Is fentanyl detox different from heroin detox?

Yes, in meaningful ways. Fentanyl's potency drives higher tolerance and more intense physical dependence. The acute withdrawal peak is similar to heroin (24–72 hours after last use) but the post-acute withdrawal tail — sleep disturbance, mood instability, cravings — is typically longer and harder to manage without residential structure. SILC's fentanyl detox protocols account for this.

What is the standard MAT for fentanyl use disorder?

Buprenorphine (most often as Suboxone) is the most common MAT for fentanyl use disorder. Buprenorphine induction in fentanyl-tolerant clients requires careful clinical management to avoid precipitated withdrawal — the SILC medical team manages this in the residential phase. Extended-release naltrexone (Vivitrol) is an alternative for clients who prefer or require an antagonist-based approach.

What if I overdosed before coming to SILC?

Any history of overdose is critically important clinical information and is fully covered by the intake assessment. Prior overdose is itself an indication for residential care — the relapse-and-overdose loop is the primary driver of fentanyl mortality, and structured residential treatment substantially reduces that risk during the highest-risk early-recovery period.

How long is residential fentanyl rehab?

Length of stay is clinically determined. Most clients with fentanyl use disorder benefit from at least 60 days of residential treatment, often 90+ days, to manage the protracted post-acute withdrawal period and establish a stable MAT plan.

Are there fentanyl test strips available at SILC for after-care planning?

Fentanyl test strips and overdose-prevention education are part of standard discharge planning when relevant to the client's harm-reduction plan. SILC's clinical approach is recovery-oriented but harm-reduction-informed: reducing overdose risk is part of the treatment plan even in clients pursuing abstinence-based recovery.

Will my employer find out I went to fentanyl rehab?

Treatment records are protected by HIPAA and 42 CFR Part 2 (the federal regulation specifically protecting substance use disorder treatment records). SILC will not release information about your treatment without your written authorization. FMLA leave is typically taken without specifying the diagnosis.

What if I am also using cocaine, methamphetamine, or other substances?

Polysubstance use is common with fentanyl, particularly given fentanyl contamination of the stimulant supply. SILC programs treat polysubstance use disorder as a single clinical picture rather than sequentially. The intake assessment establishes the full substance use profile and the treatment plan addresses it as a whole.

What happens after fentanyl rehab ends?

Continuing care typically includes ongoing MAT under a community provider, individual therapy, recovery fellowship participation, naloxone access, and family support. SILC coordinates direct handoff with home-state providers for clients returning out of state.

Is fentanyl rehab covered by insurance?

Most major commercial insurance plans cover residential treatment for opioid use disorder, including fentanyl-specific care. SILC admissions verifies your specific benefits before any clinical commitment.

Treatment continuum

Fentanyl rehab.

Medical detox and full-continuum treatment for fentanyl use disorder. Fentanyl's potency and contamination of the broader opioid supply require specialized clinical protocols — longer withdrawal tail, overdose-prevention planning, and structured MAT integration.

Overview

Fentanyl rehab is the structured clinical treatment of fentanyl use disorder across the full continuum of care: medical detox managed with fentanyl-specific protocols, residential treatment for ongoing clinical work, partial hospitalization or intensive outpatient step-down, and long-term aftercare that typically includes medication-assisted treatment (MAT). Fentanyl is 50–100 times more potent than morphine and roughly 50 times more potent than heroin; it dominates the illicit opioid supply, contaminates most non-pharmaceutical pills sold as oxycodone or Xanax, and is the leading driver of U.S. overdose deaths. SILC Health operates licensed fentanyl rehab programs in California and Georgia, accepts most major insurance, and integrates buprenorphine or naltrexone-based MAT into long-term care plans. Fentanyl withdrawal has a longer post-acute tail than heroin or prescription opioids; the residential phase is when most of that protracted phase is best managed.

Section 1

What this is.

Fentanyl rehab is the full clinical continuum for fentanyl use disorder, treated as a severe opioid use disorder. It is distinct from generic opioid rehab in three ways: fentanyl's potency means tolerance, overdose risk, and the intensity of physical dependence are higher; fentanyl's pharmacokinetics produce a longer post-acute withdrawal tail; and fentanyl's contamination of the broader illicit drug supply means that clients may have been exposed without knowing it (pressed pills, contaminated cocaine or methamphetamine, contaminated heroin).

SILC's fentanyl rehab follows the American Society of Addiction Medicine framework. Acute withdrawal is medically managed with 24/7 nursing and physician oversight; medication-assisted treatment (typically buprenorphine or naltrexone) is initiated during the residential phase when clinically indicated; and overdose-prevention training (including take-home naloxone) is part of standard programming.

Long-term recovery from fentanyl use disorder is supported by sustained MAT, structured aftercare, and the same evidence-based behavioral modalities that treat any severe substance use disorder: CBT, DBT, family therapy, trauma-informed care, and recovery fellowship participation. The medication is necessary; it is rarely sufficient.

Section 2

The continuum of care.

