If possible, the underlying cause of vomiting is corrected by surgery or other means. However, this is not possible for many causes of vomiting, and symptomatic treatment with antiemetics is used to relieve distress and minimize further fluid and electrolyte loss. Prolonged vomiting may cause dehydration, metabolic alkalosis, and hypokalemia. Hypomagnesemia also occurs and may need correction before the plasma potassium concentration can be maintained. Infusion of 0.9 per cent saline with potassium and magnesium supplements is usually sufficient to correct dehydration.

Clinical trials can be used to guide antiemetic treatment. However, there appears to be considerable variation in the effects of different antiemetics in patients with similar causes of vomiting. Antiemetics include prokinetics, phenothiazines, butyrophenones, antihistamines, anticholinergics, and 5-HT 3 receptor antagonists.
