What should you know about rifaximin travellers diarrhoea?

Travellers’ diarrhoea can follow contaminated food or water and may include loose stools, cramps, nausea or fever. Rifaximin acts mainly inside the gut, but it is not suitable for every pattern of illness. It may not address invasive infection, blood in the stool, or diarrhoea from a parasite, virus, intolerance or an ongoing bowel condition. Other explanations include Food Poisoning, Gastroenteritis and Giardiasis.

Prioritise frequent sips of safe fluids and consider an oral rehydration solution if fluid loss is significant. Take rifaximin only as prescribed and complete the instructed course unless a clinician tells you to stop. Tell the prescriber about allergies, pregnancy, liver problems and other medicines. Avoid sharing antibiotics. Persistent or recurrent symptoms may need assessment for Coeliac Disease, Crohn's Disease, Food Intolerance, Hyperthyroidism or Irritable Bowel Syndrome.

Seek prompt medical care for blood or black stool, high fever, severe abdominal pain, repeated vomiting, confusion, fainting, very little urine or signs of dehydration. Contact a clinician if symptoms are not improving, return after treatment, or affect a young child, older adult or person with significant illness. Do not delay care because an antibiotic has been prescribed.

Ask whether your symptoms fit bacterial travellers’ diarrhoea, how to take the medicine, what improvement to expect, and which warning signs require urgent review. Clarify whether you need testing or advice about returning to food preparation, work or travel.
