For Diarrhea

• Attapulgite (Kaopectate) helps to control diarrhea. You should not use it for more than 2 days unless directed by a doctor.
  
  
• Loperamide (Imodium A-D) is a good medicine for diarrhea. It does not treat upset stomach, though. If used too much, it can cause constipation, and even dependency, so be careful. But a few days of treatment are basically harmless.
  
  
• Bismuth subsalicylate (Pepto-Bismol) is a good first-line treatment for intestinal problems. It is a safe and effective treatment for mild diarrhea. It also helps for nausea and indigestion. Like aspirin, taking this when you have certain viral infections can cause Reye syndrome. You should not take this if you have fever or chickenpox.
