Same-Day Suboxone
Treatment in North County San Diego
Physician-led MAT for opioid use disorder — private, judgment-free, and available when you are ready to start.
MAT / Suboxone in North County San Diego — Start Today
Medication-Assisted Treatment (MAT) at Oasis Medical Group combines FDA-approved Suboxone (buprenorphine/naloxone) with physician-led medical and behavioral care. It is the evidence-based standard for opioid use disorder — proven to reduce overdose risk, stop withdrawal, and help people rebuild stable lives.
Dr. Kareem Moasis, MD, and his team provide same-day and next-day access in a private North County San Diego office — not a high-volume methadone clinic. You see the same physician every visit. Your recovery stays confidential.
Whether you are dependent on fentanyl, heroin, or prescription opioids, this page explains who we treat, how intake works, what to expect at each stage, and how insurance and cash-pay options apply — so you can start with clarity, not guesswork.
What Is MAT? How Does Suboxone Work?
MAT pairs medication with medical monitoring and behavioral support. Suboxone occupies opioid receptors without producing a full opioid high — reducing cravings and withdrawal so you can focus on recovery.
Buprenorphine stabilizes brain chemistry. Naloxone deters misuse if the film is injected; when taken under the tongue as prescribed, naloxone stays inactive.
MAT is medicine — not a substitute for one addiction with another. National guidelines from SAMHSA, NIDA, and ASAM recognize MAT as the most effective approach for opioid use disorder.
At Oasis Medical Group, MAT includes:
- ✓FDA-approved Suboxone (buprenorphine/naloxone) prescribed and monitored by Dr. Moasis and his team
- ✓Same-day or next-day intake — no multi-week waitlists
- ✓Private evaluation: history, exam, urine drug screen, and California PDMP (CURES) review
- ✓Written treatment agreement with clear expectations for you and your care team
- ✓Home induction instructions with physician availability during your first doses
- ✓Weekly stabilization visits, then monthly maintenance when you are stable
- ✓Behavioral support integrated into every MAT visit — not a separate referral
- ✓Random urine monitoring for safety and dose adjustment — handled without shame
- ✓Primary care coordination: labs, chronic disease, vaccines, and referrals in one clinic
Conditions & Opioids We Treat with MAT
Opioid use disorder affects people from every background. Dr. Moasis and his team provides outpatient MAT for the situations below — with same-day intake when you are ready to start.
Fentanyl dependence
Illicit fentanyl, counterfeit pills, and prescription fentanyl patches — high-risk use requiring urgent, physician-led MAT.
Heroin & illicit opioids
Injection or inhalation use; stabilization with Suboxone to stop withdrawal and reduce overdose risk.
Prescription opioid dependence
Oxycodone, hydrocodone, morphine, codeine, tramadol, and other prescribed opioids used beyond medical need.
Opioid use disorder (OUD)
Formal diagnosis per clinical criteria — cravings, loss of control, and continued use despite harm.
Polysubstance use
Opioids combined with alcohol, benzodiazepines, or stimulants — evaluated for safe MAT initiation.
Post-overdose & relapse recovery
Restarting or continuing MAT after overdose, detox, incarceration, or a period without treatment.
Co-occurring medical conditions
High blood pressure, diabetes, hepatitis C, chronic pain, pregnancy planning — managed alongside MAT in-office.
Co-occurring mental health
Anxiety, depression, PTSD, and insomnia addressed with integrated behavioral support at every visit.

Our MAT / Suboxone Treatment Process
From your first call through long-term recovery — here is how Suboxone treatment works at Oasis Medical Group in North County San Diego.
Step 1 — Call for same-day or next-day access
Call 760-691-1901 when you are ready. We prioritize new MAT patients — most people are seen the same day or next day. No long waitlists.
Step 2 — Private intake evaluation
Dr. Moasis and his team review your history, health, goals, PDMP (CURES), and a urine drug screen. Everything is confidential and handled without judgment.
Step 3 — Diagnosis & treatment plan
Opioid use disorder is diagnosed using standard clinical criteria. You receive a clear plan — medication, visit schedule, and behavioral support built in.
Step 4 — Suboxone induction
Most patients start at home once in mild to moderate withdrawal, with step-by-step instructions from Dr. Moasis and his team. Many feel relief within hours of the first dose.
Step 5 — Stabilization (weeks 1–4)
Weekly visits focus on dose adjustment, side effects, cravings, and recovery skills. Urine monitoring supports safety — not punishment.
Step 6 — Maintenance & long-term recovery
Stable patients transition to monthly visits. Dr. Moasis and his team continues medical care, behavioral support, and optional taper planning when you are ready.
