The general goals of treatment of cyclic vomiting syndrome (CVS) are: interruption of established episodes, amelioration of symptoms in patients whose episodes cannot be interrupted, aborting episodes during prodromal symptoms, prophylaxis to abolish or lessen the frequency of episodes, and recovery. Complications of cyclic vomiting episodes include esophagitis, hematemesis, depletion of intracellular electrolytes, hypertension, and secretion of inappropriate antidiuretic hormone.
