What XIFAXAN 200 mg is used for:
XIFAXAN is an antibiotic that passes through the gastrointestinal tract and very little is absorbed. XIFAXAN 200 mg is used to treat travellers’ diarrhoea that is caused by bacteria that do not invade the gut wall, in people aged 12 years and older. XIFAXAN is not effective for diarrhoea caused by bacteria that invade the gut wall. There is no experience using XIFAXAN to treat travellers’ diarrhoea in children under 12 years of age. XIFAXAN may be prescribed for you before you travel overseas, so you have it with you if you need to treat an episode of diarrhoea.
Before you travel overseas, ask your doctor or pharmacist if you have any questions about why XIFAXAN has been prescribed for you, or how to use it. Your doctor may have recommended XIFAXAN tablets for another reason.
Before you take XIFAXAN 200 mg
When you must not take it
Do not take XIFAXAN tablets if:
- You have an allergy to rifaximin or any of the rifamycin antibiotics (rifampicin, rifabutin) or to any other ingredient contained in this medicine, listed at the end of this leaflet. Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itchiness or hives on the skin.
- You have bowel obstruction (a blocked bowel)
- You also have a fever, or blood in your stools. These are signs that the diarrhoea may be caused by an invasive bacteria that will not be effectively treated by XIFAXAN.
Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, see medical advice.
Before you start to take it
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you are pregnant or plan to become pregnant. Your doctor can discuss with you the risks and benefits involved.
Tell you doctor if you are breastfeeding. It is not known if your baby can absorb rifaximin from breast milk if you are breastfeeding.
If you have not told your doctor about any of the above, tell him/her before you start taking XIFAXAN tablets.
Taking other medicines
Tell you doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
There is a possibility that XIFAXAN can interact with other medicines, including ciclosporin, oral contraceptives and warfarin. Your doctor and pharmacist have more information on which medicines to be careful with or avoid while taking this medicine.

If you forget to take it
If it is nearly time for your next dose, skip the dose you missed and take the next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
If in Australia, immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to the Accident and Emergency department at the nearest hospital, if you think that you or anyone else may have taken too many XIFAXAN tablets.

While you are using XIFAXAN tablets
Things you must do
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you experience fever, if your diarrhoea becomes worse, you have blood in your stools, or if symptoms have not resolved after 3 days of treatment, then contact a doctor for assessment. Do not take a second course of XIFAXAN.
Things you must not do
Do not take XIFAXAN tablets to treat any other conditions unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor. If you stop taking it suddenly, your condition may worsen or you may have unwanted side effects.
Tell a doctor or pharmacist as soon as possible if you do not feel well while you are using XIFAXAN.
All medicines can have unwanted effects. Sometimes they are serious, most of the time they are not. Do not be alarmed by this list of possible side effects. You may not experience any of them.
Ask a doctor or pharmacist to answer any questions that you may have.
Tell your doctor or pharmacist if you notice any of the following common side effects and they worry you:
- dizziness, headache
- wind, abdominal bloating, abdominal pain, constipation, diarrhoea
- involuntary, painful, or ineffective straining on the toilet
- nausea, vomiting
The above list includes the more common side effects of your medicine reported in adults being treated for traveller’s diarrhoea. They are usually mild and short-lived.
Less common side effects include:
- Thrush, cold sore, swollen throat, inflammation or infection of the nose or throat
- Loss of appetite, dehydration
- Depressed mood, sleeplessness, nervousness
- Cough, dry or sore throat, runny nose, shortness of breath, blocked nose
- Muscle cramps, muscle pain, back or neck pain
- Chills, cold sweats, perspiration, flu-like illness
- Rash, blotchy skin, hot flushes.
Tell your doctor as soon as possible if you notice any of the following:
- Diarrhoea. XIFAXAN, like nearly all antibiotics, can alter the mix of bacteria in the intestine. This can lead to an overgrowth of a bacteria called Clostridium difficile (C. difficile). If you take XIFAXAN, there is a small risk that you could experience diarrhoea caused by C. difficile. If you develop severe diarrhoea after you have stopped XIFAXAN, contact your doctor immediately.
As with other medicines there is a small risk of serious allergic reactions. Consult your doctor immediately or go to the Accident & Emergency department of your nearest hospital if you notice any of the following:
- swelling of the face, lips or tongue which may make swallowing or breathing difficult
- asthma, wheezing, shortness of breath
- sudden or severe itching, skin rash, hives
Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
Other side effects not listed above may also occur in some people.
After using XIFAXAN tablets
Keep your tablets in the blister packaging until it is time to take them If you take the tablets out of the packaging they will not keep well.
Keep your tablets in a cool dry place where the temperature stays below 25°C.
Do not store XIFAXAN tablets or any other medicines in the bathroom or near a sink. Do not leave it on a window sill or in the car. Heat and dampness can destroy some medicines.
Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
If your doctor tells you stop taking this medicine or the expiry date has passed, ask your pharmacist what to do with any medicine that is left over.
