How Long Does Medical Detox Take? Timeline by Substance

Many people are in medical detox for between three and 10 days. Your specific treatment timeline will depend on the substance(s) you use, how long and how heavily you used, and your overall health. Withdrawal from many opioids, stimulants, and mild to moderate alcohol use often improves within a week. Some situations, like benzodiazepine use, long-term alcohol use, or polysubstance use, may require a longer time in detox to manage and lessen severe symptoms.

Key takeaways

Medical detox typically takes about 3–10 days. Your exact timeline will be unique, and you can talk to an addiction treatment provider about what you can expect.
Withdrawal from substances, including alcohol and benzos, can be life-threatening. Never attempt to detox alone.
Detox can help you get stable, but it’s not the only treatment for addiction. Recovery can be stronger when attending residential or outpatient treatment after detox.

Is it safe to detox at home?

Detoxing alone is not always safe and can be life-threatening. Withdrawal symptoms caused by benzodiazepines (like Xanax or Valium), alcohol, or barbiturates can cause seizures, heart problems, or delirium tremens (DTs).^1,2 Trying to stop the use of multiple substances at once, or getting sober when you have another mental health or medical condition, can also make detox more complex and dangerous.

Trying to detox alone can cause severe and complex withdrawal symptoms, which is why it is generally considered unsafe. These symptoms may become medical emergencies. Call 911 or go to the closest emergency department if you or someone you love is withdrawing from substances and experiencing:

Seizures
Delirium tremens
Confusion
Hallucinations
Fever
Heart rate over 120
Chest pain
Vomiting blood
Inability to keep fluids down

Severe withdrawal symptoms can start quickly or unexpectedly, even if withdrawal seems manageable. The highest risk of delirium tremens, for example, is between 48 and 96 hours after last use. There is also a risk of hallucinations during alcohol detox and withdrawal that can make it more difficult to get help as your needs change.

While everyone has a different experience with detox, severe symptoms are more common during alcohol or benzo detox. Opioid withdrawal, while uncomfortable, is generally not life-threatening. However, if you use multiple substances, are pregnant, or have a medical/mental health condition, the risk of life-threatening symptoms is higher.

How long does detox take? Breakdown by substance

The table below shows common withdrawal timelines. Onset and peak refer to when symptoms may begin and feel most intense, not to a safe schedule for home detox. Long-acting substances, polysubstance use, medical complications, and clinician-directed tapers can extend any range.^3,4

Substance	Typical onset	Common peak	Typical acute detox	Clinical note
Alcohol	About 6–24 hours	About 36–72 hours	Often 2–10 days	Seizure and withdrawal-delirium risk can extend beyond early symptoms.
Short-acting opioids (including heroin)	About 8–24 hours	About 12–96 hours	Often 4–10 days	Opioid withdrawal is typically not life-threatening, but treatment can still help.
Long-acting opioids (including methadone)	About 12–48 hours	About 3–8 days	Often 10–20 days	Pregnant women should not undergo opioid withdrawal and should seek treatment.
Benzodiazepines	Often 1–4 days	Often during week one	Several weeks or longer	A clinician-directed taper is generally used instead of abrupt cessation.
Stimulants	Usually within 24 hours	Often days 2–4	Often about one week	Fatigue, low mood, sleep changes, and cravings may outlast the acute crash.

What is medical detox?

SAMHSA defines detoxification as “a set of interventions aimed at managing acute intoxication and withdrawal.”⁵ Medical detox is a supervised process that assesses risk, manages withdrawal symptoms, and stabilizes the body after you stop using alcohol or drugs.

Your care may include vital-sign monitoring, hydration and nutrition support, medications for symptom control, and a gradual substance taper when stopping too quickly would be dangerous. Detox is just one part of addiction treatment. It is helpful for helping you get stable after becoming sober, but you may need additional support for long-term recovery.

What happens during medical detox day by day?

During medical detox, you will receive treatment that meets you where you are in your sobriety journey. Your experience will be unique, and it depends on what symptoms you experience, your goals, your medical and mental health history, and any previous attempts at getting sober.

