Understanding Medication-Assisted Treatment (MAT)
Medication-Assisted Treatment (MAT) combines FDA-approved medications with counseling and behavioral therapies to treat substance use disorders. According to SAMHSA, MAT is the gold-standard treatment for opioid use disorder and is also effective for alcohol use disorder.
Despite strong evidence supporting its effectiveness, MAT remains underutilized due to stigma and misconceptions. Many people worry that taking medication for addiction means 'trading one drug for another.' This guide addresses those concerns with facts from trusted sources.
Whether you're considering MAT for yourself or trying to understand a loved one's treatment options, this article explains how these medications work, who can benefit, and what to expect. For related information, see our guides on what happens during medical detox and the fentanyl crisis.
What Is Medication-Assisted Treatment?
Medication-Assisted Treatment (MAT) is an evidence-based approach that uses FDA-approved medications in combination with counseling and behavioral therapies. According to NIDA, this combination addresses both the physical and psychological aspects of addiction, making it more effective than either approach alone.
MAT is primarily used for opioid use disorder (addiction to heroin, fentanyl, or prescription painkillers) and alcohol use disorder. The medications work differently depending on the substance, but they share a common goal: reducing cravings, preventing withdrawal symptoms, and allowing people to focus on recovery.
Research consistently shows that MAT improves outcomes. According to the CDC, people receiving MAT for opioid use disorder are significantly more likely to stay in treatment and less likely to use illicit opioids or die from overdose compared to those receiving treatment without medication.
Key point
MAT is not a replacement for counseling or therapy — it works alongside these treatments. The medication addresses the biological aspects of addiction while therapy addresses behavioral patterns, triggers, and underlying issues.
The Three FDA-Approved Medications for Opioid Use Disorder
Three medications are currently approved by the FDA for treating opioid use disorder. Each works differently, and the best choice depends on individual circumstances, preferences, and treatment history.
Buprenorphine (Suboxone, Subutex, Sublocade)
Buprenorphine is a partial opioid agonist, meaning it activates opioid receptors in the brain but produces a much weaker effect than full opioids like heroin or fentanyl. This partial activation relieves cravings and withdrawal symptoms without producing the intense high of illicit opioids.
Most buprenorphine formulations also contain naloxone (Suboxone), which discourages misuse. If someone tries to inject the medication, the naloxone causes immediate withdrawal symptoms. When taken as prescribed (dissolved under the tongue), the naloxone has minimal effect.
- Administration: Sublingual tablets, dissolvable films, or monthly injection (Sublocade)
- Prescribing: Can be prescribed by any licensed provider (DEA X-waiver requirement removed in 2023)
- Advantages: Can be prescribed in regular medical settings, lower overdose risk, take-home doses possible
- Considerations: May not be sufficient for people with high opioid tolerance, requires some withdrawal before starting
Methadone
Methadone is a full opioid agonist that has been used to treat opioid addiction since the 1960s. It fully activates opioid receptors, preventing withdrawal and reducing cravings. Because it's taken orally and works slowly, it doesn't produce the rush associated with injected opioids.
Unlike buprenorphine, methadone must be dispensed through certified Opioid Treatment Programs (OTPs). Patients typically start with daily visits to the clinic, with the possibility of take-home doses as they demonstrate stability in recovery.
- Administration: Daily oral liquid or tablets at a certified clinic
- Prescribing: Only through certified Opioid Treatment Programs (OTPs)
- Advantages: Highly effective for severe opioid dependence, long track record, structured support at clinics
- Considerations: Daily clinic visits initially required, higher overdose risk than buprenorphine if misused, may cause sedation
Naltrexone (Vivitrol)
Naltrexone is an opioid antagonist — it blocks opioid receptors entirely. Unlike buprenorphine and methadone, it produces no opioid effects whatsoever. If someone takes opioids while on naltrexone, they will not feel any effect because the receptors are blocked.
This medication is typically administered as a monthly injection (Vivitrol), though oral tablets are also available. Because naltrexone is a blocker, it requires complete detoxification before starting — usually 7-14 days without opioids.
- Administration: Monthly injection (Vivitrol) or daily tablets
- Prescribing: Any licensed healthcare provider
- Advantages: No opioid effects, no risk of diversion, monthly injection ensures compliance
- Considerations: Requires complete detox first (often the hardest part), does not relieve cravings as effectively as agonist medications
How MAT Works in the Brain
To understand why MAT is effective, it helps to understand what opioids do to the brain. When someone uses opioids repeatedly, the brain adapts by reducing its own production of natural 'feel-good' chemicals and becoming less sensitive to them. This is why people need more and more of the substance to feel normal — and why they feel terrible without it.
MAT medications work by interacting with the same brain receptors as illicit opioids, but in a controlled, stable way. Buprenorphine and methadone keep the receptors partially or fully occupied, preventing withdrawal and reducing the intense cravings that drive relapse. Naltrexone blocks the receptors entirely, so even if someone uses opioids, there's no rewarding effect.
Over time, with the medication providing stability, the brain can begin to heal. The goal is to give people the mental clarity and physical stability they need to engage in counseling, rebuild their lives, and develop recovery skills — without being derailed by constant cravings or fear of withdrawal.
