Naltrexone is recommended as a treatment option for people who have been opioid dependent but who have stopped using opioids, and who are highly motivated to stay free from the drugs in an abstinence programme.
It should only be given to people who have been told about the problems associated with treatment, and with proper supervision. Treatment with naltrexone should be given as part of a support programme to help the person manage their opioid dependence.
Healthcare professionals should regularly review how well naltrexone is working to help people stay off opioids. If there is evidence that the person has been using the drugs again then healthcare professionals should consider stopping naltrexone treatment.
