Behavioral interventions in treating anticipatory nausea and vomiting.

Anticipatory nausea and vomiting (ANV) is associated with a significant reduction in the quality of life for many chemotherapy patients. The use of 5-hydroxytryptamine type 3 receptor antagonists provides some relief for chemotherapy-induced nausea and vomiting, but does not seem to control ANV. Nonpharmacologic approaches, which include behavioral interventions, may provide the greatest promise in relieving symptoms. Little evidence supports the use of complementary and alternative methods, such as acupuncture and acupressure, in relieving ANV. Behavioral interventions, especially progressive muscle relaxation training and systematic desensitization, should be considered important methods for preventing and treating ANV.
