Recovery Is Possible — And It Starts Here
If you or someone you love is struggling with opioid dependence, you already know how exhausting and isolating it can feel. The cravings. The withdrawals. The cycle that seems impossible to break no matter how hard you try. You are not weak. You are not a lost cause. You are dealing with a medical condition — and like every medical condition, it responds to the right treatment.
Suboxone treatment at Oasis Medical Group in Vista, California is that treatment.
Dr. Kareem Moasis, MD, and his team provides private, physician-led Suboxone treatment combined with behavioral support to help patients safely and effectively recover from opioid use disorder. Whether you are dependent on fentanyl, heroin, oxycodone, hydrocodone, or any other opioid — we can help you stabilize, stop the cycle, and start building the life you want back.
Same-day and next-day appointments are available. No waitlists. No judgment. No lectures. Just real medical care from a physician who understands addiction as the complex brain disease it truly is.
What Is Suboxone and How Does It Work?
Suboxone is a prescription medication that contains two active ingredients — buprenorphine and naloxone. It is FDA-approved specifically for the treatment of opioid use disorder and is one of the most effective and well-studied medications available for addiction medicine.
Buprenorphine is a partial opioid agonist. This means it binds to the same receptors in your brain that opioids target — but without producing the intense high. It works by reducing cravings and eliminating withdrawal symptoms, allowing your brain chemistry to stabilize while you focus on your recovery. Think of it as giving your brain the signal it needs without the damage.
Naloxone is the second ingredient and acts as a safety mechanism. It is included to deter misuse — if Suboxone is tampered with or injected rather than dissolved under the tongue, the naloxone activates and blocks all opioid effects immediately. When taken as prescribed, the naloxone remains inactive.
Together these two ingredients create a medication that is safe, effective, and designed to support long-term recovery rather than simply masking symptoms. Suboxone does not get you high. It does not replace one addiction with another. It gives your brain and body the stability to heal.
What Is Medication-Assisted Treatment (MAT)?
Medication-Assisted Treatment — commonly called MAT — is the evidence-based approach to treating opioid use disorder that combines FDA-approved medications like Suboxone with behavioral support and counseling.
Decades of clinical research confirm that MAT is significantly more effective than willpower alone, detox without medication, or abstinence-only approaches. The National Institute on Drug Abuse, the Substance Abuse and Mental Health Services Administration, and the American Society of Addiction Medicine all recognize MAT as the gold standard treatment for opioid use disorder.
At Oasis Medical Group, MAT means you receive:
- ✓Suboxone to stabilize cravings and eliminate withdrawal
- ✓Behavioral support integrated into every visit with Dr. Moasis and his team
- ✓Personalized treatment planning based on your specific situation, substance history, and recovery goals
- ✓Regular monitoring to ensure your medication is working and your plan is adjusted as needed
- ✓Compassionate, physician-led care in a private office setting — not a clinic waiting room
MAT is not a shortcut. It is medicine. And it works.
Signs You or Someone You Love May Need Suboxone Treatment
Opioid use disorder affects people from every background, income level, age group, and walk of life. You may benefit from Suboxone treatment if you or someone close to you is experiencing:
- ✓Inability to stop using opioids despite wanting to
- ✓Spending significant time and energy obtaining, using, or recovering from opioids
- ✓Physical withdrawal symptoms when opioids are not taken — sweating, chills, nausea, vomiting, muscle aches, insomnia
- ✓Increasing tolerance — needing more of the drug to feel the same effect
- ✓Continued use despite negative consequences in relationships, work, or health
- ✓Failed attempts to quit or cut back on your own
- ✓Using opioids to avoid withdrawal rather than to feel good
- ✓Neglecting responsibilities, hobbies, or relationships because of opioid use
- ✓Obtaining opioids illegally or using medications prescribed to someone else
- ✓Fear of running out of opioids or planning your day around access to them
If several of these sound familiar — please reach out. You are not alone and this is treatable.
How Suboxone Treatment Works at Oasis Medical Group
Dr. Moasis and his team have designed the Suboxone program at Oasis to be as accessible, comfortable, and effective as possible. Here is exactly what the process looks like from your very first call.
Step 1 — Same-Day or Next-Day Consultation
Call 760-691-1901 and we will get you scheduled immediately — same day or next day in most cases. You do not need to go through a long intake process or wait weeks to be seen. The sooner you come in, the sooner we can help.
Step 2 — Comprehensive Intake Evaluation
At your first appointment Dr. Moasis and his team conduct a thorough evaluation including your substance use history, current health status, any co-occurring medical or mental health conditions, and your recovery goals. He reviews the PDMP (California's CURES prescription database) and collects a urine drug screen. This gives him a complete picture of your situation.
