Key Takeaways
- Medical detox, also called withdrawal management, provides structured monitoring and clinical support while a person stops alcohol or another substance.
- Alcohol and benzodiazepine withdrawal can become medically dangerous, particularly after heavy, prolonged or regular use.
- Opioid withdrawal is not usually fatal by itself, but vomiting, diarrhea, dehydration, co-occurring illness, strong cravings and reduced tolerance can create serious risks.
- Stimulant withdrawal can involve profound exhaustion, depression, anxiety, paranoia, sleep disruption or suicidal thinking even when physical symptoms are less dramatic.
- Detox is not automatically required for every person entering addiction treatment, and it is not complete treatment for a substance use disorder.
- The length of detox and any medication plan should be based on symptoms, substances, health history and response to treatment rather than one fixed timeline.
- How Sanctuary helps: Sanctuary provides individualized medical detox in Los Angeles and plans the transition into residential, outpatient, medication-supported or other continuing care.
Stopping alcohol or drugs can affect the body and brain in very different ways depending on the substance, amount, frequency, duration and the person’s health. Some withdrawal syndromes are primarily uncomfortable. Others can involve seizures, delirium, psychiatric crisis or another medical emergency. A person may also be withdrawing from more than one substance without fully knowing what was contained in the pills, powders or other products they used.
Sanctuary Treatment Center provides medically-assisted detox in Tarzana for adults whose assessment shows that withdrawal management is an appropriate starting point. The detox plan can address current symptoms, medical and psychiatric risks, prescribed medications, hydration, nutrition, sleep and the next stage of addiction treatment.
Detox should not be treated as a cleanse or a single event that removes addiction from the body. Its purpose is to help a person become sufficiently stable to continue treatment for the broader substance use disorder.
What is Medical Detox?
Medical detox is a structured period of withdrawal management. The treatment team evaluates symptoms and risks, monitors the person’s condition, uses medication when clinically appropriate and responds when a higher medical or psychiatric setting is needed.
The word “detox” is also used online to describe juices, supplements, saunas, rapid cleanses and attempts to stop suddenly at home. Those approaches are not the same as clinical withdrawal management. They cannot reliably predict or treat seizures, delirium, severe dehydration, respiratory problems, dangerous changes in blood pressure or heart rate, psychosis or suicide risk.
A medical detox program may focus on:
- Assessing current and recent substance use
- Identifying alcohol, benzodiazepine, opioid or polysubstance withdrawal
- Monitoring symptoms and vital signs
- Preventing or treating complications when possible
- Providing medication based on clinical need
- Supporting hydration, nutrition, rest and physical stability
- Evaluating mental health symptoms and immediate safety
- Discussing medications for opioid or alcohol use disorder
- Preparing the client for continued addiction treatment
Detox is one part of the addiction treatment continuum. Someone who does not have significant withdrawal risk may be appropriate to begin at another level of care.
Who May Need Medically Supervised Detox?
A professional assessment is especially important when a person:
- Drinks heavily or regularly and has experienced withdrawal before
- Has had an alcohol- or benzodiazepine-related seizure, hallucinations or delirium
- Regularly takes alprazolam, clonazepam, lorazepam, diazepam or another benzodiazepine
- Uses fentanyl, heroin, prescription opioids or counterfeit pills and fears withdrawal
- Combines alcohol, opioids, benzodiazepines, sleep medications, gabapentinoids or other depressants
- Uses cocaine, crack or methamphetamine and experiences severe depression, paranoia or suicidal thinking during a crash
- Uses kratom extracts, 7-OH or another opioid-like product regularly
- Has recently overdosed or required naloxone
- Has significant medical conditions or takes multiple prescriptions
- Has severe vomiting, diarrhea, poor nutrition or dehydration
- Has tried to stop before but returned to use because symptoms became overwhelming
- Does not have a safe, stable place to stop using
- Is uncertain what substances were actually consumed
The presence of one factor does not automatically determine the appropriate setting. Placement should be based on the full clinical assessment, including the person’s withdrawal risk, physical health, mental health, home environment and available support.
What Happens During Detox at Sanctuary?
Initial Assessment
The team reviews which substances have been used, how frequently, in what amounts and by which routes. The assessment may also cover:
- The timing of the last use
- Current withdrawal symptoms
- Previous detox experiences
- History of seizures, delirium or psychosis
- Overdose history
- Medical diagnoses
- Mental health symptoms
- Current prescriptions and supplements
- Pregnancy status when relevant
- Nutrition, hydration and sleep
- The safety of the home environment
- The client’s goals and treatment preferences
Symptoms can change after admission. Ongoing reassessment is particularly important when several substances were used or the contents of an illicit product were unknown.