You may receive:

Intake and assessment (Day 1): The clinical staff will talk to you about your recent substance use, any medications you take, your health history (including if you’re pregnant), any previous attempts at getting sober, and your mental health. Their goal is to make sure your treatment plan matches your needs. Once your care plan is created, you’ll likely be shown to your room and start treatment.
Early withdrawal management and stabilization (Days 1–4): Depending on when you stopped drinking or using drugs, your symptoms may begin or peak soon after you enter treatment. Licensed addiction treatment providers will monitor your vital signs, offer support for hydration and nutrition, help create a calm place to rest, and—when appropriate—prescribe medications to manage symptoms.
Ongoing symptom management (Days 4+): The team will continue monitoring your symptoms as your body clears drugs and alcohol. They will likely use tools like the Clinical Institute Withdrawal Assessment for Alcohol, Revised (CIWA-Ar) or the Clinical Opiate Withdrawal Scale (COWS). These scales help measure your symptoms so they can monitor your progress.
Tapering plans and extended support: For people withdrawing from benzodiazepines or who otherwise have complex detox experiences, tapering may be a safer way to start recovery. Tapering involves providing gradually lower doses of a similar substance to avoid severe symptoms. Some tapering plans may last longer than a week. Your clinical team can help you understand what to expect if they recommend a taper.

Detox will likely be uncomfortable. Your care team will work to make your symptoms more manageable so you can transition into recovery. Sleep, eating, and staying hydrated may be the last things on your mind, but the professionals there to support you will help keep your space calm to let you rest, provide nutrition and hydration support, and establish routines that help you get stable.

Why detox timelines vary from person to person

Everyone will have a different experience in detox, including how long it takes to feel stable again. You may experience sooner, more intensely, and for longer than someone else. On the other hand, you may find that your symptoms become manageable more quickly.

Detox timelines vary for many reasons, including:

Type of substance used
Dose and duration of use
Whether multiple substances were used
Previous attempts at getting sober
Health conditions, including liver and kidney function
Whether post-acute withdrawal syndrome (PAWS) is present

Post-acute withdrawal syndrome is a set of symptoms that occur for weeks, months, or even years after stopping drugs or alcohol.⁶ PAWS symptoms are not typically life-threatening and are often less severe than acute withdrawal symptoms. Depression, anxiety, and brain fog are all common PAWS symptoms and can be risk factors for relapse.

Cost & insurance for medical detox

Many insurance plans cover detox when it is medically necessary. Some benefits may not cover all services provided in a detox program. Your financial responsibility will depend on your insurance coverage, which services are right for your care, and how long you may need to be in detox.

You can always verify your benefits before starting detox, so there are no surprises. The master’s-level admissions counselors at Santé Center for Healing are standing by to help. You can call 866.238.3154 or message us online to get help verifying your benefits. You can also verify your benefits for free online.

When clients visit and need support during withdrawal, our licensed professionals provide around-the-clock monitoring, support for nutrition, hydration, and sleep, and personalized treatment that may include medications.

Detox is often just the first step in addiction treatment. We also provide residential treatment, intensive outpatient, outpatient, and aftercare services that can help you continue recovery after detox on the right foot.

What happens after detox?

When you complete detox, you’ll be in a stable place to begin the next steps in your recovery journey. Treatment after detox may involve residential addiction treatment or outpatient care, depending on your needs. Your care may include FDA-approved medications to manage cravings, dual diagnosis support, family programming, and evidence-based therapy.

Continuing treatment after detox can help you maintain progress. Your risk of relapse after only detox is high because you may not have all the skills needed to stay sober. Relapsing after detox is dangerous, sometimes life-threatening, because tolerance drops sharply after getting sober.⁷

Frequently asked questions

Can you detox at home safely?

Do not assume home detox is safe. Alcohol, benzodiazepine, and barbiturate withdrawal can cause seizures or delirium, and a clinician should assess the risk before those substances are stopped. Call 911 for severe confusion, hallucinations, a seizure, chest pain, high fever, or other emergency signs.

How long does alcohol detox take?

Acute alcohol detox often lasts about 2 to 10 days, with symptoms beginning within hours and often peaking during the first 3 days. Withdrawal delirium may appear later, so improving early symptoms does not eliminate risk. The safest timeline comes from an individualized clinical assessment.

What is delirium tremens?

Delirium tremens, now often called alcohol withdrawal delirium, is a medical emergency involving severe confusion and autonomic instability; hallucinations and agitation may also occur.

Does insurance cover medical detox?

Many plans cover medically necessary substance use treatment, but the level of coverage varies. Ask admissions or your insurance carrier to confirm the network, deductible, coinsurance, authorization requirements, and estimated responsibility. Do not delay emergency care while waiting for a benefits check.

Is detox the same as addiction treatment?

No. Detox manages withdrawal and stabilizes the body so treatment can begin. Ongoing care may include medication, therapy, residential or outpatient services, family support, relapse prevention, and continuing support based on the client’s needs.

Is it safe to detox while pregnant?

Withdrawal during pregnancy requires prompt medical guidance because the safest approach depends on the substance, stage of pregnancy, and health of the pregnant person and fetus. Do not stop opioids, alcohol, or sedatives abruptly without professional advice. Read Can You Detox While Pregnant? for a focused overview, and seek urgent care for concerning symptoms.
