Cancer: Home Treatment for Nausea or Vomiting


The best way to control nausea and vomiting is to start treating it before you start your cancer treatment. Your doctor may give you medicines to control nausea. There are also home treatments that can help you manage these symptoms.

  • Take anti-nausea medicines as your doctor recommends.
    • Be sure to tell your doctor if you still have problems after your treatment. Your doctor may adjust your medicine.
    • If your doctor hasn't prescribed anti-nausea medicine, ask about taking an over-the-counter medicine, such as dimenhydrinate (Gravol), or an antihistamine, such as Benadryl.
  • Try eating before your treatment.
    • Having a light meal or snack before treatment may help prevent nausea. Stay away from foods that may make you feel sick, such as fried, spicy, sweet, or salty foods.
    • If you have nausea during your treatment, try eating earlier—at least an hour or two before your next treatment. After your treatment, you may want to wait 1 hour or more before you eat again.
  • Try peppermint or ginger.
    • Use real ginger, such as candied ginger or ginger tea. Real ginger (not ginger flavouring) helps to reduce nausea.
    • Suck on peppermint candy, or chew peppermint gum. Peppermint may relax tight muscles in your stomach and help decrease the stomach contractions that may be causing your nausea.
  • Drink plenty of water.
    • Make sure you get enough liquids so that you don't get dehydrated. Take frequent small sips of water if a whole glass is too much.
    • Drink fluids with your meals and 1 hour before or after meals.
  • Try distraction or relaxation techniques if you have nausea right before treatment.

    Some people feel sick right before their treatments. For this kind of nausea, medicine doesn't seem to work well. It may help to:

    • Distract yourself. Try playing video games, reading, working a crossword puzzle, or doing something else that you enjoy.
    • Use deep breathing, guided imagery, or other relaxation techniques.
  • Take care of yourself if you are vomiting.
    • Rinse your mouth with water and brush your teeth after you vomit.
    • After vomiting has stopped for 1 hour, sip a rehydration drink, such as Pedialyte or Rehydralyte.
    • Drink plenty of fluids to prevent dehydration. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
    • Choose water and other clear liquids until you feel better. Try clear fluids, such as apple or grape juice mixed to half strength with water, dehydration drinks, weak tea with sugar, clear broth, and gelatin dessert such as Jell-O. Do not drink citrus juices.
    • Get extra rest until you feel better.
    • When you feel better, start eating clear soups and mild foods until all symptoms are gone for 12 to 48 hours. Other good choices include dry toast, crackers, cooked cereal, and gelatin dessert.

Symptoms to watch for during home treatment

Call 911 anytime you think you may need emergency care. For example, call if:

  • You passed out (lost consciousness).

Call your doctor or nurse advice line now or seek immediate medical care if:

  • You have a fever.
  • You can't keep down fluids or medicines.
  • You think you are dehydrated.
  • You have new or worse belly pain.

Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if:

  • You have nausea and vomiting that doesn't go away after you take anti-nausea medicine.
  • You do not get better as expected.
