Rifaximine pour la diarrhée du voyageur

About rifaximin

Diarrhée du voyageur is diarrhoea that develops during, or shortly after, you have travelled abroad. Diarrhoea is defined as 'loose or watery stools, usually at least three times in 24 hours'. Traveller's diarrhoea is commonly caused by eating food or drinking water containing germs (bacteria). In most cases, the symptoms are mild, and the body's immune system clears them within a few days.

Rifaximin is an antibiotic which works within the gastrointestinal system. It is not absorbed into the body (this means that it is not suitable to treat other types of infection). You may be advised by your doctor to take a supply with you when you travel, 'just in case' you develop diarrhoea. You will be prescribed a brand called Xifaxanta®. The tablets are not suitable if you also have a high temperature (fever) or if there is blood in the diarrhoea - you should get medical assistance as soon as possible in these cases. Rifaximin should not be given to children.

(A brand of rifaximin tablets called Targaxan® is used to help prevent episodes of a problem called hepatic encephalitis in people with liver disease. If you are taking it for this reason, see the separate leaflet called Rifaximine pour les problèmes hépatiques.)

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 rifaximin it is important that your doctor knows:

• Si vous êtes enceinte, essayez d'avoir un bébé, ou allaitez.

• If you have any problems with your kidneys.

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

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.

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

• Take rifaximin exactly as your doctor tells you to. Take one 200 mg tablet every eight hours for three days (Xifaxanta® brand). It is important that you space the doses out evenly, and that you remember to finish the whole course of tablets. Swallow the tablets with a drink of water; they can be taken with or without food.

• If you forget to take a dose, take it as soon as you remember. Try to take the correct number of doses each day, spaced out evenly. Do not take two doses together to make up for a missed one.

• It is important for you to drink plenty of fluids to avoid dehydration. You can drink 'safe' water (for example, bottled, or boiled and treated water) or rehydration drinks (which contain a balance of salts and sugars and can be bought from a pharmacy before you travel). Remember to make up rehydration drinks using safe water.

• Eat as soon as you feel able to. Plain foods such as bread and rice are good foods to eat. Try to avoid fatty, spicy or heavy food.

• Taking rifaximin could cause a slight reddish colour in your urine. This is normal and harmless.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with rifaximin when taken for traveller's diarrhoea. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to the tablets, speak with a doctor or pharmacist for further advice.

• Gardez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.
