Question: can you take any medicine for stomach flu?
Answer: Your doctor may prescribe an antiemetic such as promethazine, prochlorperazine, metoclopramide, or ondansetron to stop the nausea and vomiting. You can also try an over-the-counter antidiarrheal medication, such as loperamide hydrochloride (Imodium) or bismuth subsalicylate (Pepto-Bismol).
