Many medications, medical conditions, and procedures can induce nausea and vomiting. Drugs that cause gastric irritation eg, nonsteroidal anti-inflammatory drugs, selective serotonin reuptake inhibitors, and antibiotics can cause nausea. Examples of drugs that stimulate the vomiting center indirectly through the CTZ are digoxin, morphine, alcohol, ipecac, and anti-cancer drugs. Motion sickness and inner ear disorders cause nausea by directly stimulating the vomiting center.
The same cervical mucus changes occur as with very low-dose progestogens. High-dose, progestogen-only contraceptivesвthe injectables Depo-Provera and Noristeratвcompletely inhibit follicular development and ovulation. Estrogen negative feedback on the anterior pituitary greatly decreases the release of FSH, which makes combined hormonal contraceptives more effective at inhibiting follicular development and preventing ovulation. Estrogen also reduces the incidence of irregular breakthrough bleeding. In a normal cycle, menstruation occurs when estrogen and progesterone levels drop rapidly. If withdrawal bleeding is not desired, combined hormonal contraceptives may be taken continuously, although this increases the risk of breakthrough bleeding. Breastfeeding causes negative feedback to occur on pulse secretion of gonadotropin-releasing hormone GnRH and luteinizing hormone LH. Depending on the strength of the negative feedback, breastfeeding women may experience complete suppression of follicular development, follicular development but no ovulation, or normal menstrual cycles may resume.
Food should be reintroduced gradually, beginning with small amounts of dry, bland food like crackers and toast. Medications that are given to relieve nausea and vomiting are called antiemetics. Meclizine Bonine , a medication for motion sickness, also diminishes the feeling of queasiness in the stomach. Dimenhydrinate Dramamine , another motion-sickness drug, is not effective on other types of nausea and may cause drowsiness. Newer drugs that have been developed to treat postoperative or postchemotherapy nausea and vomiting include ondansetron Zofran and granisetron Kytril. Another treatment that has been found to lower the risk of nausea after surgery is intravenous administration of supplemental fluid before the operation. Advocates of alternative treatments suggest biofeedback, acupressure and the use of herbs to calm the stomach. Biofeedback uses exercise and deep relaxation to control nausea. Acupressure applying pressure to specific areas of the body can be applied by wearing a special wristband or by applying firm pressure to the back of the jawbone the webbing between the thumb and index finger the top of the foot the inside of the wrist the base of the rib cage Acupuncture is another alternative treatment found to be effective in relieving nausea. A few people, however, experience nausea as a side effect of acupuncture. Chamomile Matricaria recutita or lemon balm Melissa officinalis tea may relieve symptoms. Ginger Zingiber officinale , another natural remedy, can be drunk as tea or taken as candy or powered capsules. Massage, meditation, yoga, and other relaxation techniques can help prevent stress-induced nausea.

Shared care information Different shared care centres will have different roles in the administration of chemotherapy to paediatric oncology children. In centres where more chemotherapy is administered, all patients should have antiemetic medication prophylactically administered as per the guideline regardless of whether they have nausea.
