What are the treatment recommendations for severe travelers diarrhea?

In serious cases of travelers' diarrhea, oral rehydration solution—available online or in pharmacies in developing countries—can be used for fluid replacements. Several drugs, such as loperamide, can be bought over-the-counter to treat the symptoms of diarrhea.

Patients with moderate illness may be treated with antibiotics, with or without adjunctive loperamide. Timely and effective self-treatment with antibiotics in moderate TD reduces the duration of illness to approximately 36 hours, with further reduction to less than 12 hours from combination therapy with loperamide.

Travellers' diarrhoea tends to happen in the first week of travel. Symptoms last on average 3 to 5 days and usually get better without you needing specific treatment.

Most cases of TD are the result of bacterial infection and are short-lived and self-limited. In addition to immunosuppression and sequential infection with diarrheal pathogens, ongoing infection with protozoan parasites can cause prolonged diarrheal symptoms.

Water or an oral rehydration solution is best. Drink at least 1 cup (240 milliliters) of liquid every time you have a loose bowel movement. Eat small meals every few hours instead of three big meals. Eat some salty foods, such as pretzels, crackers, soup, and sports drinks.