Helpful analogy
Think of MAT like insulin for diabetes. Diabetes involves the body's inability to regulate blood sugar properly. Similarly, opioid addiction involves changes in brain chemistry that make self-regulation extremely difficult. Medication helps restore balance so other treatments can work.
Addressing Common Concerns About MAT
Despite decades of research supporting MAT, misconceptions persist. These concerns often prevent people from accessing a treatment that could save their lives.
"Isn't this just trading one drug for another?"
This is the most common concern — and the most misunderstood. The key difference is stability versus chaos. Illicit opioid use involves constantly fluctuating drug levels, risk of overdose, illegal activity, and inability to function normally. MAT provides steady medication levels that prevent withdrawal and cravings without impairing daily functioning.
According to SAMHSA, people on MAT can work, care for their families, and participate fully in life. They're not 'high' — they're stable. Research consistently shows that MAT reduces illicit drug use, criminal activity, and overdose deaths while improving employment and quality of life.
"How long do people stay on MAT?"
There is no 'right' duration for MAT. Some people take medication for a year or two, while others benefit from long-term or lifelong treatment. According to NIDA, longer durations of treatment are associated with better outcomes, and the decision to taper should be individualized.
The focus should be on stability and quality of life, not on reaching an arbitrary end date. Many healthcare providers compare this to treatment for other chronic conditions — you don't set a deadline to stop blood pressure medication just because you've been taking it for a year.
"Is MAT real recovery?"
Yes. SAMHSA defines recovery as 'a process of change through which individuals improve their health and wellness, live self-directed lives, and strive to reach their full potential.' Nowhere does this definition exclude medication.
Taking prescribed medication for a medical condition is not the same as active addiction. Active addiction involves compulsive use despite harmful consequences, loss of control, and continued use to feel high. MAT involves taking a prescribed medication as directed to support health and functioning — the opposite of active addiction.
MAT for Alcohol Use Disorder
While MAT is most commonly discussed for opioid addiction, three FDA-approved medications also treat alcohol use disorder. These medications are underutilized — according to research, fewer than 10% of people with alcohol use disorder receive any medication, despite strong evidence of effectiveness.
Naltrexone (ReVia, Vivitrol)
The same medication used for opioid use disorder also helps with alcohol. Naltrexone reduces the pleasurable effects of alcohol by blocking opioid receptors (alcohol's rewarding effects partly involve the opioid system). People taking naltrexone often report that drinking feels less satisfying, making it easier to cut back or stop.
- Available as daily tablets (ReVia) or monthly injection (Vivitrol)
- Does not cause sickness if you drink — it simply reduces the rewarding effects
- Can be started while someone is still drinking (does not require abstinence first)
Acamprosate (Campral)
Acamprosate helps restore the brain's chemical balance after someone stops drinking. Chronic alcohol use disrupts brain chemistry, and acamprosate helps normalize these systems, reducing the discomfort and cravings that can lead to relapse.
- Taken as tablets three times daily
- Most effective when started after detox, once someone has stopped drinking
- Works differently than naltrexone — some people respond better to one or the other
Disulfiram (Antabuse)
Disulfiram works differently from other alcohol medications. It causes very unpleasant physical reactions (flushing, nausea, rapid heartbeat) if someone drinks alcohol while taking it. This aversive effect serves as a strong deterrent to drinking.
Because it requires strict abstinence, disulfiram works best for highly motivated individuals with strong support systems.
- Taken as a daily tablet
- Any alcohol consumption while taking it causes immediate, unpleasant symptoms
- Best for people who are committed to abstinence and want an extra safeguard
Finding MAT Providers
Access to MAT has expanded significantly in recent years, but finding a provider can still be challenging depending on location. Here are resources and tips for finding MAT treatment.
- SAMHSA Treatment Locator: Visit findtreatment.gov or call 1-800-662-4357 to find providers in your area
- Telehealth options: Many providers now offer MAT via telehealth, expanding access for those in rural or underserved areas
- Primary care offices: With the removal of the X-waiver requirement in 2023, more primary care doctors can prescribe buprenorphine
- Opioid Treatment Programs: For methadone treatment, search for certified OTPs through SAMHSA's locator
Questions to ask providers
When contacting a potential provider, ask: What medications do you offer? What counseling is included? Do you accept my insurance? What is the expected treatment duration? Is telehealth available? These questions help ensure the provider meets your needs.
MAT as Part of Comprehensive Treatment
Medication alone is not complete treatment. According to SAMHSA, the 'treatment' part of MAT refers to the combination of medication AND counseling or behavioral therapy. Research shows that combining medication with therapy produces better outcomes than either approach alone.
The medication creates stability and reduces cravings, making it possible to engage meaningfully in therapy. Meanwhile, therapy addresses the behavioral patterns, emotional issues, and life circumstances that contribute to addiction.
- Individual counseling: One-on-one sessions addressing personal triggers, coping skills, and underlying issues
- Group therapy: Peer support and shared learning in a structured setting
- Cognitive Behavioral Therapy (CBT): Identifying and changing thought patterns that lead to substance use
- Contingency management: Positive reinforcement for meeting treatment goals
- Support groups: 12-step programs, SMART Recovery, or other peer support
- Case management: Help with housing, employment, and other life needs
Important
Some treatment facilities and recovery communities do not support MAT. If you're seeking residential treatment or a support group, ask about their medication policies before enrolling to ensure you'll receive appropriate care.
