How Medication-Assisted Treatment Works for Alcohol and Opioid Recovery

If you have been trying to get clean from opioids or alcohol and keep ending up back where you started, you are not alone and you are not out of options. Medication-assisted treatment, or MAT, is one of the most effective evidence-based approaches we have for both alcohol and opioid use disorders. It combines FDA-approved medications with counseling and behavioral therapy. In Georgia, access to a comprehensive medication-assisted treatment in Georgia program can mean the difference between another relapse and a recovery that actually holds. The concept is straightforward but widely misunderstood.

MAT is not replacing one addiction with another. It is not a crutch or a shortcut. The medications normalize brain chemistry, block the euphoric effects of alcohol or opioids, and reduce physiological cravings so the person can actually engage with therapy and rebuild their life. Without the medication, the cravings and withdrawal symptoms are often overwhelming enough that willpower alone is not enough. Understanding how these medications work and what they actually do in the body is the first step toward seeing MAT for what it really is: a legitimate medical intervention with decades of research behind it.

How MAT Works for Opioid Addiction

Opioids bind to specific receptors in the brain called mu-opioid receptors. They produce pain relief and a rush of dopamine that reinforces continued use. Over time, the brain stops producing its own natural opioids and becomes dependent on the external source. When the drug leaves the system, withdrawal sets in with symptoms that can include severe muscle aches, diarrhea, vomiting, anxiety, and an overwhelming craving for more opioids. That is where MAT comes in.

Three FDA-approved medications are used for opioid use disorder, and each works differently.

Buprenorphine is a partial opioid agonist. It activates the same mu-opioid receptors as heroin or prescription painkillers but to a much weaker degree, and critically, the effect plateaus at higher doses. This ceiling effect makes buprenorphine significantly safer in overdose situations compared to full agonists. It reduces cravings and prevents withdrawal without producing the same high. Because of its safety profile, buprenorphine can be prescribed in a doctor’s office rather than requiring daily clinic visits, which makes it far more accessible than methadone for many people. It is available as a sublingual tablet or a long-acting injection.

Methadone is a full opioid agonist. It activates the opioid receptors fully, which makes it highly effective at preventing withdrawal and blocking cravings. But because it carries a risk of misuse and respiratory depression, it must be dispensed daily through federally regulated opioid treatment programs. Methadone has been used for decades with an excellent track record when taken as prescribed. The World Health Organization lists it on its Model List of Essential Medicines, and it remains one of the most studied treatments for opioid addiction in existence.

Naltrexone works completely differently from the first two. It is an opioid antagonist, meaning it blocks the opioid receptors entirely. If a person on naltrexone uses heroin or fentanyl, the drug cannot bind to the receptors and produces no effect at all. This makes naltrexone particularly valuable for people who have already detoxed and want a pharmacological safeguard against relapse. Naltrexone does not prevent withdrawal the way buprenorphine or methadone do, so the person must be fully detoxed before starting it. It is available as a daily pill or a once-monthly injection. The injectable form, Vivitrol, is often preferred because it removes the daily decision to take medication — one shot and the protection lasts for 30 days.

Each of these medications is more effective when combined with counseling and behavioral therapy. A study in the Journal of the American Medical Association found that buprenorphine maintenance therapy reduced opioid use by 40 to 70 percent compared to placebo. Another study showed that MAT for opioid addiction decreased emergency room visits by 51 percent. The data is consistent across multiple large-scale reviews: people on MAT are significantly more likely to stay in treatment, less likely to relapse, and less likely to overdose than people who attempt recovery without medication.

How MAT Works for Alcohol Addiction

Alcohol use disorder affects an estimated 14.5 million people in the United States. It is the third-leading preventable cause of death. Yet the vast majority of people with AUD never receive any medication to treat it, despite the fact that the National Institute on Alcohol Abuse and Alcoholism has endorsed MAT for alcohol for years. MAT for alcohol is just as evidence-based as it is for opioids, and it is similarly underused.

Three medications are FDA-approved for alcohol use disorder.

