What Is Medication-Assisted Treatment (MAT)?

Medication-Assisted Treatment, commonly known as MAT, is one of the most significant advances in addiction medicine. It combines FDA-approved medications with counseling and behavioral therapies to provide a “whole-patient” approach to treating substance use disorders. Despite strong evidence supporting its effectiveness, MAT remains widely misunderstood — and that misunderstanding costs lives.

This article explains what MAT is, how it works, which medications are used, and why it represents the gold standard of care for opioid and alcohol use disorders.

Understanding Medication-Assisted Treatment

MAT is not simply “replacing one drug with another.” This common misconception prevents many people from accessing treatment that could save their lives. MAT medications are FDA-approved, clinically tested, and prescribed under medical supervision. They work by normalizing brain chemistry, blocking the euphoric effects of substances, relieving cravings, and normalizing body functions — without the dangerous highs and lows of active addiction.

According to the Substance Abuse and Mental Health Services Administration (SAMHSA), MAT has been clinically proven to:

• Reduce opioid use and opioid-related overdose deaths
• Increase treatment retention
• Decrease criminal activity associated with substance use
• Improve birth outcomes for pregnant women with substance use disorders
• Reduce the risk of contracting HIV and hepatitis C
• Improve social functioning and employment outcomes

Medications Used in MAT

For Opioid Use Disorder

Three medications are currently FDA-approved for treating opioid use disorders:

Buprenorphine (Suboxone, Sublocade, Zubsolv): A partial opioid agonist that reduces cravings and withdrawal symptoms without producing the full euphoric effects of opioids. Buprenorphine can be prescribed in office-based settings by qualified healthcare providers, making it widely accessible. It has a “ceiling effect” that reduces the risk of misuse, respiratory depression, and overdose.

Methadone: A long-acting full opioid agonist that reduces cravings and withdrawal symptoms. Methadone has been used for over 50 years and has the longest track record of any MAT medication. It must be dispensed through SAMHSA-certified opioid treatment programs (OTPs), though recent policy changes have expanded take-home dosing flexibility.

Naltrexone (Vivitrol): An opioid antagonist that blocks the effects of opioids entirely. Unlike buprenorphine and methadone, naltrexone has no opioid effects and no potential for misuse. It’s available as a monthly injection (Vivitrol), which eliminates daily dosing compliance issues. The individual must be fully detoxed from opioids before starting naltrexone.

For Alcohol Use Disorder

Three medications are FDA-approved for alcohol use disorder:

Naltrexone (ReVia, Vivitrol): Blocks the rewarding effects of alcohol, reducing cravings and the pleasure associated with drinking. Available as a daily oral tablet or monthly injection.

Acamprosate (Campral): Helps restore the balance of neurotransmitters in the brain that are disrupted by chronic alcohol use. It’s most effective for maintaining abstinence after detox and is typically started after the individual has stopped drinking.

Disulfiram (Antabuse): Causes unpleasant physical reactions (nausea, flushing, headache) when alcohol is consumed, serving as a deterrent to drinking. Disulfiram requires high motivation and adherence, as it’s most effective when taken under supervision.

The Counseling Component

Medication alone is not MAT. The “treatment” in Medication-Assisted Treatment encompasses behavioral therapies and counseling that address the psychological, social, and behavioral dimensions of addiction:

• Cognitive Behavioral Therapy (CBT): Helps individuals identify and change negative thought patterns and behaviors that contribute to substance use
• Motivational Interviewing: A collaborative approach that strengthens motivation and commitment to change
• Contingency Management: Uses positive reinforcement to encourage healthy behaviors and abstinence
• Group Therapy: Provides peer support, social skill building, and shared accountability
• Family Therapy: Addresses relationship dynamics that may contribute to or be affected by substance use

The combination of medication and therapy is consistently more effective than either approach alone. Medication stabilizes the brain and body, creating a window of clarity in which therapeutic work can take place.

Who Is MAT For?

MAT is most commonly used for opioid use disorder and alcohol use disorder, where the evidence base is strongest. It may be appropriate for individuals who:

• Have tried abstinence-only approaches without success
• Have a moderate to severe substance use disorder
• Are at high risk of overdose or medical complications from withdrawal
• Want to reduce cravings that interfere with daily functioning
• Are pregnant and have an opioid use disorder (buprenorphine or methadone is recommended)

MAT is not a one-size-fits-all approach. The choice of medication, dosage, and duration should be individualized based on a thorough clinical assessment. Some individuals may use MAT for months; others may benefit from years of maintenance therapy. There is no clinically recommended maximum duration for MAT — the decision to taper should be made collaboratively between the patient and their provider.

Addressing Common Misconceptions

“MAT is just replacing one addiction with another.” This is the most harmful myth about MAT. Addiction is characterized by compulsive use despite negative consequences, loss of control, and craving. MAT medications, when taken as prescribed, do not produce a high, do not cause impairment, and allow individuals to function normally. They treat a medical condition, much like insulin treats diabetes.

“You’re not really sober if you’re on medication.” Recovery is about restoring function, health, and quality of life. Many people on MAT medications work, care for their families, and participate fully in their communities. Defining sobriety solely as the absence of all substances is a stigmatizing framework that discourages people from accessing life-saving treatment.

“MAT is a crutch.” If MAT is a crutch, then so are eyeglasses, blood pressure medication, and antidepressants. Substance use disorder is a chronic brain condition, and using medication to manage it is sound medical practice. The goal of treatment is to support recovery — not to prove one can suffer through it unaided.

Finding MAT Providers

Access to MAT has expanded significantly in recent years. You can find MAT providers through:

• SAMHSA’s Treatment Locator: findtreatment.gov allows you to search for providers offering MAT in your area
• SAMHSA’s National Helpline: Call 1-800-662-4357 for free referrals
• Your primary care physician: Many PCPs can now prescribe buprenorphine following the elimination of the X-waiver requirement in 2023
• Our directory: Use Get Matched to find facilities offering MAT in your state

The Bottom Line

Medication-Assisted Treatment saves lives. It is endorsed by the World Health Organization, the American Medical Association, the American Society of Addiction Medicine, SAMHSA, and virtually every major medical and public health organization. If you or someone you love is struggling with opioid or alcohol use disorder, MAT should be part of the conversation about treatment options.

Recovery is not about doing it the “hard way.” It’s about finding what works — and for millions of people, medication-assisted treatment is what works.

“Medication-Assisted Treatment is not the easy way out. It is the evidence-based way forward.”
