These specialists determined what medications have worked best and made recom- mendations to help you and your doctors make decisions about your continuing health care. It’s important to remember, however, that every person who is treated for cancer is different, and these guidelines are not meant to replace your or your doctors’ judgment.
The final decisions you and your doctors make will be based on your The information in this booklet will help you to understand what antiemetic drugs are and how they may be used as part of your cancer
treatment. Antiemetic drugs are used to help prevent emesis, otherwise
known as vomiting (throwing up), and to relieve nausea (the feeling of being sick to your stomach). Nausea and vomiting is a common side effect of chemotherapy and, sometimes, radiation therapy (radio-
therapy). Many patients fear these side effects, which, up until now,
have been difficult to control. There are now newer drugs that help patients feel better while they are being treated for cancer.

Nausea and Vomiting Caused by Chemotherapy Not every patient who has chemotherapy will have nausea and
. Some patients are more likely than others to have this
symptom. For example, it is more common in women, young patients, patients with a history of excessive alcohol use, and in patients who have had chemotherapy before and had nausea and vomiting that Chemotherapy Drugs that Cause Nausea and Vomiting Usually, your doctor will prescribe an antiemetic drug before yourchemotherapy if you will be treated with a chemotherapy drug that sometimes or often causes nausea and vomiting. If you will receive a chemotherapy drug that rarely causes nausea and vomiting, your doctor will probably prescribe an antiemetic drug to be taken only if you become sick while you are being treated. Some chemotherapy drugs often cause nausea and vomiting, while others cause it less frequently or rarely, as outlined in the table below. Nausea and Vomiting Nausea and Vomiting Prevention and Treatment of Nausea and VomitingCaused by Chemotherapy The following antiemetic drugs are recommended to preventvomiting after treatment with chemotherapy drugs. These drugs can be given orally (by mouth) or intravenously (through a vein in your arm), and your doctor will decide which is best for you. Your doctor will probably suggest that you have a dose of one or more of these drugs before your scheduled
treatment with chemotherapy. He or she may give you a combination of different antiemetic drugs, but also may give you just one. If you will be given high-dose chemotherapy,
your nausea and vomiting may be more difficult to control, and your doctor will probably give you a higher dose of an antiemetic drug to help you feel better.
If your doctor thinks you may have vomiting for more than a day, he or she will probably suggest that you take a dose of one or more of these drugs several times a day for 2 to 4 days after Some patients may have anticipatory emesis or vomiting that
begins before a chemotherapy treatment. This type of vomiting
occurs in patients who have felt sick during chemotherapy in the past. Also, people who have motion sickness are more likely to have If your doctor thinks you may have developed anticipatory emesis, he or she might try to prevent it by prescribing an antiemetic drug to be taken a few days before your scheduled treatment with chemotherapy. If you still have anticipatory emesis, your doctor may suggest alternative ways to overcome this symptom. Be sure to tell your doctor if you continue to feel sick to your stomach or throw up even after taking an antiemetic drug. Your doctor can then adjust your medication to help you feel better.
Prevention and Treatment of Nausea and VomitingCaused by Radiation Therapy With radiation treatment for cancer, your body is exposed to only asmall dose of radiation for a very short time. Because of this, nausea and vomiting does not occur as often after radiation therapy as it does after chemotherapy. However, nausea and vomiting can be more likely after radiation treatment to certain areas on your body.
Your doctor will probably prescribe an antiemetic drug if you will have total-body irradiation (radiation treatment of your entire body),
hemibody irradiation (radiation treatment of half your body), or
cranial radiosurgery (an operation in which radiation is used to
destroy a tumor within the brain). You also may be given an antiemetic drug if you will have radiation treatment of the following Nausea and vomiting is not usually caused by radiation treatment of your skull (only), head and neck, breast, chest, arms or legs, or pelvis. Your doctor will probably prescribe an antiemetic drug to be taken only if you become sick after receiving radiation treatment The doses of antiemetic drugs given during chemotherapy or radiationtherapy sometimes cause side effects. Symptoms that have been associated with some of these drugs are slight headache, constipation,
trouble sleeping, restlessness, involuntary movements of the muscles and tongue, and sedation. Be sure to tell your doctor if you have any
of these symptoms or if you are at risk for hyperglycemia (high level

What are ulcers? They are a sore on the inside of the GI tract, either in the esophagus, stomach or duodenum (beginning of the small intestine).
