Opioid Rehab: Medication-Assisted Treatment and Recovery

Key facts at a glance

Drug class	Mu-opioid receptor agonists
Includes	Oxycodone, hydrocodone, morphine, hydromorphone, codeine, tramadol, fentanyl, heroin
Clinical diagnosis	Opioid Use Disorder (OUD), mild / moderate / severe
Is withdrawal dangerous?	Rarely fatal on its own in a healthy adult, but severe. The real dangers are dehydration and post-withdrawal overdose from lost tolerance
FDA-approved medications	Buprenorphine, methadone, extended-release naltrexone
Overdose reversal	Naloxone nasal spray — available over the counter, often requires multiple doses
2025 US overdose deaths	69,973 estimated, down ~14% year over year (CDC NCHS provisional data)
Prescribing change	The DEA X-waiver requirement for buprenorphine was eliminated; any clinician with a standard DEA registration may now prescribe it

What is the difference between dependence and addiction?

This distinction is the most consequential one in opioid medicine, and conflating the two has caused real harm to pain patients.

Term	What it means
Tolerance	The same dose produces less effect over time. A normal pharmacological adaptation.
Physical dependence	The body has adapted and withdrawal occurs if the drug stops. Develops in essentially anyone taking daily opioids for a few weeks. Not a behavioral disorder.
Opioid use disorder	Compulsive use, craving, loss of control, and continued use despite accumulating harm. This is what “addiction” means clinically.

A cancer patient on scheduled morphine is dependent and not addicted. Someone buying pills from strangers, running out early every month and concealing it from two prescribers has opioid use disorder regardless of how the first prescription was written.

What are the warning signs of opioid use disorder?

• Prescriptions consistently running out days or weeks early
• Obtaining opioids from multiple prescribers, urgent care clinics, or online
• Taking more than prescribed, or changing the route — crushing, snorting, injecting
• Withdrawal symptoms between doses, or dosing specifically to prevent them
• Constricted pupils, nodding mid-conversation, slowed speech
• Persistent constipation, itching, weight loss, deteriorating dental health
• New and unexplained financial difficulty; missing money or valuables
• Continued use after an overdose, an arrest, or a serious medical warning

How do you recognize and reverse an opioid overdose?

Opioid overdose kills by suppressing the brainstem drive to breathe. It is usually not instantaneous — there is often a window of many minutes in which intervention succeeds.

Signs: unresponsive to shouting or a firm sternal rub; breathing very slow, shallow, gurgling or absent; pinpoint pupils; blue or grey lips, fingertips and face; limp body; snoring or choking sounds.

1. Call 911. California’s 911 Good Samaritan law protects people who summon help at an overdose from certain drug possession charges.
2. Administer naloxone — one spray into one nostril. Naloxone nasal spray is sold over the counter without a prescription and distributed free through California’s Naloxone Distribution Project.
3. Support breathing with rescue breaths if trained; begin chest compressions if there is no pulse.
4. Repeat naloxone every 2–3 minutes if there is no response. Fentanyl and nitazene overdoses frequently require several doses.
5. Stay with the person. Naloxone wears off in 30–90 minutes, which can be shorter than the drug it reversed. Overdose can recur.

If opioids are present in your household, keep naloxone there. Possessing it is not permission to use; it is the same logic as a fire extinguisher.

What is opioid withdrawal like, and how long does it last?

Short-acting opioids (heroin, oxycodone, hydrocodone): onset 6–12 hours after the last dose, peak at 24–72 hours, largely resolving over 5–10 days.
Long-acting opioids (methadone, extended-release formulations): onset 24–48 hours, with a flatter and longer course of two to three weeks or more.

Symptoms include deep muscle and bone aching, restless legs, yawning, rhinorrhea and watering eyes, alternating chills and sweating, dilated pupils, nausea, vomiting, abdominal cramping, diarrhea, insomnia, anxiety and severe craving.

