Fentanyl is a synthetic opioid many times more potent than heroin, and its potency is what makes it different in practice. Doses that matter are small enough that mixing is uneven, so two pills from the same batch can differ. That is why overdoses happen to experienced users who did nothing differently.

Golden Coast Rehab treats fentanyl use disorder in adults across San Diego County on an outpatient basis. Many people we see did not set out to use fentanyl at all — they were using pills, and the pills contained it.

If you use, carry naloxone, do not use alone, and treat every unknown pill as potentially lethal. Those three things keep people alive long enough to get to treatment.

How fentanyl use disorder is treated here

Golden Coast Rehab holds California Department of Health Care Services (DHCS) substance use disorder certification 370254AP for outpatient detoxification, outpatient, intensive outpatient, and medication-assisted treatment. We do not provide residential or inpatient treatment, and there is no substance use partial hospitalization program here — partial hospitalization at Golden Coast Rehab is a specialty mental health service under our County of San Diego contract.

Outpatient detox

Withdrawal from fentanyl can come on fast and hard, and because fentanyl behaves differently in the body than other opioids, starting medication requires care and timing. That is a clinical conversation, not something to improvise. The assessment determines whether outpatient withdrawal management is safe for you.

Medication-assisted treatment

Medication is the central treatment for fentanyl use disorder and the intervention with the clearest effect on overdose death. Because of how fentanyl accumulates in body tissue, the timing of starting medication needs clinical management — another reason not to attempt this alone.

Intensive outpatient program

The core of treatment: several sessions a week of group and individual therapy while you live at home and, in most cases, keep working. This is where the actual work on triggers, craving, and the life around the using happens.

Outpatient program

A lighter weekly schedule that follows intensive outpatient and keeps the clinical relationship intact through the first year, when relapse risk is highest.

Common Signs of Fentanyl Use

With fentanyl, the signs that matter most are the ones tied to overdose risk.

01.highAny overdose, witnessed or survived

Being revived with naloxone, or waking up not knowing what happened.

Health Risks: A survived overdose is among the strongest predictors of a subsequent fatal one. This is an emergency-level signal for treatment.

02.highUsing alone

No one present who could recognize an overdose or administer naloxone.

Health Risks: Most fatal overdoses happen with nobody there. Never using alone is the single highest-value change available.

03.highUsing pills of unknown origin

Anything not dispensed by a pharmacy, however pharmaceutical it looks.

Health Risks: Counterfeit pills commonly contain fentanyl at inconsistent doses; appearance tells you nothing.

04.moderateWithdrawal arriving faster than it used to

Needing to use more frequently through the day to stay ahead of being sick.

Health Risks: Escalating frequency signals rising dependence and rising exposure risk.

05.moderateTolerance that keeps climbing

Amounts rising quickly, with a shrinking margin between the dose that works and the dose that stops your breathing.

Health Risks: With fentanyl, that margin is small to begin with.

When a mental health condition is also present

Depression, anxiety, trauma, and bipolar disorder frequently sit alongside a substance use disorder, and treating only one of them is the most reliable way to end up back where you started. Both are treated here by one clinical team — see dual diagnosis, or the same care framed from the mental health side on co-occurring disorders.

Coverage and cost

Substance use treatment for Medi-Cal beneficiaries in San Diego County runs through the Drug Medi-Cal Organized Delivery System, administered by San Diego County Behavioral Health Services rather than by your managed care plan. If you have Medi-Cal in the county — any of the four plans — and you meet criteria, care here can be covered at no cost to you. See how Medi-Cal works here.

Questions, Answered

FAQs About Fentanyl Addiction

Can fentanyl use disorder be treated as an outpatient?
For many people, yes — with medication, counseling, and close follow-up. The assessment determines whether outpatient care is safe in your case, and if it is not, we will say so and help you get to the right level.
Is stopping fentanyl dangerous?
Withdrawal itself is rarely fatal, but relapse after any period of abstinence is extremely dangerous because tolerance drops fast while supply potency does not. That is exactly why treatment includes medication rather than willpower alone.
Why does starting medication need special timing with fentanyl?
Fentanyl persists in the body differently from other opioids, which affects when medication can be started comfortably and safely. This is a clinical judgment we make with you rather than a fixed rule.
I only use pills, not fentanyl. Does this page apply to me?
Probably, yes. Counterfeit pills sold as prescription opioids or benzodiazepines frequently contain fentanyl. If your supply is not from a pharmacy, assume the risk applies.
Where do I get naloxone?
Naloxone is available without a prescription at pharmacies in California and through county and community distribution programs. The San Diego County Access and Crisis Line at 1-888-724-7240 can point you to local resources.
Does Medi-Cal cover treatment?
Yes. Fentanyl use disorder treatment is covered under the county's Drug Medi-Cal system, with no out-of-pocket cost for most members and no plan-switching required.
How many overdose deaths involve fentanyl?
NIDA reports 72,776 U.S. overdose deaths involving synthetic opioids, primarily illicitly manufactured fentanyl, in 2023. Because fentanyl is so potent and increasingly found mixed into other drugs, medical detox and close monitoring are especially important when starting treatment. Locally, CDPH's overdose dashboard counts 384 fentanyl-related overdose deaths in San Diego County in 2024.
Why is fentanyl treated differently from other opioids here?
Fentanyl's potency and how long it stays in fat tissue change the timing of when medication can safely start, which is exactly why that assessment step gets extra attention. The underlying treatment options — outpatient detox, MAT, IOP — are the same ones used for other opioids.
Can I get naloxone if I don't want treatment yet?
Naloxone access does not require you to enroll in treatment — ask us or contact county harm reduction resources directly. Having it on hand is a safety measure regardless of where you are in deciding about treatment.
Do you provide residential fentanyl detox?
No — Golden Coast Rehab does not provide residential or inpatient treatment. Fentanyl-related detox and treatment here are delivered outpatient, with the assessment determining whether that's safe for your specific situation.
What if I've overdosed before?
That history matters and gets factored directly into your assessment and treatment plan — it is not something that disqualifies you from care, it's information we need to keep you safer going forward.
How do I know if what I'm using has fentanyl in it?
You often can't tell by appearance, taste, or effect alone — fentanyl test strips are the only reliable way to check, and we can point you to where to get them. Treat anything not from a pharmacy as a possible fentanyl exposure.
