Clinical author's note Michael Stewart 19/03/2019: Diloxanide tablets were discontinued in the UK in June 2018. At the time of review there are no branded or generic products containing diloxanide available in the UK. Diloxanide may still be available in other countries. This medicine leaflet is based on medical information available in the UK at the time of writing and is left here for reference purposes. Please also refer to the manufacturer's information supplied with your medicine.
Diloxanide is used to treat an infection in your bowel.
Take one tablet every eight hours for 10 days.
If you have diarrhoea, drink plenty of fluids so that you don't become lacking in fluid in the body (dehydrated).
Even if you don't feel unwell, it is important that you complete the full course of tablets.

About diloxanide
Typ av medicin | An amoebicide |
Används för | Amoebiasis (in adults and in children over 12 years of age) |
Även kallad | Diloxanide furoate |
Tillgänglig som | Tablets (discontinued), oral liquid medicine (special order) |
Diloxanide is used to treat an infection caused by a very small living organism (amoeba) called Entamoeba histolytica (often shortened to E. histolytica).
Infection with the amoeba can occur after drinking water contaminated by infected stools (faeces) or eating food prepared or washed using contaminated water. Most people with amoebiasis do not develop any symptoms, but in those who do, diarrhoea is the most common symptom. People most at risk of amoebiasis include travellers to areas where infection with the amoeba is common, such as countries with poor sanitation.
Treatment for amoebiasis includes medication such as diloxanide to kill the organism, and drinking plenty of fluids to prevent lack of fluid in the body (dehydration).
Before taking diloxanide
Tillbaka till innehållSome 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 diloxanide it is important that your doctor knows:
Om du är gravid eller ammar.
If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take diloxanide
Tillbaka till innehållBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about diloxanide, and will also provide you with a full list of the side-effects which you could experience from taking it.
Take the tablets exactly as your doctor tells you to. It is usual to take one tablet three times a day for 10 days. Space your doses out evenly throughout the day - so ideally, take one tablet every eight hours. You can take the tablets either with or without food.
Even if you feel well, keep taking the tablets until the course is finished (unless your doctor tells you to stop). If you forget to take a dose, take it as soon as you remember. Try to take the correct number of doses each day but do not take two doses at the same time to make up for a missed dose.
Få ut det mesta av din behandling
Tillbaka till innehållIt is very important when you have diarrhoea that you drink plenty of fluids to prevent you from becoming lacking in fluid in the body (dehydrated). Your doctor will advise you about how much and what type of fluids you should drink.
Wash your hands thoroughly after going to the toilet. This will help to prevent the spread of the infection to others. Ideally, use liquid soap in warm running water, but any soap is better than none. Dry your hands properly after washing, and don't share towels or flannels with other people.
Regularly clean the toilets that you use with disinfectant. Keep a cloth just for cleaning the toilet (or use a disposable one each time). Remember to wipe the flush handle, toilet seat, bathroom taps and door handles at least once a day with hot water and detergent.
Be careful to wash your hands before preparing, serving, or eating your food. Don't prepare or serve food for others.
You should stay off work, school, college, etc, while you have amoebiasis. Your doctor will advise you when it is suitable for you to return. Avoid contact with other people as far as possible during this time.

Vanliga frågor
How does diloxanide work to treat amoebiasis?
Diloxanide is an amoebicide, which means it is a type of medicine specifically designed to kill the tiny living organism, Entamoeba histolytica, that causes amoebiasis. By targeting and eliminating this organism, diloxanide helps to clear the infection from the body.
Can I get amoebiasis from sources other than contaminated water or food?
The article states that infection with the amoeba can occur after drinking water contaminated by infected stools (faeces) or eating food prepared or washed using contaminated water. It does not mention other methods of transmission.
What should I do if I forget to take a dose of diloxanide?
If you forget a dose, take it as soon as you remember. You should try to take the correct number of doses each day, but importantly, do not take two doses at the same time to compensate for a missed dose.
Should I continue taking diloxanide if I start to feel better before the course is finished?
Yes, it is important to keep taking the tablets until the entire course is finished, even if you start to feel well. This ensures the infection is fully treated, unless your doctor specifically tells you to stop.
What precautions should I take to prevent spreading amoebiasis to others while I'm infected?
To prevent spreading the infection, you should wash your hands thoroughly after using the toilet, clean toilets regularly with disinfectant, wash hands before handling food, and avoid preparing or serving food for others. It's also advisable to stay off work, school, or college and limit contact with other people until your doctor advises it's safe to return.
What kind of symptoms should prompt me to contact my doctor regarding diloxanide side effects?
While some common side effects like feeling sick, loss of appetite, diarrhoea, tummy cramps, or wind often improve as your body adjusts, you should speak with your doctor or pharmacist if these continue or become troublesome. Additionally, if you experience a skin rash, itching, headache, or dizziness and they become bothersome, or if you notice any other symptoms you think might be due to the tablets, you should seek their advice.
Can children under 12 years old take diloxanide?
Diloxanide is used for amoebiasis in adults and in children over 12 years of age. This suggests it is not typically prescribed for children under this age.
