Indications & Uses

Flatulence, abdominal distention, fullness, gas and windy colic: Flatulex is an excellent and effective antiflatulent, used to relieve the painful symptoms of excess gas in the digestive tract. Such gas is often caused by swallowing air or eating certain foods that disagree with the digestion. Flatulex drop is especially suited for infants, acting in the stomach and intestines to help release gas more easily through belching or passing flatus. In large bowel preparation, adding Flatulex to a polyethylene glycol bowel preparation produces symptomatic improvement prior to investigation. It also has an anecdotal use as an antifoaming agent in managing accidental ingestion of foaming detergents.
