients commonly describe deep fatigue, body aches, sweating, and gastrointestinal symptoms in the first few days, followed by anxiety, depression, insomnia, and powerful cravings during the peak phase. Because methadone is long-acting, the experience tends to feel slower in onset but longer in overall duration than withdrawal from short-acting opioids like heroin or oxycodone.
2. Can you die from methadone withdrawal?
Methadone withdrawal is rarely fatal on its own, but it carries serious indirect risks. The most significant is relapse — patients in acute distress may use opioids to stop the symptoms, which sharply increases the risk of overdose. Severe dehydration from prolonged vomiting and diarrhea can also become medically dangerous if untreated, particularly in patients with underlying heart, kidney, or mental health conditions. Anyone experiencing chest pain, difficulty breathing, severe lightheadedness, or suicidal thoughts during withdrawal should seek emergency care immediately.
3. Is methadone withdrawal worse than heroin withdrawal?
Methadone withdrawal is generally not more intense than heroin withdrawal at peak, but it lasts substantially longer. Heroin withdrawal typically resolves within 5–7 days, while acute methadone withdrawal can last 10 days or longer, with psychological symptoms persisting for weeks. The trade-off makes methadone withdrawal feel more drawn-out and exhausting, even when individual symptoms are no more severe than those of shorter-acting opioids.
4. Why does methadone withdrawal last so long?
Methadone withdrawal lasts longer than withdrawal from most other opioids because methadone has a long elimination half-life that averages around 24 hours and can range from 8 to 59 hours, depending on the individual, far longer than drugs like heroin, oxycodone, or hydrocodone. The body releases methadone slowly, which delays both the onset and the resolution of withdrawal. This is also why the first symptoms typically don’t appear until around 30 hours after the last dose, rather than within hours.
5. Can you detox from methadone in a week?
Conventional methadone tapers and outpatient detox programs typically take weeks to months, and many patients struggle to complete them due to the long withdrawal timeline. Faster medical detox options exist, but most still require ongoing care to address the underlying physical dependence. However, Accelerated Neuro-Regulation (ANR) addresses methadone dependence in a single hospital stay of approximately 36 hours, followed by 3 days of post-discharge in-person follow-ups by ANR staff. The patient does not experience withdrawal in the process.
