[Travelers' diarrhea 1992].

Traveller's diarrhea is a common problem without consequences for a healthy patient. Correct information, especially about hygiene habits during the trip, is most important. The prescription of an anti-diarrheal medication is usually justified but should not be given without proper information about the possible dangers. A prophylactic antibiotherapy is very seldom necessary. Antibiotic self-medication can be a pragmatic alternative. Patients at risk must be identified before the trip, and appropriate measures are essential. Once the patient is back home again diarrhea will subside spontaneously and both patient and physician should therefore know to be patient.
