Answer: Acetaminophen (Tylenol): Take for pain or fever. This is recommended over aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), which can upset the stomach. Over-the-counter (OTC) anti-diarrheal medications: Loperamide hydrochloride (Imodium) or bismuth subsalicylate (Pepto-Bismol) can help relieve diarrhea.