Individualized Withdrawal Plan
The medical plan depends on the substance, severity, timing, health history and the person’s response to care. Medication may be used to prevent or reduce certain complications, relieve specific symptoms or begin longer-term treatment for opioid or alcohol use disorder.
No one medication protocol is appropriate for every client. The treatment team should explain recommendations, potential benefits, risks and alternatives based on the individual assessment.
Monitoring and Support
Depending on clinical need and Sanctuary’s current program capabilities, care may include:
- Monitoring withdrawal symptoms and vital signs
- Medication administration and response monitoring
- Hydration and nutrition support
- Sleep and comfort measures
- Assessment of pain and other physical concerns
- Suicide-risk and psychiatric evaluation
- Education about overdose and reduced tolerance
- Coordination with emergency or hospital services when needed
- Planning for medication, residential treatment or outpatient care after detox
The goal is not to promise symptom-free withdrawal. It is to recognize risks, address symptoms and support a safer transition into continued care.
Early Treatment Engagement
Someone experiencing acute withdrawal may not initially be ready for an intensive therapy schedule. Treatment can still begin through supportive contact, education, motivational work, medication discussions and planning for what comes next.
As the person becomes more stable, the treatment team can begin addressing cravings, triggers, mental health, relationships and the conditions surrounding continued substance use.
Detox by Substance at Sanctuary Treatment Center
Alcohol Withdrawal
Alcohol withdrawal can begin after a significant reduction in drinking, not only after alcohol is completely absent from the body. Symptoms may include tremors, sweating, anxiety, nausea, insomnia, headache, rapid heart rate and increased blood pressure.
Severe alcohol withdrawal can involve seizures, hallucinations or delirium tremens. A person with heavy or prolonged drinking, previous complicated withdrawal, serious medical illness or other sedative use should receive professional guidance before abruptly stopping.

Benzodiazepine Withdrawal
Benzodiazepines include medications such as Xanax, Klonopin, Ativan and Valium. Physical dependence can develop even when a person takes a benzodiazepine as prescribed. Dependence alone is not the same as addiction.
Abrupt discontinuation or an overly rapid reduction can cause serious withdrawal, including seizures or delirium in some cases. Current clinical guidance emphasizes individualized, gradual tapering under medical supervision rather than a universal rapid-detox schedule.
Someone entering treatment should disclose every prescribed and nonprescribed benzodiazepine they use. These medications should not be stopped suddenly without qualified medical guidance.
Opioid Withdrawal
Fentanyl, heroin and prescription opioids can produce physical dependence. Withdrawal may involve anxiety, restlessness, sweating, chills, muscle and joint pain, runny nose, yawning, insomnia, abdominal cramping, nausea, vomiting, diarrhea and strong cravings.
Opioid withdrawal is generally different from alcohol or benzodiazepine withdrawal, but it can still create serious risks. Dehydration, co-occurring illness, psychiatric distress and a rapid return to use are important concerns. Tolerance can decrease after a period without opioids, increasing overdose risk if use resumes.
Medication can be incorporated into opioid withdrawal and ongoing treatment. Buprenorphine timing should be individualized, particularly after fentanyl exposure. Ongoing outpatient methadone treatment for opioid use disorder is generally provided through a federally certified opioid treatment program and may require outside coordination. Naltrexone requires an adequate opioid-free period before initiation.

Stimulant Withdrawal
Cocaine, crack cocaine and methamphetamine withdrawal may involve a crash marked by exhaustion, increased sleep or insomnia, depression, anxiety, slowed thinking, irritability, loss of pleasure, increased appetite and intense cravings.
Some people experience paranoia, agitation, psychosis or suicidal thinking. These symptoms require prompt assessment even when the person does not have the same type of physical withdrawal seen with alcohol or benzodiazepines.
Treatment may focus on sleep, nutrition, psychiatric safety, cravings and engagement in behavioral care. There is currently no FDA-approved medication specifically for stimulant use disorder, although qualified clinicians may use medications for certain co-occurring conditions or selected off-label strategies.
Marijuana Withdrawal
Frequent or high-THC cannabis use can lead to physical dependence. Withdrawal may involve irritability, anxiety, insomnia, vivid dreams, decreased appetite, depressed mood, restlessness, headaches or gastrointestinal discomfort.
Not everyone with cannabis use disorder needs medical detox. Structured stabilization may be appropriate when symptoms are severe, mental health is worsening, other substances are involved or the person repeatedly returns to use because withdrawal feels unmanageable.
Kratom, 7-OH and Other Opioid-Like Products
Kratom leaf, concentrated extracts, 7-hydroxymitragynine products and other modified compounds can produce opioid-like effects, tolerance, dependence and withdrawal. Product strength and labeling may be unreliable, making it difficult to estimate exposure from the package alone.
