Lofexidine is a treatment for opioid drug dependence. Medicines for drug dependence are mainly used to reduce or prevent withdrawal symptoms while trying to break drug use.

Lofexidine is usually used alongside, but sometimes instead of, other medicines taken for opioid drug dependence such as methadone or buprenorphine. It helps to reduce withdrawal effects such as chills, sweating, stomach cramps, muscle pain, difficulties sleeping and runny nose.

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

  • Om du är gravid eller ammar.

  • If you have a heart condition, or if you have had a heart attack, or if you have a heart rhythm problem such as a slow or irregular heartbeat.

  • Om du har lågt blodtryck.

  • If you have had a stroke or 'mini-stroke' (also known as a transient ischaemic attack, or TIA).

  • If you are feeling depressed.

  • Om du har några problem med hur dina njurar fungerar.

  • Om du tar eller använder några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

  • Om du någonsin har haft en allergisk reaktion mot en medicin.

  • Lofexidine is used as part of a detoxification programme. Because each programme is tailored to meet a person's individual needs and no two detoxifications are exactly the same, it is important that you take lofexidine exactly as your doctor tells you to.

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

  • Your doctor or community drug-team worker will tell you when and how often to take the tablets. It is likely that you will be asked to take four tablets over the course of the first day. Take your last dose of the day at bedtime, as this will help to reduce any problems you may have sleeping. Your dose may then be increased over the next few days. The maximum number of tablets you will be prescribed to take at any one time is 4, and the maximum number of tablets during any one day is 12.

  • You can take lofexidine tablets either before or after meals. Swallow the tablets whole with a drink of water.

  • If you forget to take a dose, take it as soon as you remember and then continue as before. Do not take two doses together to make up for a missed dose.

  • It is usual to take lofexidine for around 7-10 days, although sometimes a course of treatment can be for longer than this. You should not stop taking lofexidine suddenly, as this can cause your blood pressure to rise quickly which could be harmful. At the end of the treatment, your doctor will ask you to reduce your dose gradually over a few days to prevent this from happening.

  • It is important that you keep your regular appointments with your doctor/clinic so that your progress can be reviewed. Your blood pressure and pulse rate will need to be regularly monitored (especially in the first few days) to make sure you are taking a dose which helps your condition but avoids unwanted symptoms.

  • Lofexidine will help you to deal with withdrawal symptoms but it will not help you through cravings. You are more likely to succeed in breaking your drug habit if you have support and counselling. Local drug community teams, self-help groups and other agencies can be of help. It is much harder to 'do it alone', so go for counselling and help if it is available in your area. Try to stay positive and relaxed, drink plenty of fluids, and eat a light diet.

  • You should not drink alcohol while you are on lofexidine because it can increase side-effects such as feeling sleepy or dizzy.
