Medical Detox in Los Angeles
Fentanyl now accounts for 91% of all opioid overdose deaths in Los Angeles County — up from just 19% in 2016. For most people with opioid or alcohol dependence, medically supervised detox is not optional — it is the critical first step that makes everything else possible.

What Is Medical Detox and Why Is It Necessary?
Medical detox is the first phase of addiction treatment — a 3–10 day process in which the body safely eliminates substances under continuous medical supervision. For opioid, alcohol, and benzodiazepine dependence, withdrawal can produce severe — and in some cases life-threatening — symptoms. Medical detox manages these symptoms with FDA-approved medications, prevents complications, and prepares the patient for the next level of care. Without medical supervision, opioid and alcohol withdrawal carry real risks of seizure, delirium tremens, and overdose on relapse.
What Happens During Medically Supervised Detox?
During detox, patients are monitored around the clock by physicians and nurses. Vital signs are checked regularly. Medications are administered to manage withdrawal symptoms — buprenorphine or methadone for opioid withdrawal; benzodiazepines and anti-seizure medications for alcohol; clonidine and comfort medications as needed. As stabilization occurs, a clinical assessment determines the appropriate next level of care — typically inpatient residential treatment.
How Long Does Detox Take?
Detox length depends on the substance, severity of dependence, and individual factors. Opioid detox: 5–10 days. Alcohol detox: 5–7 days (longer with severe dependence). Benzodiazepine detox: 7–14+ days due to risk of prolonged withdrawal. Stimulant detox (meth, cocaine): 3–7 days (less medical risk but psychological symptoms are significant). All timelines are extended when co-occurring conditions or poly-substance use are present.

What Drugs Require Medical Detox in Los Angeles?
The following substances require or strongly benefit from medical supervision during withdrawal: alcohol (seizure risk), benzodiazepines (seizure and delirium risk), opioids including fentanyl and heroin (severe physical withdrawal), prescription opioids (similar to heroin withdrawal), and in some cases methamphetamine (psychosis risk). Cannabis, cocaine, and stimulants do not typically produce physically dangerous withdrawal, but medical supervision is still recommended for poly-substance users.
Is Medical Detox Covered by Insurance in California?
Yes. Under California's SB 855 and the federal MHPAEA, state-regulated health plans must cover medical detox at the same level as any comparable medical procedure. Most PPO plans cover the full duration of medically necessary detox. Call (213) 516-2713 to verify your coverage before admission — it takes minutes and costs nothing.
What Comes After Detox?
Detox addresses only the physical component of addiction — it does not address the psychological or behavioral causes of substance use. Without continuing care, relapse rates after detox alone are very high. Most clinical guidelines recommend transitioning directly from detox to inpatient residential treatment, where intensive therapy, group work, and dual diagnosis care begin. A placement advisor will coordinate this transition.
Fentanyl Withdrawal: What to Expect
Fentanyl withdrawal begins within 8–24 hours of last use and peaks at 36–72 hours. Symptoms include intense cravings, muscle aches, sweating, nausea, vomiting, diarrhea, anxiety, and insomnia. Fentanyl's high potency means withdrawal can be especially intense — and the risk of fatal overdose on relapse is extremely high because tolerance resets rapidly during detox. Medical supervision with buprenorphine or methadone dramatically reduces symptom severity and prevents relapse during the withdrawal period.
Frequently Asked Questions
Detoxing at home from opioids, alcohol, or benzodiazepines is medically risky. Alcohol and benzo withdrawal can cause seizures and death without medical management. Opioid withdrawal, while rarely fatal in itself, is extremely uncomfortable — and the risk of fatal overdose if you relapse is highest in the first few weeks after stopping, when tolerance has dropped. Medical detox in a supervised setting is always the safer option.
Medication-Assisted Treatment (MAT) uses FDA-approved medications — buprenorphine (Suboxone), methadone, or naltrexone — to reduce cravings and prevent relapse. Most medically supervised detox programs use MAT for opioid withdrawal. Some continue MAT through residential treatment and beyond. Research consistently shows MAT reduces overdose mortality and improves long-term recovery outcomes.
