AI Summary Sustained alcohol abstinence is the cornerstone of treatment for alcohol-related liver disease, and AUD medicines can help people reach and keep it.
Medically reviewed.
Alcohol use disorder (AUD) pharmacotherapy is the use of prescription medicines to help people stop or cut back on drinking. These medicines can reduce cravings, lower the chance of relapse, or discourage drinking. They are used alongside counseling and support, and they help protect the liver by supporting lasting abstinence (not drinking alcohol).
This page explains the main AUD medicines, who may benefit, how liver health shapes the choice, and what follow-up involves. You can also connect with a liver specialist to discuss whether one of these medicines fits your care plan.

AUD PHARMACOTHERAPY OVERVIEW
AUD pharmacotherapy is a group of prescription medicines that support recovery from alcohol use disorder. Some reduce cravings. Some help steady the brain after long-term alcohol use. One discourages drinking by causing an unpleasant reaction if you drink. Care usually combines medicine with counseling, a structured recovery program, and regular follow-up. Your plan depends on your drinking history, your liver health, your kidney health, and your other medicines.
You can explore each medicine below and see how it works. Because the right choice depends on your health history, a liver specialist can help you understand which option fits your care plan.
Naltrexone blocks opioid receptors involved in the brain's alcohol reward pathways. This lowers the reward from drinking, eases cravings, and helps reduce heavy drinking. ReVia is a daily tablet. Vivitrol is a long-acting injection that a healthcare provider gives every 4 weeks. Naltrexone is generally avoided in advanced cirrhosis (Child-Pugh class C) and is not recommended in severe alcohol-related liver disease.

Acamprosate helps people who have already stopped drinking stay alcohol-free. It helps restore the balance of brain chemicals that long-term alcohol use disrupts, and it reduces cravings after withdrawal. It does not cause dependence. The liver does not break it down, so it is generally considered safe in liver disease. The kidneys clear it, so kidney function matters.

Baclofen is a muscle relaxant that doctors also use off label to reduce alcohol cravings and ease anxiety during recovery. Off label means the medicine is not officially approved for this use. The liver does not break it down in a major way, so it may be an option when liver disease limits other choices. Lioresal is a standard tablet. Kemstro dissolves on the tongue.
Explore baclofen therapies:
Disulfiram does not reduce cravings. It blocks the breakdown of alcohol, so drinking causes flushing, nausea, and a racing heartbeat. This reaction helps discourage drinking. It is meant for people who are committed to complete abstinence. It should be avoided in severe alcohol-related liver disease because it can harm the liver.
Explore this therapy:
Providers may consider AUD medicine for adults who are trying to reduce or stop drinking, have strong cravings, have finished alcohol withdrawal, and are taking part in a structured recovery program. People with alcohol-related liver disease are included, because stopping alcohol is the most important step for protecting the liver.
RECOVERY & LIFESTYLE SUPPORT
AUD medicine works best alongside counseling, a structured recovery program, and healthy daily habits. Medicine supports recovery, but it does not replace these steps.
Counseling or a support group helps you build coping skills. Medicine can make this work more effective. Regular follow-up with your addiction care provider keeps your plan on track.
Avoid alcohol completely while you take your medicine. With disulfiram, read labels carefully to avoid hidden alcohol, and do not drink for at least 14 days after you stop it.
A steady daily routine and a plan for situations that tempt you to drink lower the chance of relapse.
Limiting or stopping alcohol, keeping a healthy weight, and leading a healthy lifestyle all help protect your liver during recovery.
A nutrition bar designed for liver health can be a simple way to support your eating habits alongside treatment.