1. Medical detox (5–10 days, ASAM Level 3.7)

Fentanyl detox at SILC is medically managed with 24/7 nursing and physician oversight. Withdrawal symptoms are managed pharmacologically; vitals and cognitive status are monitored continuously; complications are escalated immediately. Detox is the foundation — the work that follows is harder without it. See more →

2. Residential treatment (30 / 60 / 90+ days, ASAM Level 3.1–3.5)

Residential — sometimes called "inpatient" — is the longest and most intensive phase. Clients live on-site, participate in structured clinical programming daily, attend individual and group therapy, work with family when appropriate, build recovery skills, and stabilize physically and emotionally. Length of stay is clinically determined; most clients with moderate-to-severe substance use disorder benefit from at least 60 days.

3. Partial Hospitalization (PHP) — day treatment (ASAM Level 2.5)

PHP is the first step down from 24-hour residential care. Clients spend most of the day in clinical programming (typically 5–6 days per week, 5–6 hours per day) but return to sober living or stable housing each night. PHP supports reintegration into community life while still providing intensive clinical structure.

4. Intensive Outpatient (IOP) — 9–15 hours weekly (ASAM Level 2.1)

IOP runs 9–15 hours per week across 3 days, allowing return to work, school, or family responsibilities. Clinical focus shifts toward relapse prevention, ongoing therapy, and community reintegration. IOP often runs in parallel with recovery fellowship participation.

5. Outpatient + aftercare (indefinite)

Standard outpatient — individual therapy, psychiatric medication management when indicated, group therapy with a community provider — extends after IOP and continues indefinitely. Aftercare also includes recovery fellowship participation, sober living when appropriate, and ongoing alumni programming.

Section 3

Who this is for.

Fentanyl use disorder is treated as severe opioid use disorder. The DSM-5 framework applies; severity is graded by criteria met. Fentanyl's potency means most clients meet criteria for severe opioid use disorder within months of regular use.

Residential fentanyl rehab is clearly indicated for: any history of overdose, fentanyl exposure through pressed pills (counterfeit Oxy 30s, M30s, etc.), polysubstance use involving fentanyl-contaminated stimulants, daily fentanyl use that has not responded to outpatient intervention, co-occurring mental health conditions complicating recovery, or environments where naloxone access and supervised use cannot be assured.

A clinical assessment by a SILC admissions clinician determines the appropriate level of care. For fentanyl, the assessment weighs overdose history, current tolerance, MAT history, and the support system available for sustained recovery.

Section 4

A day in residential.

Residential fentanyl rehab is structured but not regimented. Most days at a SILC facility follow a clinical rhythm designed to balance therapeutic work, peer connection, physical wellness, and rest.

•Morning: Wake, vitals check during detox phase, mindfulness or meditation, breakfast, community meeting.
•Mid-morning to lunch: Individual therapy session or process group; psychiatric or medical check-ins when relevant.
•Afternoon: Skill-building group (CBT, DBT, relapse prevention), or experiential work (movement, art, equine therapy depending on facility), or family session when scheduled.
•Late afternoon: Physical wellness (exercise, beach walk at coastal California facilities, fitness room), peer time, dinner.
•Evening: Recovery fellowship meeting (AA, SMART, or alternative), reflection group, journaling, rest.

Family communication is supported per the client's preference. Family programming — visits, family therapy sessions, and structured education on supporting recovery — is clinically encouraged once initial stabilization is complete, typically after the first 5–10 days.

Buprenorphine + naltrexone

Both buprenorphine (Suboxone) and extended-release naltrexone (Vivitrol) are FDA-approved for opioid use disorder. SILC's medical team determines the appropriate MAT pathway for fentanyl use disorder during the residential phase.

Insurance + cost.

Most major commercial insurance plans cover residential treatment at SILC facilities, including Aetna, Anthem Blue Cross / BCBS plans, Blue Shield of California, Cigna, UnitedHealthcare, Surest, MultiPlan / PHCS, ConnectiCare, Oxford / Harvard Pilgrim, NYSHIP (Empire Plan), Empire BCBS, and Prairie States Enterprises. Network status with any given carrier varies by SILC facility and the patient's specific plan.

Out-of-state insurance is commonly accepted under most plans' out-of-state benefit provisions — Empire BCBS (NY), BCBS Texas, BCBS Florida, Aetna nationwide plans, and UnitedHealthcare nationwide plans typically cover treatment at SILC California facilities.

The SILC admissions team verifies your specific benefits, in plain language, before any clinical commitment. Most insured clients pay a manageable share after coverage; private-pay and financing options are available for clients without insurance or whose plans don't cover residential treatment at the clinically indicated level.

Section 6

Where SILC operates.

SILC Health operates licensed substance use treatment programs in two regions: coastal California (San Diego County) and North Georgia (Towns County). Medical detox is available at Cove Detox (Carlsbad), Leucadia Detox (Encinitas), Seaside Detox (Oceanside), Harbor Detox (Dana Point), and Riverfront Recovery Center (Hiawassee, GA). Residential addiction treatment is anchored by Southern California Recovery Centers (Carlsbad) and Riverfront Recovery Center (Hiawassee, GA).

Roughly two-thirds of SILC's California admissions originate from outside California — the climate, the recovery community, the distance from triggers at home, and the depth of California's continuing-care ecosystem are the most common reasons families choose to travel here for treatment. The Riverfront catchment skews more regional — drive-distance from Tennessee, Kentucky, Indiana, and surrounding states.
