• Patients must have a comprehensive evaluation to eliminate other causes of their symptoms. This includes a history and physical examination. A recent (within 3 years) evaluation of the upper GI tract with either upper endoscopy or upper GI radiographic series.

• Clinically significant electrolyte disorders. These include significant hypokalemia, hyperkalemia, hypomagnesemia, and hypermagnesemia that cannot be corrected with treatment of these electrolyte abnormalities.
• Gastrointestinal hemorrhage or obstruction.
• Presence of a prolactinoma (prolactin-releasing pituitary tumor).