MEDICINE CHOICE AND LIVER HEALTH
AUD medicine should be evidence-based, safe for the liver, and part of a plan that includes counseling and behavioral support. Providers choose a medicine by how well it helps people stay abstinent or drink less, and by how the liver and kidneys handle it. They also check for interactions with other health conditions.
Liver disease changes which options are safest. The points below describe how each medicine fits. Your healthcare provider weighs them against your diagnosis and the stage of your liver disease.
With counseling, naltrexone can lower relapse rates and heavy drinking days compared with placebo. Severe liver disease can change how the body handles it, so it is generally avoided in Child-Pugh class C cirrhosis. Recent data suggest serious liver toxicity is rare.
In several trials, acamprosate improved abstinence compared with placebo. It is generally safe in liver disease, including Child-Pugh A and B cirrhosis, though data in Child-Pugh C are limited. Doses are reduced in kidney impairment, and acamprosate is avoided when kidney function is very low.
Baclofen has been studied in people with liver disease and may be a reasonable option for AUD in alcohol-related liver disease. It has reduced craving and drinking, including in some people with cirrhosis, but the evidence is mixed. Providers watch for sedation and muscle weakness.
Disulfiram should be avoided in severe alcohol-related liver disease because it can harm the liver. Providers reserve it for people who are committed to complete abstinence and who have a safe liver profile.
Gabapentin and topiramate are also used off label. Gabapentin has been studied for withdrawal symptoms and cravings and has minimal liver metabolism. Topiramate has reduced the share of heavy drinking days compared with placebo. Providers consider these when first-line medicines are not suitable or not tolerated.
TREATMENT MONITORING
Regular follow-up helps your healthcare provider see how you are responding to AUD medicine and catch problems early. Follow-up care may include blood tests, kidney checks, and visits with your addiction care team.
Liver function tests show how your liver is handling treatment. They are commonly recommended with naltrexone (ReVia, Vivitrol) and disulfiram (Antabuse).
Acamprosate (Campral) is cleared by the kidneys, so your provider may check kidney function, especially in older adults.
Baclofen can cause drowsiness, dizziness, and weakness. Regular visits let your provider adjust your treatment and review side effects.
Alcohol biomarker tests, such as urine ethyl glucuronide (EtG), can show recent drinking and help track your recovery.
Only a qualified healthcare provider can adjust your treatment plan based on your test results and health history.
COMMON QUESTIONS
AUD pharmacotherapy uses prescription medicines to help people with alcohol use disorder stop or reduce drinking and prevent relapse. The main options are naltrexone (ReVia, Vivitrol), acamprosate (Campral), baclofen (Lioresal, Kemstro), and disulfiram (Antabuse). These medicines work best with counseling and a structured recovery program. Talk with your healthcare provider about which one fits your treatment plan.
Stopping alcohol is the most important step for protecting your liver. Lasting abstinence improves survival, slows scarring, and can lead to partial or complete recovery of liver function, even in advanced disease. Many people cannot stop without help, so medicine and counseling can make a real difference. Without abstinence, no medical treatment can prevent further liver damage.
Each medicine works in a different way. Naltrexone blocks opioid receptors and lowers the reward from drinking. Acamprosate helps restore brain chemical balance and reduces cravings after withdrawal. Baclofen acts on GABA-B receptors to reduce cravings and ease anxiety. Disulfiram blocks the breakdown of alcohol, so drinking causes an unpleasant reaction. Your provider can explain how each one applies to you.
Acamprosate and baclofen are not broken down in the liver in a major way, so providers often consider them when liver disease limits other options. Naltrexone is generally avoided in Child-Pugh class C cirrhosis, and disulfiram should be avoided in severe alcohol-related liver disease. The right choice depends on your liver and kidney health, so your care team decides with you.
Providers may prescribe AUD medicine for adults who want to reduce or stop drinking, have strong cravings, and have finished alcohol withdrawal. Most people also take part in counseling or a structured recovery program. Eligibility depends on your drinking history, liver health, kidney health, and other medicines. Only a qualified healthcare provider can decide which option is right for you.
Side effects differ by medicine. Naltrexone can cause nausea, headache, dizziness, and fatigue. Acamprosate can cause diarrhea, nausea, abdominal discomfort, headache, and fatigue. Baclofen can cause drowsiness, dizziness, weakness, and headache. Disulfiram can cause drowsiness, headache, a metallic taste, and skin rash or itching. Your provider will monitor you and can help manage side effects.
No, you should avoid alcohol completely while taking an AUD medicine. With disulfiram (Antabuse), drinking causes an unpleasant reaction, and you should not drink for at least 14 days after you stop it. The other medicines also work best as part of full abstinence and recovery support. Ask your provider how to build a plan that pairs medicine with counseling.
