If you or a loved one is struggling with opioid use disorder, MAT Jacksonville programs offer one of the most evidence-based paths to long-term recovery. Medication-Assisted Treatment combines FDA-approved medications with counseling and medical oversight to reduce cravings, prevent withdrawal, and help people in Jacksonville, FL rebuild stable lives. At MedexClinic, our doctor-led opioid recovery program is directed by Dr. Asim Nouman, MD, an experienced physician with 18+ years of clinical practice in family medicine and addiction care.

This guide walks through the three FDA-approved MAT medications — buprenorphine, methadone, and naltrexone — and explains who each one is best suited for so you can have an informed conversation with your provider.

Medication-Assisted Treatment, or MAT, is the use of FDA-approved medications combined with behavioral therapy to treat opioid use disorder (OUD). Decades of clinical research show that MAT lowers overdose risk, reduces illicit opioid use, improves treatment retention, and supports return to work, school, and family life. The Substance Abuse and Mental Health Services Administration (SAMHSA) considers MAT a standard of care for moderate-to-severe opioid use disorder.

In Jacksonville, Florida — including surrounding communities like Mandarin, San Marco, Riverside, Baymeadows, Westside, Orange Park, and St. Augustine — patients have access to all three FDA-approved options through outpatient clinics, opioid treatment programs (OTPs), and primary care offices like MedexClinic.

There are three medications approved by the FDA for treating opioid use disorder. Each one works differently, and the right choice depends on your medical history, severity of dependence, lifestyle, and personal goals.

Buprenorphine is a partial opioid agonist — it activates opioid receptors enough to prevent withdrawal and cravings, but with a built-in “ceiling effect” that lowers the risk of misuse and respiratory depression compared with full opioids. It is most commonly prescribed as Suboxone (buprenorphine combined with naloxone) in film or tablet form, or as Sublocade, a monthly extended-release injection.

• How it’s taken: Daily sublingual film/tablet, or a once-monthly injection.
• Where it’s prescribed: Outpatient clinics and primary care offices — no specialty clinic required.
• Common dose range: 4 mg to 24 mg per day of sublingual buprenorphine.
• Best candidates: Adults with moderate-to-severe OUD who want flexible, office-based treatment.
• Possible side effects: Headache, constipation, nausea, sweating, insomnia.

Methadone is a long-acting full opioid agonist that has been used for opioid use disorder since the 1960s. It eliminates withdrawal and cravings when dosed correctly and has strong evidence for treatment retention, especially in patients with long histories of high-dose opioid use.

• How it’s taken: Daily oral liquid or tablet.
• Where it’s prescribed: Federally certified Opioid Treatment Programs (OTPs) only — not regular doctor’s offices.
• Common dose range: Typically 60 mg to 120 mg per day after titration.
• Best candidates: Patients with severe, long-standing opioid dependence, or those who did not stabilize on buprenorphine.
• Possible side effects: Sedation, constipation, sweating, QT-interval changes on ECG.

Naltrexone is an opioid antagonist — it blocks opioid receptors entirely, so opioids cannot produce a high. It is non-addictive and non-controlled. The extended-release injectable form, Vivitrol, is given once a month.

• How it’s taken: Daily 50 mg oral tablet, or a 380 mg intramuscular injection every 4 weeks.
• Where it’s prescribed: Any qualified medical office.
• Key requirement: Patient must be fully opioid-free for 7–14 days before the first dose to avoid precipitated withdrawal.
• Best candidates: Highly motivated patients, those leaving inpatient detox or incarceration, individuals who prefer a non-opioid medication, and people in safety-sensitive jobs.
• Possible side effects: Injection-site reactions, nausea, fatigue, headache, elevated liver enzymes.

There is no universally correct answer — the right medication is the one that fits your medical profile and supports your recovery goals. During a confidential evaluation at MedexClinic in Jacksonville, FL, your physician will review several factors:

• Severity and duration of opioid use — including the type of opioid (prescription pills, heroin, fentanyl) and daily quantity.
• Co-occurring medical conditions — liver disease, heart conditions (QT interval), pregnancy, chronic pain.
• Mental health history — depression, anxiety, PTSD, or other substance use.
• Prior treatment attempts — what worked, what didn’t, and why.
• Lifestyle and logistics — work schedule, transportation, family responsibilities, ability to attend daily dosing.
• Personal preference — some patients want a once-monthly injection; others prefer a daily medication they control at home.

For many adults beginning treatment in Northeast Florida, buprenorphine offers the right balance of effectiveness, safety, and flexibility because it can be prescribed in an office visit and taken at home. Patients who have relapsed multiple times on buprenorphine may benefit from methadone. Patients leaving detox or returning from incarceration who want a non-opioid option are often excellent candidates for Vivitrol.

No. This is one of the most persistent myths about MAT. When taken as prescribed, buprenorphine and methadone stabilize brain chemistry the same way insulin stabilizes blood sugar in diabetes — they do not produce a high in patients with established tolerance. Naltrexone produces no opioid effect at all. Multiple large studies show MAT cuts opioid overdose deaths by roughly half compared to abstinence-only approaches.

There is no fixed timeline. Some patients use MAT for 6–12 months and taper off under medical supervision; others stay on maintenance treatment for years or indefinitely. Research consistently shows that longer durations are associated with better outcomes — stopping medication too early significantly raises relapse and overdose risk. Decisions about tapering should always be made together with your physician.

Your first appointment at MedexClinic typically includes a confidential medical history, a focused physical exam, lab work, a urine drug screen, and a discussion of your treatment goals. If buprenorphine is appropriate, induction can often begin the same day or the next morning once you are in mild withdrawal. We also coordinate counseling, behavioral health support, and primary care so the whole picture of your health is addressed — not just the medication.
