Medication-Assisted Treatment (MAT): What It Is & How It Works

What Is Medication-Assisted Treatment?

Medication-assisted treatment (MAT) combines FDA-approved medications with counseling and behavioral therapies to treat substance use disorders. MAT is considered the gold standard of care for opioid use disorder and alcohol use disorder, backed by decades of clinical research demonstrating significantly better outcomes than treatment without medication.

Despite strong evidence for its effectiveness, MAT remains misunderstood and stigmatized in many communities. Understanding what MAT is — and what it isn’t — helps people make informed decisions about treatment.

MAT for Opioid Use Disorder

Three FDA-approved medications are used for opioid use disorder:

Buprenorphine (Suboxone, Subutex)

Buprenorphine is a partial opioid agonist — it activates opioid receptors but only partially, producing effects that prevent withdrawal and cravings without the euphoria of full opioids. Its “ceiling effect” makes it safer than full agonists, with a lower risk of overdose.

Suboxone combines buprenorphine with naloxone (an opioid blocker) to deter misuse. It is taken sublingually (dissolved under the tongue) once daily or every other day. Buprenorphine can be prescribed by certified physicians, NPs, and PAs in office-based settings — making it widely accessible.

Methadone

Methadone is a long-acting full opioid agonist that eliminates withdrawal symptoms and cravings. It must be dispensed through federally certified opioid treatment programs (OTPs), meaning daily visits to a clinic are required initially. As patients demonstrate stability, take-home doses are allowed.

Methadone has over 50 years of clinical evidence supporting its effectiveness for opioid use disorder and has been shown to reduce opioid-related mortality by more than 50%.

Naltrexone (Vivitrol)

Naltrexone is an opioid antagonist — it completely blocks opioid receptors, meaning opioids have no effect while the medication is active. It does not produce any opioid effect and carries no abuse potential. Extended-release injectable naltrexone (Vivitrol) is administered monthly by a healthcare provider, eliminating daily dosing challenges.

Naltrexone requires complete detox from opioids before starting — typically 7–10 days minimum — making it inappropriate for people still in active withdrawal.

MAT for Alcohol Use Disorder

Three medications are FDA-approved for alcohol use disorder:

Naltrexone (oral or injectable)

Naltrexone reduces the pleasurable effects of alcohol and diminishes cravings. Both oral (daily) and injectable (monthly) formulations are available. Clinical studies show significant reduction in heavy drinking days and rates of relapse.

Acamprosate (Campral)

Acamprosate helps restore balance to neurotransmitter systems disrupted by long-term alcohol use, reducing the anxiety and dysphoria that drive relapse during early recovery. It is most effective after detox is complete and the person has achieved sobriety.

Disulfiram (Antabuse)

Disulfiram creates an unpleasant physical reaction when alcohol is consumed — nausea, flushing, rapid heartbeat — creating a strong deterrent to drinking. It is most effective when compliance is supervised.

Common Misconceptions About MAT

“MAT is just substituting one drug for another.” This is the most common misconception. MAT medications are prescribed by physicians for a medical condition. They stabilize brain chemistry, reduce cravings and withdrawal, allow people to function normally, and dramatically reduce overdose risk. The evidence is clear: people on MAT have better outcomes across every measured domain — employment, family stability, reduced criminal justice involvement, and most critically, survival.

“You’re not really in recovery if you’re on MAT.” Major recovery organizations, including SAMHSA and most clinical bodies, recognize MAT as a legitimate, evidence-based path to recovery. Recovery is defined by the individual’s quality of life and ability to function — not by which medications they take.

“MAT is forever.” MAT duration is individualized. Some people use MAT for months; others for years. The decision about when and whether to taper is made collaboratively between patient and provider based on clinical stability and readiness.

MAT as Part of a Complete Treatment Plan

Medication alone is not the complete picture. MAT is most effective when combined with counseling, behavioral therapies, peer support, and other recovery services. The “assisted” in medication-assisted treatment means exactly that — the medication assists the recovery process, it does not replace it.

If you’re interested in learning whether MAT might be appropriate for your situation, speaking with a clinical specialist is the best first step. Call for a free, confidential conversation — no obligation.