The most dangerous period in opioid addiction is the week after withdrawal. Tolerance collapses quickly, so a dose that was routine before becomes potentially lethal. This is the central reason detox without follow-on medication and treatment produces poor outcomes and elevated mortality — and the reason Premier structures detox at Brier Lane as the entry point to a continuum rather than a standalone service.

Which medications treat opioid use disorder?

Medication	How it works	Practical considerations
Buprenorphine (Suboxone, Sublocade)	Partial agonist with a ceiling effect that makes respiratory depression far less likely	Prescribable by any clinician with a DEA registration; can be started in-office or by telehealth; monthly injectable form available
Methadone	Full agonist, long half-life, dispensed through licensed opioid treatment programs	Longest evidence base; often the better option at high tolerance or after buprenorphine has failed; take-home flexibilities are now permanent
Naltrexone XR (Vivitrol)	Monthly opioid receptor blocker; no opioid effect at all	Requires 7–10 days fully opioid-free before the first injection, which is the main obstacle. Well suited to patients completing residential care

There is no fixed correct duration. Many patients do best remaining on medication for years, some indefinitely. Discontinuation is a deliberate decision to make with a clinician during a period of stability, not a milestone to be rushed for the sake of appearances.

What else does effective treatment include?

Medication addresses the physiology; it does not by itself rebuild a life. Comprehensive treatment adds cognitive behavioral therapy and relapse prevention, contingency management, treatment of co-occurring depression, anxiety, PTSD or ADHD, non-opioid pain management, case management for housing and employment, family involvement, and peer support. Premier delivers these across the continuum, with VR-assisted therapy available for skills rehearsal in high-risk scenarios.

Which level of care is right for this?

Premier Health Group operates a full continuum across five Southern California facilities, so the answer is determined by a clinical assessment rather than by which program has a bed open.

If this describes your situation	Recommended level of care
Physically dependent, needs a comfortable and monitored withdrawal or a buprenorphine start	Medically supervised detox at Brier Lane
Severe OUD, injection use, prior overdose, or an actively using household	Residential treatment at Brier Lane or 5th Street
Stabilized on medication but needs daily clinical structure	PHP at Calle Azteca or Mountain View
Stable on medication, working or caring for family	IOP at Calle Azteca or Mountain View
Long-term medication management and relapse prevention	Outpatient at 4th Street

Frequently asked questions

Is buprenorphine just replacing one addiction with another?

No, and this misconception keeps people away from a treatment that prevents deaths. Addiction is defined by compulsion and harm. A patient stable on prescribed buprenorphine is physically dependent but not addicted: they are working, parenting, not seeking and not overdosing. The same logic applies to insulin in diabetes.

Do I need to detox before starting medication?

Not for buprenorphine or methadone. Buprenorphine is initiated once mild-to-moderate withdrawal has begun, to avoid precipitated withdrawal, and methadone can be started while opioids remain in the system. Only naltrexone requires being fully opioid-free first. For many patients, going directly onto medication is safer than detoxing first.

Where can I get naloxone in Orange County?

Over the counter at most pharmacies without a prescription, and free through California’s Naloxone Distribution Project and county harm-reduction programs. OC Links at (855) 625-4657 can direct you to local distribution points. Ask for the nasal spray and obtain at least two doses.

Can someone become addicted from a legitimate prescription?

It happens, though most people prescribed opioids briefly for acute pain do not develop a use disorder. Risk rises with longer duration, higher doses, personal or family history of addiction, and untreated mental health conditions. If those apply to you, disclose them before surgery so your pain plan accounts for them.

How long does opioid rehab take?

Detox is 5 to 10 days. Residential care typically runs 30 to 90 days. PHP and IOP commonly run 8 to 12 weeks, followed by ongoing outpatient care. Research consistently shows that total treatment engagement beyond roughly 90 days across all levels predicts better outcomes — the duration that matters is the whole continuum, not any single phase.

Does Premier Health Group treat opioid addiction with medication?

Yes. Medication for opioid use disorder is integrated into our care rather than treated as an alternative to it, and we coordinate prescribing across detox, residential, PHP, IOP and outpatient so the medication is not interrupted when the level of care changes.
