Question: is alka seltzer good for diarrhea?
Answer: Treats diarrhea. One day is too many days to have diarrhea. Having Imodium (Loperamide) on hand to relieve your symptoms can be a life-saver. Alka-Seltzer (aspirin / citric acid / sodium bicarbonate) is a great option if you have an upset stomach and a headache or body aches at the same time.