Step 3 — Diagnosis and Treatment Agreement
Dr. Moasis and his team establishes a formal diagnosis of opioid use disorder using DSM-5 criteria and discusses your treatment agreement with you. This outlines the expectations of the program, your responsibilities as a patient, and what you can expect from Dr. Moasis and his team and the Oasis team.
Step 4 — Suboxone Induction
Most patients begin with home induction — meaning you start your first dose at home once you are in mild to moderate withdrawal. Dr. Moasis and his team provide clear, detailed instructions. Starting dose is typically 2–4mg of buprenorphine/naloxone, titrated upward based on your response. Many patients feel significantly better within the first few hours of their first dose.
Step 5 — Stabilization Phase (Weeks 1–4)
During the first month you attend weekly visits with Dr. Moasis and his team. These appointments focus on dose adjustment, monitoring your response, addressing any side effects, and providing behavioral support. Regular urine drug screens are performed to monitor your progress.
Step 6 — Maintenance Phase
Once you are stable on your dose, visits transition to monthly. Dr. Moasis and his team continues to monitor your progress, perform random drug screens, and provide ongoing behavioral support. The goal during maintenance is long-term stability and quality of life — not just absence of opioid use.
Step 7 — Long-Term Recovery Planning
When you and Dr. Moasis and his team agree the time is right, he will work with you on a careful, gradual tapering plan if that is your goal. There is no pressure and no timeline imposed on you. Recovery is not one-size-fits-all.
Behavioral Support — Why It Matters
Suboxone alone is powerful. Suboxone combined with behavioral support is transformative.
At Oasis, behavioral support is integrated into every MAT visit — it is not an add-on or a referral to somewhere else. Dr. Moasis and his team incorporates evidence-based behavioral techniques including:
Motivational Interviewing
A collaborative conversation style that helps you explore your own reasons for change, resolve ambivalence, and strengthen your commitment to recovery without judgment or pressure.
Cognitive Behavioral Techniques
Identifying thought patterns and behavioral triggers that contribute to cravings and relapse risk, then developing practical strategies to manage them.
Relapse Prevention Planning
Building a personalized toolkit of coping strategies, identifying high-risk situations, and creating an action plan for moments when cravings feel overwhelming.
Supportive Counseling
Stress management, coping with life challenges, rebuilding relationships, and addressing the emotional dimensions of recovery.
This integrated approach is why outcomes at Oasis exceed what medication alone can achieve. Recovery is not just about stopping opioids — it is about rebuilding a life worth staying sober for.

Suboxone Treatment FAQs
There is no universal timeline. Some patients stabilize and taper within months. Others benefit from longer-term maintenance — sometimes years. Research consistently shows that longer duration of MAT leads to better outcomes. Dr. Moasis and his team will discuss your individual goals and help you make the decision that is right for your recovery — not what fits a predetermined schedule.
No. When taken as prescribed by a patient with opioid dependence, Suboxone does not produce euphoria or a high. It occupies opioid receptors and stabilizes your brain chemistry without the intoxicating effects of full opioid agonists. Most patients describe feeling normal — clear-headed, stable, and able to function.
Absolutely — and that is exactly the point. MAT is designed to allow you to return to your life. Patients on Suboxone work full-time jobs, care for their families, drive, and engage fully in daily activities. The medication is taken once daily and does not impair cognitive or physical function when used as prescribed.
Because buprenorphine binds strongly to opioid receptors, using additional opioids while on Suboxone typically results in little to no effect from the additional opioids — which reduces the reward of using. Urine drug screens are a standard part of the program and any positive results are addressed openly and without punishment as part of your treatment plan.
Yes. Your treatment is protected by HIPAA and additionally by 42 CFR Part 2 — a federal regulation providing extra privacy protections specifically for substance use disorder treatment records. Your information is never shared without your explicit written consent.
Yes — starting Suboxone before you are in at least mild to moderate withdrawal can trigger precipitated withdrawal which is extremely uncomfortable. Dr. Moasis and his team provide detailed instructions on timing your first dose correctly. Most patients begin home induction once they are experiencing early withdrawal symptoms.
Relapse is a common part of the recovery process for many people — not a moral failure or a reason to give up. If you relapse, Dr. Moasis and his team works with you to understand what happened, adjust your treatment plan if necessary, and continue moving forward. You will not be discharged from the program for a relapse. Recovery is not a straight line and we understand that.
