Don't Jump to Aemcolo 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 expect a limited role for 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.
