Buying advice

When choosing an antidiarrheal, consider the cause (viral, bacterial, or travel-related) and your symptoms (e.g., gas, cramps). Loperamide (Imodium) is best for stopping diarrhea quickly, while bismuth subsalicylate (Pepto-Bismol) soothes the stomach. For prevention or gut health, probiotics are a good option but not immediate. Always check for allergies and contraindications (e.g., salicylate sensitivity). Price range varies from $5 to $40; generics are budget-friendly.
