Dimethicone for gastrointestinal symptoms?


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.
