Note the following:

  • The condition is usually self-limited (3-5 d).

  • Onset is within 1 week of arrival.

  • Fever, vomiting, and bloody stools are uncommon.

  • Early treatment may decrease duration.

  • Loperamide is often useful.

  • If a lack of response to antibiotics is present, check for parasites.

  • Consider C difficile in patients taking antibiotics.

  • The use of probiotics, such as Lactobacillus GG, has had mixed results in treatment and prevention.

  • Rifaximin at 200 mg PO tid may be used for the treatment or prevention of travelers' diarrhea. [21]
