WebMD reports that Gas-X contains simethicone, which works to break up gas bubbles in the digestive system. This feature of simethicone provides relief to individuals who suffer from flatulence, bloating and gas pain. The maximum dosage for adults is 500 milligrams per day. It is important to contact a physician if Gas-X does not relieve symptoms or if symptoms worsen.
