Heroin Rehab in Los Angeles

Heroin addiction is a medical emergency in Los Angeles County, made vastly more dangerous by the presence of fentanyl in nearly every batch of street heroin. At Annandale Behavioral Health, we provide complete heroin rehab for Los Angeles residents — including medically supervised detox, Suboxone or Vivitrol-based MAT, residential treatment, dual-diagnosis psychiatric care, and structured aftercare. Our private 6-bed estate in Pasadena offers clinical excellence in a discreet, residential environment.

The fentanyl-heroin crisis in Los Angeles

The “heroin” sold on the LA-area street market in 2026 is rarely pure heroin. Most batches contain fentanyl — sometimes deliberately added to increase potency, often present as a contaminant. This makes every use a potential overdose event. LA County recorded over 2,000 opioid overdose deaths in the most recent reporting year, with fentanyl involved in the overwhelming majority.

For LA residents with heroin dependence, the calculus has fundamentally changed. Continued use carries an unprecedented risk of fatal overdose. Effective heroin rehab is no longer optional — it is potentially lifesaving.

Annandale’s heroin rehab program

Phase 1: Medical detox (5-10 days)

Heroin withdrawal is rarely life-threatening but is intensely uncomfortable. Symptoms peak around 72 hours after the last dose and include severe muscle aches, nausea, vomiting, diarrhea, restless legs, anxiety, insomnia, and overwhelming cravings. Our medical detox provides:

  • 24/7 nursing and physician oversight
  • Comfort medications to manage symptoms (anti-nausea, anti-diarrhea, muscle relaxants, sleep aids, clonidine for autonomic symptoms)
  • Buprenorphine initiation when appropriate (often via micro-induction if the patient has been using fentanyl-contaminated heroin)
  • Cardiovascular and vital-sign monitoring
  • IV fluids and nutritional support

Phase 2: Residential MAT initiation

Medication-assisted treatment dramatically improves heroin recovery outcomes. We offer three FDA-approved options:

  • Suboxone (buprenorphine/naloxone) — first-line choice for most patients. Learn more about Suboxone treatment.
  • Vivitrol (extended-release naltrexone) — monthly injection, requires full detox before initiation, blocks opioid effects
  • Methadone — appropriate for select patients, requires referral to a federally-regulated outpatient clinic post-discharge

Phase 3: Residential treatment (30-90 days)

Heroin recovery requires more than detox. Our residential program includes individual therapy three times per week, daily group therapy, trauma-informed care including EMDR where indicated, family therapy, psychiatric medication management for co-occurring conditions, and experiential therapy (equine, art, movement). Most patients stay 30-60 days in residential, with extended care available for severe addiction or complex co-occurring conditions.

Phase 4: Outpatient continuation and overdose prevention

Every Annandale patient discharges with: a written aftercare plan, an outpatient therapist match in LA, ongoing MAT prescription continuity, naloxone prescription (mandatory for all opioid-treated patients), connection to LA-area recovery communities, and 12-month alumni support included in tuition.

Who we treat

Annandale’s heroin rehab program serves adults (18+) with opioid use disorder including: street heroin dependence, prescription opioid addiction that progressed to heroin, polysubstance use involving heroin + methamphetamine or heroin + benzodiazepines, and patients with extensive treatment history including prior MAT failures. Our dual-diagnosis approach treats co-occurring depression, anxiety, PTSD, bipolar disorder, ADHD, and personality disorders alongside the addiction.

Frequently asked questions

How long does heroin rehab take?

Most patients need 30-60 days of residential care followed by 6-12 months of outpatient treatment and ongoing MAT. Research consistently shows that longer treatment durations correlate with better long-term outcomes, particularly for opioid use disorder.

Will I have to stay on Suboxone forever?

No — but you may want to. Some patients successfully taper after 12-24 months; others find long-term MAT provides the stability they need. Decisions about MAT duration are made collaboratively between you and your medical team.

Can I get heroin rehab in Los Angeles same-day?

Often, yes. Call (855) 778-8668 to begin the clinical assessment. For PPO-insured patients, we typically complete benefits verification and admission within hours.

Is heroin rehab confidential?

Yes. Annandale’s 6-bed estate model is designed for high-confidentiality clients. We do not share client information without explicit written consent.
