Anticipate Aemcolo Will Have a Limited Role for Travelers' Diarrhea

New Rx Aemcolo (em-COH-loh, rifamycin) will raise questions about treating travelers' diarrhea in adults.

Think of Aemcolo as similar to Xifaxan (rifaximin). Both meds work locally in the intestines and are minimally absorbed.

But don't jump to Aemcolo or Xifaxan for travelers' diarrhea. They're only effective against noninvasive E. coli strains that don't cause fever or bloody stools...and the bug usually isn't known.
