Naltrexone is a medication used to help manage alcohol and opioid dependence. It can be injected into muscle tissue or taken orally.
Brand names for Naltrexone include Vivitrol, the injectable, and Revia, the pill.
Naltrexone is an FDA-approved drug commonly used as part of medication-assisted treatment (MAT) programs for those with opioid or alcohol use disorders (AUDs).
The medication blocks the effects of opioids when someone takes them. However, researchers and medical professionals are less knowledgeable on exactly how Naltrexone treats alcoholism.
Naltrexone can’t cure addiction and should not be prescribed with that intent. Instead, doctors will prescribe it as part of a comprehensive treatment program. These treatment plans also include counseling and social support.
Naltrexone helps people with alcohol use disorder (AUD) stay sober. It’s also suitable for those who are dependent on narcotics.
Naltrexone may cause some side effects.
Speak with your doctor immediately if you experience any of the following:1
Some side effects of Naltrexone don’t usually require medical attention. These side effects may lessen during treatment as you adjust to the medicine. Additionally, your doctor may advise you on how to prevent or reduce side effects.
Speak with your doctor if any of the following side effects persist or are bothersome:
Other side effects not listed may also occur. If you notice any, speak with a healthcare professional.
Naltrexone causes severe liver disease in rare cases. This risk increases if you take larger doses. Be sure to discuss these risks with your doctor.

A serious allergic reaction to Naltrexone is rare.
Still, seek medical help immediately if you notice any symptoms of a severe allergic reaction, including:
Naltrexone may not interact well with certain medications. If you plan to take Naltrexone, let your doctor know if you’re taking any other medicines.
Some people fear that medication-assisted treatment causes one addiction to replace another. Methadone is an example of this.
Some people with opioid use disorder who start a methadone treatment program become addicted to the medication. The use of methadone and similar opioid treatments is carried out in a supervised manner. Yet, drug misuse and addiction are still possible.
Naltrexone isn’t addictive because it doesn’t cause people to feel high or euphoric. Instead, Naltrexone blocks the effects of alcohol or opioids to reduce cravings and relapse risk.
Becoming addicted to Naltrexone is unlikely. However, the risk of overdose is still possible.
Using opioids while taking Naltrexone can be a deadly combination. Naltrexone blocks the euphoric effects of opioid drugs. So if you take them on Naltrexone, you won’t experience any of these pleasurable effects.
As a result, some people try to increase the dose to experience the high they crave. This is what can lead to overdose or even death.
Often, if someone relapses, they’ll take the same dosage before becoming sober. This can also lead to overdose.
Most people with alcohol use disorder (AUD) benefit from professional treatment.
If you have an AUD and a mental disorder, it’s essential to seek treatment for both.
People with severe AUDs require intensive treatment. They will need to attend a residential treatment program, which is highly structured. It typically includes several types of behavioral therapies and detox medications for alcohol withdrawal.
Aside from Naltrexone, there are other medications to treat AUD.
The following are FDA-approved to treat AUD:2
Your doctor can help you determine whether Naltrexone or one of these other medicines is right for you. These medications aren’t addictive, so you don’t need to worry about transitioning from one addiction to another.
AUD medications are also not a cure for addiction. Rather, they can help manage withdrawal symptoms and reduce cravings.
Another term for behavioral therapies for AUD is alcohol counseling. This treatment involves working with healthcare professionals to pinpoint and change behaviors that contribute to alcoholism.
Some behavioral therapies include:2
CBT helps identify feelings and situations that result in heavy drinking. In CBT sessions, you learn coping skills, like managing stress and adjusting the thoughts that make you want to drink.
You may receive CBT one-on-one with a therapist or in small groups.
This treatment helps you build and strengthen the motivation to shift your drinking behavior. Motivational enhancement therapy typically includes four sessions over a short period.
Treatment begins with identifying the pros and cons of seeking treatment. Then, you and your therapist work on creating a plan to change your drinking habits.
The following sessions involve building your confidence and developing the skills you need to stick to the program.
This type of counseling includes partners and other family members in sessions. It repairs and enhances family relationships. Strong family support through therapy can help you avoid drinking.
These are short, one-on-one or small-group counseling sessions. This therapy includes one to four sessions.
The counselor provides you with information about your drinking behavior and potential risks. Then, they work with you to set goals and provide advice to help you change.
