What is cancer-related diarrhea?

Cancer-Related Diarrhea

How can you care for yourself if you have diarrhea during cancer treatment?

  • Before you take any type of over-the-counter medicine, tell your doctor that you are having diarrhea. If your doctor prescribes diarrhea medicines, take them exactly as directed. Call your doctor if you have any problems with your medicine.
  • Drink plenty of room-temperature fluids to prevent dehydration. Take frequent sips of water and other clear liquids until you feel better.
  • When you feel like eating, start with small amounts of food.
  • Rest when you feel tired.
