The most effective treatments for alcohol use disorder combine medication with behavioral therapy. Neither approach alone is a silver bullet, but together they significantly improve the odds of sustained recovery. Three FDA-approved medications and several well-studied therapy models form the backbone of modern treatment, and the best plan depends on whether your goal is complete abstinence or a reduction in heavy drinking.
FDA-Approved Medications
Three medications have FDA approval specifically for alcohol use disorder, and each works through a different mechanism. They’re roughly equal in overall effectiveness to behavioral therapy, and combining the two approaches tends to produce the best outcomes.
Naltrexone
Naltrexone blocks the brain’s opioid receptors, which are part of the reward system that makes drinking feel pleasurable. When those receptors are blocked, alcohol no longer produces the same dopamine surge, so the drive to keep drinking weakens. It’s available as a daily pill or a monthly injection. A large meta-analysis found that for every nine people treated with naltrexone, one additional person avoided a return to heavy drinking who otherwise would not have. That effect size is modest compared to some psychiatric medications, but it’s clinically meaningful as one piece of a larger treatment plan. Naltrexone works best for people whose primary goal is cutting back on heavy drinking rather than maintaining total abstinence, and studies show it’s more effective when patients have a period of abstinence before starting the medication.
Acamprosate
Acamprosate targets a different problem entirely. Chronic heavy drinking disrupts the balance between excitatory and calming signals in the brain, leaving the nervous system in a hyperexcited state after you stop. Acamprosate helps restore that balance by regulating activity at key receptor sites involved in excitatory signaling. This calming effect reduces the distress and cravings that come with early sobriety. A meta-analysis of 24 clinical trials found that acamprosate reduced the risk of returning to any drinking by 86% compared to placebo during treatment and increased the total duration of abstinence by about 11%. After stopping the medication, people who had taken acamprosate still had a 9% lower risk of relapse. It’s taken three times daily and works best for people committed to complete abstinence rather than moderation.
Disulfiram
Disulfiram is the oldest of the three and works through a completely different strategy: deterrence. It blocks an enzyme your body needs to process alcohol, so if you drink while taking it, a toxic byproduct called acetaldehyde builds up rapidly. The result is intense flushing, nausea, vomiting, rapid heartbeat, and a dangerous drop in blood pressure. The reaction is unpleasant enough that the fear of it keeps many people from drinking. The catch is compliance. In one study, about 64% of patients took their medication reliably and kept their appointments, while roughly 16% were inconsistent with either the medication or their visits. Disulfiram works well for highly motivated patients, especially when a family member or clinician supervises each dose, but it’s less effective when someone simply has a bottle on their nightstand and stops taking it before a planned relapse.
Second-Line Options
For people who don’t respond to these three medications or prefer alternatives, the American Psychiatric Association suggests two additional options. These are used off-label but have growing evidence behind them. One reduces cravings by calming overactive nerve signaling, and the other appears to help normalize brain chemistry disrupted by heavy drinking. Your prescriber can discuss whether either is a good fit based on your history and other medications.
Behavioral Therapies That Work
Medication addresses the biology of alcohol dependence, but behavioral therapy tackles the patterns of thinking, emotional triggers, and social situations that drive relapse. Several approaches have strong evidence.
Cognitive behavioral therapy (CBT) teaches you to identify the specific thoughts and situations that lead to drinking, then develop concrete coping strategies. A typical course runs about eight weeks. One challenge is that CBT requires consistent engagement. In a recent randomized trial, only 50% of participants assigned to CBT completed at least five sessions, which underscores the importance of finding a format that fits your life, whether in-person, digital, or group-based.
Motivational enhancement therapy (MET) takes a different approach. Instead of teaching skills directly, it helps you work through your own ambivalence about changing. Sessions explore the pros and cons of drinking, clarify your personal values, and build your confidence that change is possible. A typical course involves around 10 sessions and includes exercises in craving management, distraction techniques, and decisional balance. Studies show MET significantly improves self-efficacy, meaning your belief in your own ability to refuse a drink, compared to standard treatment alone.
Relapse prevention therapy, contingency management programs, and 12-step facilitation therapy round out the evidence-based options. The common thread across all of them is that they work best when you actually attend. Showing up consistently matters more than which specific approach you choose.
Medical Detoxification as a Starting Point
For people who are physically dependent on alcohol, treatment has to start with safely managing withdrawal. Alcohol withdrawal can range from mild anxiety and tremors to life-threatening seizures and a condition called delirium tremens. This is one area where medical supervision isn’t optional for heavy, long-term drinkers.
Benzodiazepines are the gold standard for managing withdrawal symptoms. They reduce the risk of seizures and severe complications. Longer-acting options are generally preferred, though shorter-acting alternatives are used when someone has liver disease or other health conditions. The typical protocol involves stabilizing symptoms over two to three days, then gradually tapering the medication over seven to 10 days. Minor withdrawal, on the other hand, may only need supportive care in a calm environment with observation for up to 36 hours.
Detox by itself is not treatment for alcohol use disorder. It’s the necessary first step that makes longer-term therapy and medication possible. Skipping the transition from detox into ongoing care is one of the most common points where people fall out of recovery.
Mutual Support Groups
Support groups aren’t formal treatment, but they play a significant role in long-term recovery. The two most widely available options are Alcoholics Anonymous (AA) and SMART Recovery, and they differ in philosophy and structure.
AA follows a 12-step program grounded in spiritual principles. Meetings are led by members in recovery, and the organization strongly encourages new members to find a sponsor, an experienced member with at least a year of sobriety who serves as a mentor and is available between meetings. Research points to three factors that have the biggest positive effect on recovery through AA: having a sponsor (the single most important factor), attending at least three meetings per week especially in the first year, and speaking aloud during meetings, even briefly.
SMART Recovery takes a secular, science-based approach. It incorporates cognitive behavioral techniques and motivational psychology into group sessions led by trained facilitators who don’t need to be in recovery themselves. SMART doesn’t use formal sponsors, though members are encouraged to exchange contact information and support each other between meetings. People who gravitate toward SMART tend to have less severe alcohol problems, higher education levels, and less prior treatment history compared to those who choose AA.
Neither approach is universally better. The best group is the one you’ll actually attend, and many people try both before settling on what fits.
Combining Treatments for Better Outcomes
The strongest evidence supports combining medication with behavioral therapy rather than relying on either alone. In one well-designed study, acamprosate paired with behavioral therapy produced a 47.6% success rate at the end of treatment and 35% at six-month follow-up. Interestingly, placebo paired with the same behavioral therapy produced nearly identical results (48% and 32%), which highlights how powerful therapy itself is, while the medication added a durable edge over time.
The NIAAA recommends that clinicians tailor combinations to each patient. Someone whose main struggle is intense cravings during early sobriety might benefit most from acamprosate plus CBT. Someone who drinks heavily on weekends but can stay dry during the workweek might respond better to naltrexone plus motivational enhancement therapy. A person who has relapsed multiple times might do well with supervised disulfiram plus frequent AA attendance.
Recovery is not a single event but an ongoing process, and the treatments that work best are the ones that address your specific biology, your psychological triggers, and the social environment you live in. Most people need to try more than one approach, adjust their plan over time, and stay engaged with some form of support for at least a year to see lasting results.