Step 7 — Recovery planning & optional taper
When you are ready, we build a gradual taper plan together — no fixed timeline and no pressure. Many patients choose long-term maintenance because outcomes improve with sustained MAT.
What to Expect
Knowing what happens before, during, and after your first dose reduces anxiety and helps you start safely.
Before your first visit
- Bring a valid ID and insurance card if you have one.
- Be honest about what you have used and when — accuracy keeps you safe.
- If you are actively using opioids, do not stop abruptly without medical guidance.
- Plan 45–60 minutes for your first appointment.
At your first appointment
- Private exam room — not a crowded clinic lobby.
- Discussion of your goals, triggers, and medical history with Dr. Moasis and his team.
- Urine drug screen and prescription monitoring (PDMP) review.
- Clear instructions for when and how to take your first Suboxone dose.
Starting Suboxone (induction)
- You must be in mild to moderate withdrawal before the first dose — starting too early can cause precipitated withdrawal.
- Typical starting dose is low (often 2–4 mg buprenorphine/naloxone) and adjusted based on response.
- Most patients report reduced cravings and withdrawal within the first day.
- Dr. Moasis and his team is available if you have questions during induction.
Ongoing MAT visits
- Weekly visits early on, then monthly when stable.
- Integrated behavioral support at every visit — not a separate referral.
- Random urine drug screens to track progress and adjust care.
- Coordinated primary care for blood pressure, diabetes, hepatitis, mental health, and more.
Behavioral Support — Built Into Every MAT Visit
Suboxone stabilizes your brain chemistry. Behavioral support helps you rebuild a life worth protecting — and at Oasis, both happen in the same private office with Dr. Moasis and his team.
You are not sent to a separate counseling center or placed on a waitlist for therapy. Evidence-based techniques are integrated into your MAT appointments, including:
Motivational interviewing
Collaborative conversations that strengthen your own reasons for change — without lectures or pressure.
Cognitive behavioral techniques
Identify triggers, thought patterns, and practical skills to manage cravings and high-risk situations.
Relapse prevention planning
Personalized coping tools and action plans for moments when urges feel overwhelming.
Supportive counseling
Stress, relationships, sleep, and emotional recovery addressed during your regular MAT visits.

FAQ
MAT & Suboxone FAQs
Answers to common questions about eligibility, process, and what to expect.
Adults with opioid use disorder who want physician-led, outpatient treatment are generally eligible. Dr. Moasis and his team evaluates each patient individually — including medical history, current opioid use, pregnancy status, and other medications. Same-day intake is available for most new patients. Call 760-691-1901 to discuss your situation confidentially.
In most cases, yes. We offer same-day and next-day appointments because motivation to start treatment is time-sensitive. Your first visit includes evaluation and a plan; induction timing depends on whether you are already in withdrawal and medically ready to begin.
Yes. Starting Suboxone before mild to moderate withdrawal can trigger precipitated withdrawal — sudden, severe symptoms. Dr. Moasis and his team gives you clear timing instructions for home induction so your first dose is safe and effective.
Expect a private, unhurried visit with Dr. Moasis and his team: history, exam, urine screen, PDMP review, diagnosis discussion, and a written treatment agreement. You will leave with a concrete plan — not a referral to wait weeks elsewhere.
There is no fixed timeline. Some patients taper after months; others benefit from longer maintenance. Research shows longer MAT duration improves outcomes. Dr. Moasis and his team partners with you on goals — no pressure to taper before you are ready.
When taken as prescribed for opioid dependence, Suboxone does not produce a high. Most patients work, drive, and parent normally. MAT is designed to restore stability — not sedate you.
Yes. Your care is protected by HIPAA and additional federal privacy rules (42 CFR Part 2) for substance use treatment records. Oasis is a private medical office — not a public program.
We accept most major PPO plans, Medicare, and Tricare. Cash-pay membership options are available. We do not accept Medi-Cal or Medicaid for MAT at this time. Call 760-691-1901 to verify benefits before your visit.
Relapse does not mean you are discharged. Dr. Moasis and his team adjusts your plan, addresses triggers, and continues care. Recovery is rarely linear — we treat it as a medical process, not a moral failure.
We treat opioid use disorder related to fentanyl, heroin, prescription pain pills (oxycodone, hydrocodone, and others), and polysubstance use when medically appropriate. Many patients also receive primary care and mental health support in the same clinic.
Cash-pay membership plans start at $399/month (Starter), $499/month (Core), and $599/month (Premium), with transparent pricing discussed before you enroll. Call 760-691-1901 for details and to verify insurance benefits if you have coverage.
