Naltrexone for Alcohol Issues

Naltrexone for alcohol issues:

how It works, expectations & options

Naltrexone is a first-line, evidence-based medication used in the treatment of alcohol dependence in Australia.

It has been extensively studied and is considered safe and effective when used under medical supervision.

What we do

How naltrexone works

Naltrexone blocks opioid receptors in the brain.

This reduces:

the rewarding or euphoric effects of alcohol
reinforcement of drinking behaviour.

Over time, this can lead to reduced cravings and lower alcohol consumption.

Who We Help

What naltrexone does - and doesn’t do

Naltrexone can:

reduce heavy drinking
support behavioural change
lower relapse risk.

Naltrexone does not:

prevent you from becoming intoxicated
reduce blood alcohol concentration
eliminate withdrawal symptoms.

People who are physically dependent may still require supervised detox.

New Possibilities

Is naltrexone right for you?

Naltrexone is not the only option, nor the only medication our program supports.

Other evidence-based medications including Acamprosate (Campral) and Dilsulfiram (Antabuse) are available and can be prescribed by your GP.

Importantly:

medication is only one part of treatment
psychological support plays a key role
treatment should be tailored to the individual