Withdrawal may involve anxiety, insomnia, sweating, gastrointestinal distress, body aches, restlessness and cravings. The treatment plan should be based on the actual pattern of use, symptoms and other substances rather than assuming all products marketed as kratom are equivalent.
Withdrawal From Multiple Substances
Some people enter detox after using several substances together. For example, a person may combine opioids with benzodiazepines, alcohol with sleeping medications or stimulants with opioids. Counterfeit pills may also expose someone to substances they did not intend to use.
Polysubstance withdrawal requires careful assessment because symptoms and risks can overlap. A treatment plan that is appropriate for one substance may not adequately address another, and the person should disclose all known medications, supplements and substances to the admissions and clinical teams.
Drug Withdrawal Symptoms
Withdrawal symptoms occur soon after a person stops using or drinking. The timeline and intensity of these symptoms can vary. For instance, the types of substances a person uses, the length of their addiction, and their overall state of health can impact withdrawal.
Most people will have withdrawal symptoms within about twelve hours after they stop using. At first, withdrawal symptoms can appear mild. However, as time goes on, these symptoms can get more severe. Those with alcohol or opioid use disorders could have life-threatening withdrawal symptoms.
Common withdrawal symptoms include the following:
- Nausea, vomiting, and diarrhea
- Headaches and body pains
- Fever and chills
- Fatigue
- Anxiety and depression
- Sleep problems
- Drug and/or alcohol cravings
- Changes in appetite
- Irritability
- Profuse sweating
- Trouble thinking clearly
- Unpleasant dreams
- Shaking
Severe withdrawal symptoms are called delirium tremens. These symptoms can occur during detox from a severe addiction to alcohol and include:
- Hallucinations
- Delusions
- Mental confusion
- Seizures
- Tremors
Professionals at our detox facility in Los Angeles, CA will monitor a person’s symptoms. This will ensure a person doesn’t have dangerous medical concerns from withdrawal symptoms. In addition, each client will have support for mental health symptoms.
How Long Does Medical Detox Take?
There is no fixed detox duration that applies to every client. Length can be affected by:
- The substance or combination of substances
- Dose, frequency and duration of use
- Timing of the last use
- Previous withdrawal complications
- Current symptoms and response to medication
- Physical and mental health
- Prescribed medications
- The need for a gradual taper
- Insurance authorization
- The plan for the next level of care
Alcohol, opioid and stimulant withdrawal follow different patterns. Benzodiazepine tapering may extend well beyond a brief residential detox stay, and fentanyl exposure can complicate the timing of certain medications.
A treatment center should not promise that every person will be fully detoxed within a predetermined number of days. Discharge should be based on the person’s stability, ongoing risks and continuing-care needs rather than an advertised timeline.
Does Detox Remove Drugs From the Body?
The body naturally metabolizes and eliminates substances over time. Medical detox does not mechanically cleanse drugs or alcohol from the body, and the presence or absence of a substance in a test does not determine whether withdrawal or addiction has been resolved.
Clinical detox focuses on what happens while the body and brain adjust to reduced substance exposure. That includes monitoring symptoms, addressing complications, supporting stability and preparing the client for continued treatment.
Products marketed as detox drinks, supplements or cleansing kits do not treat substance use disorder. They also cannot reliably prevent dangerous alcohol or benzodiazepine withdrawal.
Medications Used During Detox
The medications used during detox depend on the substance, symptoms and person’s health. They may be intended to reduce withdrawal severity, prevent complications, manage a specific symptom or begin ongoing treatment for a substance use disorder.
Examples may include:
- Medications used to manage alcohol withdrawal symptoms
- A structured benzodiazepine taper when clinically appropriate
- Buprenorphine for opioid withdrawal and opioid use disorder
- Symptom-management medications for nausea, diarrhea, sleep or anxiety
- Medication for an independently diagnosed mental health condition
- Medications for alcohol use disorder when medically appropriate
- Continued treatment for an existing medical condition
Medication decisions must be individualized. A medication that is appropriate for one client may be unsafe or unnecessary for another because of medical history, other prescriptions, pregnancy, recent substance use or potential interactions.
Mental Health During Detox
Withdrawal can affect mood, sleep, thinking and perception. Someone who appears anxious, depressed or confused may be experiencing withdrawal, an independent mental health condition, the effects of recent intoxication or a combination of factors.
Symptoms that may require additional evaluation include:
- Severe depression
- Suicidal thoughts
- Panic
- Extreme agitation
- Paranoia
- Hallucinations
- Disorganized thinking
- Mania-like symptoms
- Inability to sleep
- Confusion
- Trauma-related distress
Some symptoms improve as withdrawal resolves and sleep returns. Others persist and require continued psychiatric or psychological care.
