About naltrexone

Type de médicament

An opioid antagonist

Utilisé pour

To help prevent relapse in people with previous opioid or alcohol dependence

Tablettes

You will have been prescribed naltrexone if you have been through an opiate or alcohol detoxification regime and you are committed to remaining drug/alcohol-free. Alongside other forms of treatment and abstinence support, taking naltrexone can help you to remain free from your dependence.

Naltrexone acts by blocking opioid receptors in your brain and nervous system. This means that you will no longer experience the euphoria-like effects that you previously experienced from substance use. Knowing this will help to support your decisions to stay drug/alcohol-free.

Your treatment with naltrexone will be started and supervised by an appropriate specialist.

Before taking naltrexone

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking naltrexone it is important that your doctor knows:

  • If you have taken any opiate drug in the previous 10 days. This includes any cough medicines or painkillers that contain opiates.

  • Si vous avez des problèmes de fonctionnement du foie ou des reins.

  • Si vous êtes enceinte ou si vous allaitez.

  • Si vous prenez ou utilisez d'autres médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

  • Si vous avez déjà eu une réaction allergique à un médicament.

How to take naltrexone

  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about naltrexone and will provide you with a full list of the side-effects which you may experience from taking it.

  • Take naltrexone exactly as your doctor tells you to. Your dose will be printed on the label of the pack to remind you about what was said to you.

  • When starting the treatment, your doctor will give you a small dose of 25 mg a day (half a tablet) and then will increase the dose to one 50 mg tablet a day. The usual maintenance dose is 50 mg (one tablet) each day, although your doctor may suggest that you take naltrexone on three days of the week only (such as two tablets on Mondays and Wednesdays and three tablets on Fridays).

  • Try to take your doses at the same time of day each day, as this will help you to remember to take the tablets regularly. Swallow the tablet with a drink of water. It can be taken either before or after a meal.

  • If you forget to take a dose at your usual time, take it when you remember. If you do not remember until the following day, leave out the forgotten dose but make sure that you remember to take that day's dose. Do not take two doses together to make up for a forgotten dose.

Tirer le meilleur parti de votre traitement

  • Keep your regular appointments with your doctor and programme supervisor. This is so that your progress can be checked. Before you are prescribed naltrexone, your doctor is likely to test you to make sure that you are free from opiates. Also, your doctor will want to take a blood sample from you both before and during your treatment with naltrexone to check that your liver is working well.

  • Keep taking the tablets until your doctor tells you otherwise. You may need to continue to take naltrexone for a number of months, although your doctor will review this regularly.

  • If you are having any medical treatment, you must tell the person carrying out the treatment that you are taking naltrexone. This is particularly important to ensure that you get proper pain treatment in case of an emergency.

  • If you buy any medicines 'over the counter', always check with a pharmacist that they are suitable for you to take with naltrexone. Some medicines for cold and flu symptoms contain weak opioids, as do some medicines for diarrhoea - you must not take these.

  • These tablets are for you - do not give them to anyone else, even if their condition appears to be the same as yours. If they are taken by anyone who is dependent on opioids, they could cause serious life-threatening withdrawal symptoms.
