Which medication is recommended for travelers to prevent traveler's diarrhea?

Rifaximin
Pepto-bismol
Loperamide
Azithromycin

The correct answer is: Pepto-bismol

Pepto-bismol is the recommended medication for travelers to prevent traveler's diarrhea. It contains bismuth subsalicylate which has antimicrobial activity against enterotoxigenic E. coli, one of the common causes of traveler's diarrhea. Pepto-bismol is effective in reducing the frequency and severity of diarrhea when taken preventatively before meals. Rifaximin is an antibiotic that can be used to treat traveler's diarrhea after symptoms develop but is not typically recommended for prevention due to concerns about antimicrobial resistance. Loperamide is an anti-diarrheal medication that can help with symptoms but does not prevent traveler's diarrhea. Azithromycin is an antibiotic that can be used to treat traveler's diarrhea in certain cases but is not typically used for prevention.