Sanctuary can incorporate dual diagnosis treatment when substance use occurs alongside appropriate co-occurring mental health concerns. Severe psychosis, immediate suicide risk or another acute psychiatric crisis may require hospital care before the person can participate safely in Sanctuary’s program.
Overdose Risk After Detox
Tolerance can decrease after a person stops using opioids. If they later return to the amount they previously used, the body may no longer tolerate that dose, increasing the risk of fatal respiratory depression.
The illicit drug supply may also contain fentanyl, nitazenes, xylazine or other unexpected substances. Someone intending to use cocaine or a counterfeit prescription pill may unknowingly be exposed to an opioid.
Overdose-prevention planning after detox may include:
- Providing or obtaining naloxone
- Teaching the client and family how to recognize an opioid overdose
- Discussing reduced tolerance
- Continuing medication for opioid use disorder when appropriate
- Developing a response plan for cravings
- Avoiding abrupt gaps in treatment
- Connecting the client with residential or outpatient care
- Identifying safe people to contact during a crisis
Call 911 after administering naloxone during a suspected overdose. Naloxone may wear off before the opioid does, and additional medical care may still be necessary.
What Happens After Detox?
Detox addresses acute withdrawal and stabilization. It does not by itself resolve cravings, trauma, depression, relationship problems, daily routines, access to substances or the environment the person will return to.
After detox, treatment may continue through:
- Residential addiction treatment
- Partial hospitalization
- Intensive outpatient treatment
- Standard outpatient treatment
- Medication for opioid or alcohol use disorder
- Individual, group or family therapy
- Dual diagnosis care
- Psychiatry and primary care
- Recovery support and peer services
- Treatment planning and aftercare
The transition should be planned before discharge whenever possible. An abrupt end to support immediately after withdrawal can leave the person vulnerable to cravings, reduced tolerance, overdose or a rapid return to the same environment.
Not every client needs every stage, and the sequence can change according to clinical needs, progress, home stability and available support.
Does Insurance Cover Medical Detox?
Many health plans include benefits for substance use disorder treatment, but coverage depends on the specific policy and the level of care the insurer considers medically necessary.
Coverage may be affected by:
- Network status
- Prior authorization
- Medical-necessity criteria
- Deductible and coinsurance
- Plan exclusions
- Length-of-stay reviews
- The facility and clinicians billing for services
Sanctuary can verify benefits and explain the information provided by the insurance carrier. Verification does not guarantee authorization, a particular length of stay or payment of every claim.
Why Choose Sanctuary for Medical Detox in Los Angeles?
Sanctuary Treatment Center provides medical detox in Tarzana for adults throughout Los Angeles and Southern California. The detox process is connected with a broader continuum of care rather than treated as an isolated service.

Frequently Asked Questions About Medical Detox
Is detox always the first step in addiction treatment?
No. Detox is appropriate when withdrawal management or medical stabilization is needed. A person who is medically stable may be able to begin in residential treatment, PHP, IOP or standard outpatient care.
Is it safe to detox at home?
That depends on the substance, degree of dependence, health history and current symptoms. Alcohol and benzodiazepine withdrawal can become life-threatening. Opioid or stimulant withdrawal can involve dehydration, psychiatric crisis or a rapid return to use. A qualified professional should assess risk before a person attempts to stop abruptly.
Will medication be used during detox?
Medication may be used when clinically appropriate. The exact plan depends on the substances involved, symptoms, health history, current prescriptions and response to treatment.
Can buprenorphine be started during opioid detox?
It may be started as part of opioid use disorder treatment when appropriate. The timing and induction strategy should be individualized, particularly after fentanyl exposure, to reduce the risk of precipitated withdrawal.
Does detox cure addiction?
No. Detox addresses acute withdrawal and stabilization. Continued treatment addresses cravings, behaviors, mental health, relationships and the recovery environment.
What if more than one substance is involved?
Tell admissions and the clinical team about every known substance, medication and supplement. Polysubstance use can change withdrawal risk and the appropriate treatment setting.
Can prescribed medications be continued?
Possibly. Bring a complete, current medication list and follow Sanctuary’s instructions for transporting prescriptions. Do not stop prescribed benzodiazepines, seizure medications, psychiatric medications or other drugs abruptly without medical guidance.
What happens if symptoms become too severe for Sanctuary?
The person may need transfer to an emergency department, hospital or another higher-acuity setting. Admissions can explain Sanctuary’s current emergency-transfer process.
Does insurance cover detox?
It may. Coverage depends on the plan, network, authorization and medical-necessity decision. Verification is not a guarantee of payment.
What is the difference between detox and residential treatment?
Detox focuses on acute withdrawal and medical stabilization. Residential treatment provides live-in addiction therapy, structure and recovery planning after the person is sufficiently stable to participate.
