Abstract

Gastrointestinal symptoms such as eructation, borborygmi, flatus, abdominal distension and pain are often attributed to excess gas¹ although such a relationship has been difficult to prove.² Dimethicone is promoted as a defoaming agent for relief of abdominal pain due to retained gas and for “colic” in infants. It has been suggested that it may provide mucosal protection³ and it is included in many combined antacid preparations. It is also used to improve visibility during endoscopy. This article reviews the actions and clinical uses of dimethicone.
