What is Naltrexone?

Naltrexone is a medication that was approved by the FDA in 1984. It is a potent opioid receptor antagonist. That means that it works by binding to opioid receptors and blocking the effects of opioids. It is used to treat alcohol and drug dependence. It is available in oral and injectable forms.

What are the benefits of drinking on Naltrexone?

When used as prescribed, naltrexone can provide many benefits. It can help to:
-Reduce cravings for alcohol
-Decrease the amount of alcohol consumed
-Make it easier to stick to treatment goals

Naltrexone can also help to reduce other risky behaviors, such as:
-Unsafe sex
-Driving while intoxicated
-Drinking while pregnant

In some cases, naltrexone may also be used to treat other conditions, such as:
-Opioid addiction


Drinking on naltrexone can cause serious side effects and should be avoided. Some of the risks associated with drinking on naltrexone include liver damage, gastrointestinal problems, and seizures. If you are pregnant or breastfeeding, you should also avoid drinking on naltrexone as it can harm the developing fetus or infant.

Liver damage

Naltrexone is a medication that blocks the effects of drugs known as opiates. It is used to treat addiction to alcohol or drugs. Naltrexone is not a narcotic and it will not produce intoxication. It should not be confused with naloxone, which is a medication used to treat narcotic overdoses.

Naltrexone can cause liver damage. Symptoms of liver damage include yellowing of the skin or eyes, dark urine, pain in the upper right side of the abdomen, and fatigue. If you experience any of these symptoms, you should stop taking naltrexone and see your doctor immediately.

Increased risk of overdose

If you drink alcohol while taking naltrexone, you’re at risk of overdose. If you take naltrexone and then drink, you may feel nauseous, vomit, have abdominal pain, and experience dizziness, drowsiness, or “out-of-body” sensations. You may also have trouble breathing. If you have these symptoms, call 911 or go to the nearest emergency room immediately.

Worsening of mental health symptoms

It’s important that you’re aware of the risks associated with drinking alcohol while taking naltrexone. One of the most serious risks is that your mental health symptoms may worsen. If you’re already struggling with depression, anxiety, or any other mental health condition, drinking alcohol while taking naltrexone can make your symptoms worse. In some cases, people have even experienced suicidal thoughts or attempts when they drink alcohol while taking naltrexone. If you’re struggling with mental health symptoms, it’s important to talk to your doctor about whether naltrexone is right for you.

This can help to reduce cravings and prevent relapse. However, drinking alcohol while taking naltrexone can cause some unpleasant side effects


Acamprosate is a medication that is used to treat alcohol dependence. It is thought to work by reducing cravings for alcohol.

Acamprosate is usually taken three times a day. Common side effects include diarrhea, nausea, and headache.

Acamprosate should not be taken if you are pregnant or breastfeeding. It may also not be suitable for people with kidney disease.

If you are considering taking acamprosate, please speak to your doctor or healthcare provider first.


Disulfiram is an alcohol-sensitizing drug that is sometimes used as an alternative to naltrexone. It works by causing negative physical reactions when alcohol is consumed, making it less pleasurable to drink. Disulfiram can cause nausea, vomiting, headaches, and fatigue when alcohol is consumed, and in some cases can lead to hypotension (low blood pressure) and tachycardia (rapid heartbeat). It is important to note that disulfiram should never be taken without medical supervision, as it can be dangerous if not used properly.


Nalmefene, sold under the brand names Selincro and ReViao, is a medication developed by Orexo for the reduction of alcohol consumption. It is a μ-opioid receptor antagonist (MORA) and was approved for medical use in Europe in 2013.

Nalmefene is intended to be used as an adjunct to psychological support in the treatment of alcohol dependence in adults who have, over the previous 6 months, been drinking excessively despite harmful consequences or a desire to cut down. A 2015 review found that when compared to placebo, nalmefene reduces alcohol consumption without inducing withdrawal symptoms or other adverse effects.

There is some evidence that nalmefene may be more effective than naltrexone in reducing alcohol consumption; however, the two drugs have similar efficacy overall.
