Cyclic vomiting syndrome

Cyclic vomiting syndrome is a condition characterized by discrete episodes of intractable vomiting with periods of weeks or months without any symptoms. Attacks may also recur with nausea and abdominal pain, headaches, or migraines. Cyclic vomiting syndrome typically develops during childhood, usually between ages 3 and 7; although it often remits during adolescence, it can persist into adult life. Abortive treatment for cyclic vomiting episodes includes anti-emetics such as ondansetron, and prophylaxis includes anti-migraine drugs such as sumatriptan and amitryptiline.
