Diarrhea and Chemotherapy
Your physician may prescribe a medication to control your symptoms, and/or, if symptoms persist, you may need fluid replacement intravenously (IV). It is possible to replace these fluids intravenously on an outpatient basis. When you are having chemotherapy, you should not take any over-the-counter medications for diarrhea without first consulting your physician.
