Side Effects

Managing Nausea and Vomiting at Home

Frequent vomiting can be dangerous because it can lead to dehydration. It can also lead to inhaling food or liquids, which can cause choking and other problems.

Be sure to tell your cancer care team if you have nausea or are vomiting because there are medicines that can help. These medicines should be taken on a regular schedule, or as needed, as prescribed by your doctor. And if a certain drug doesn’t work, your cancer care team may be able to recommend another one. It may take a few tries to find the medicines that work best for you. Talk with your cancer care team about what's causing your nausea and vomiting and what you can do about it.

What to look for

  • Changes in eating habits
  • Foul mouth odor
  • Yellow or green foul-smelling fluids on bedclothes
  • Feeling queasy or having an upset stomach
  • Increased saliva, clamminess, and sweating that may come before vomiting

What to eat or not eat when you have nausea

  • Eat the foods you like and those that sound good to you. For example, some people develop a dislike for red meat and meat broths during treatment. In that case, try other protein sources, such as fish, chicken, beans, and nuts.
  • If the nausea only happens between meals, keep something in your stomach. Eat frequent, small snacks throughout the day. Snack ideas include smoothies, trail mix, and fruit.
  • Do not skip meals or snacks. If your stomach is empty, your nausea might be worse.
  • On chemotherapy treatment days, eat a small meal or snack before treatment.
  • Try to avoid eating your favorite foods when you have nausea. If you eat foods you like when you are nauseated, you could find them unappealing when treatment is over because you associated them with feeling sick.
  • Sip liquids slowly throughout the day. You may find it easier to tolerate cold and clear liquids (Clear liquids are those you can see through, such as ginger ale, apple juice, broth, tea, etc.)
  • Also try popsicles or gelatin. Suck on hard candy with pleasant smells, such as lemon drops or mints, to help get rid of bad tastes. (Don’t eat tart candies if you have mouth sores.)
  • Eat bland foods, such as dry toast and crackers.
  • Eat food cold or at room temperature to decrease its smell and taste. 
  • Avoid fatty, fried, spicy, or very sweet foods.
  • Try small amounts of foods high in calories that are easy to eat (such as pudding, ice cream, sherbets, yogurt, and milkshakes) several times a day. 
  • Use butter, oils, syrups, sauces, and milk in foods to raise calories. 
  • Avoid low-fat foods unless fats upset your stomach or cause other problems.
  • Tart or sour foods may be easier to keep down (unless you have mouth sores).

    For vomiting

    • If you are in bed, lie on your side so that you won’t inhale the vomit.
    • Ask that medicines be prescribed in the form that would be easiest for you to tolerate, such as dissolving tablets or suppositories, if possible. To prevent vomiting, take the medicine at the first hint of nausea.
    • Wait for the vomiting to stop before eating or drinking anything. After vomiting stops, start taking in small amounts of clear liquids slowly and increase as tolerated.
    • Sit upright after vomiting.
    • Try liquids in the form of ice chips or frozen juice chips, which can be slowly dissolved in your mouth.

    Complementary or alternative (non-drug) treatments for nausea and vomiting

    Other things you can do if you have nausea

    • Try to rest quietly while sitting upright for at least an hour after each meal.
    • Distract yourself with soft music, a favorite TV program, or the company of others
    • Tell your cancer team about the nausea, because there are many drugs that can help it.
    • Take your anti-nausea medicine at the first signs of nausea to help prevent vomiting.
    • While waiting for your nausea medicine to work, relax and take slow, deep breaths.
    • Try some non-drug treatments for nausea and vomiting

    Anti-nausea and vomiting drugs (anti-emetics) are the main treatments for nausea and vomiting, but some non-drug treatments can also be used. These involve using your mind and body with the help of a qualified therapist.

    Non-drug treatments may be used alone for mild nausea, and are often helpful for anticipatory nausea and vomiting. These methods can be used with anti-nausea and vomiting medicines for a person whose cancer treatment is likely to cause nausea and vomiting. If you’d like to try one or more of these methods, ask a member of your cancer care team if the methods are safe for you and to refer you to a therapist trained in these techniques.

    These methods try to decrease nausea and vomiting by:

    • Helping you feel relaxed
    • Distracting you from what’s going on
    • Helping you feel in control
    • Making you feel less helpless

    Below are some non-drug methods that have helped some people. Most of them have few or no side effects. Before using any of these treatments, check with your cancer care team to see if they are safe for you. Ask your cancer care team what non-drug treatments they may have available and which ones they can recommend.


    Hypnosis can be used to make behavior changes to control nausea and vomiting. It creates a state of intense attention, willingness, and readiness to accept an idea. It is done by a trained specialist.

    Relaxation techniques

    Relaxation techniques such as meditation (focusing the mind), breathing exercises, or progressive muscle relaxation (tensing and relaxing the muscles) can help decrease nausea and vomiting.


    Biofeedback helps people reach a state of relaxation. It uses monitoring devices to help people gain conscious control over physical processes that are usually controlled automatically. Using biofeedback, a person learns to control a certain physical response of the body, such as nausea and vomiting. This is done by tuning in to the moment-to-moment body changes that are linked to the physical response. For example, biofeedback can be used to prevent skin temperature changes, such as those that often happen before nausea and vomiting starts. Biofeedback alone has not been found to work as well as for nausea and vomiting as the combination of biofeedback and progressive muscle relaxation.

    Guided imagery

    Guided imagery lets people mentally remove themselves from the treatment center and imagine that they are in a place that’s relaxing for them. The place can be a vacation spot, a room at home, or some other safe or pleasant place. While trying to imagine what they usually feel, hear, see, and taste in the pleasant place, some people can mentally block the nausea and vomiting.

    Systematic desensitization

    Systematic desensitization helps people learn how to imagine an anxiety-producing situation (such as nausea and vomiting) and reduce the anxiety related to the situation. In most cases, what a person can imagine without anxiety, they can then experience in the real world without anxiety.

    Acupuncture or acupressure

    Acupuncture is a traditional Chinese technique in which very thin needles are put into the skin. There are a number of different acupuncture techniques, including some that use pressure rather than needles (acupressure). Acupuncture or acupressure can help with nausea.

    Music therapy

    Specially trained health professionals use music to help promote healing.. Music therapists may use different methods with each person, depending on that person’s needs and abilities. There’s some evidence that, when used with standard treatment, music therapy can help to reduce nausea and vomiting due to chemo.


    What caregivers can do

    • When the patient feels nauseated, offer to make meals or ask others to make meals to reduce bothersome food odors. Use kitchen vent fans to reduce smells.
    • Cover or remove foods with strong or unpleasant smells.
    • Use plastic forks and spoons rather than metal ones, which may cause a bitter taste..
    • Ask about medicines to help prevent vomiting.
    • Watch the patient for dizziness, weakness, or confusion.
    • Try to help the patient avoid constipation and dehydration by encouraging them to sip on clear liquids slowly throughout the day. Either of these can make nausea worse.

    Call the cancer care team if the patient

    • Might have inhaled some of the vomited material
    • Is vomiting over a period of days,
    • Vomits blood or material that looks like coffee grounds
    • Cannot take in more than 4 cups of liquid or ice chips in a day or hasn’t eaten for more than 2 days
    • Can’t take medicines
    • Becomes weak, dizzy, or confused
    • Loses 2 or more pounds in 1 to 2 days (This means they are losing water quickly and might be getting dehydrated.)
    • Has dark yellow urine and doesn’t urinate as often or as much
