Question: what is the best medication to take for diarrhea?
Answer: In most cases, over-the-counter medication can be helpful in stopping an occasional bout of diarrhea — especially traveler's diarrhea, which may result from ingesting contaminated food or water while abroad. Over-the-counter options include Imodium (loperamide) and Pepto-Bismol or Kaopectate (bismuth subsalicylate).