Naltrexone also works for alcohol, but through a different mechanism than it does for opioids. When a person drinks alcohol, the body releases endorphins that produce a sense of pleasure and reward. Naltrexone blocks those endorphins from binding to receptors in the brain. The person still feels the effects of alcohol — they will still get drunk — but they do not get the rewarding buzz that drives continued drinking. Over time, the brain stops associating alcohol with pleasure, and drinking loses its pull. Naltrexone has been shown to reduce heavy drinking days by 17 percent and lower the risk of relapse by 36 percent. It is available as a daily oral tablet or a once-monthly injection.

Acamprosate works on the glutamate system in the brain to restore the chemical balance disrupted by chronic alcohol use. Prolonged drinking throws several neurotransmitter systems out of equilibrium, and acamprosate helps bring them back into balance. It reduces cravings and helps with the anxiety and insomnia that often accompany early recovery. One study found that acamprosate improved the chances of staying completely abstinent after detox by about 15 percent. It is taken as a tablet three times a day and works best for people who have already stopped drinking and are committed to maintaining abstinence.

Disulfiram is the oldest of the three and works as a behavioral deterrent rather than a craving reducer. It inhibits an enzyme called aldehyde dehydrogenase, which is involved in alcohol metabolism. If a person taking disulfiram drinks even a small amount of alcohol, acetaldehyde builds up in the blood and causes flushing, nausea, vomiting, headache, chest pain, and difficulty breathing within minutes. The reaction is unpleasant enough that most people simply choose not to drink while on it. Disulfiram requires commitment — you have to take it every day knowing the consequences of slipping. For people who are motivated and have a support system in place, it can be highly effective.

The Combination That Makes MAT Work

Medication alone is not enough, and that point is worth emphasizing. MAT is called medication-assisted treatment for a reason. The medication is the assist, not the whole game.

The comprehensive approach includes individual counseling to identify triggers and develop coping strategies, group therapy to build peer support and accountability, and medical monitoring to adjust medications and manage side effects. At The Recovery Village Atlanta, MAT is integrated into a full continuum of care that includes detox, residential treatment, partial hospitalization, and intensive outpatient programs. The goal is not just to stabilize the person on medication but to build the skills and support network they need to eventually maintain recovery without it, if that is the right goal for them.

Some people stay on MAT for months. Some stay for years. Some remain on it indefinitely, and that is fine. The National Institute on Drug Abuse has stated clearly that discontinuing MAT increases the risk of relapse and overdose. There is no arbitrary timeline for when someone should stop. The decision is made collaboratively between the patient and their treatment team based on stability, personal goals, and risk factors.

Addressing the Stigma

One of the biggest barriers to MAT is not medical. It is cultural. There is a persistent belief in some recovery circles that using medication to treat addiction is not real sobriety. Some 12-step groups have discouraged members from taking MAT, and that stigma has seeped into the broader culture. This misconception keeps people from seeking treatment and has contributed to tragically low MAT adoption rates across the country.

The data does not support the stigma. MAT reduces overdose deaths. It improves treatment retention. It lowers the risk of infectious disease transmission. The American Medical Association, the World Health Organization, and the Substance Abuse and Mental Health Services Administration all endorse MAT as a standard of care. Calling medication-assisted treatment a crutch makes about as much sense as calling insulin a crutch for diabetes. The medication does not do the work for you. It makes the work possible.

Getting Started with MAT

Starting MAT involves a medical evaluation to determine which medication is appropriate based on the substance used, medical history, and personal treatment goals. For opioids, the process often begins with medically supervised detox before transitioning to a maintenance medication like buprenorphine or methadone, or to naltrexone for relapse prevention after detox. For alcohol, some medications like naltrexone can be started while the person is still drinking, while others like acamprosate and disulfiram require a period of abstinence first.

The Recovery Village Atlanta offers confidential assessments and can help verify insurance coverage before any commitment. Their MAT program is physician-led and integrated with the full range of behavioral therapies available at their Roswell and Stockbridge facilities. The admissions team is available 24/7 to answer questions about what to expect and how to get started.

The most important step is the first one. If you have been struggling with alcohol or opioid addiction and wondering whether medication could help, the answer is probably yes. Talk to a provider who understands MAT. Ask the questions you need to ask. Do not let stigma — yours or anyone else’s — stand between you and a treatment that works.
