Alcid MPS Liquid is a therapeutic digestive medication containing a balanced mix of Aluminium hydroxide, Dimethicone and Magnesium hydroxide. Role of key ingredients: Aluminium hydroxide is an antacid, which neutralises increased stomach acid. Dimethicone reduces flatulence and relieves abdominal pain or discomfort, which is due to excessive gas in the digestive tract. Magnesium hydroxide is a laxative that increases water in the intestine and reduces stomach acid. Alcid MPS Liquid is helpful in providing relief from peptic ulcer, gastritis, heartburn, oesophagitis, and other dyspeptic conditions associated with hyperacidity. Directions of use: For immediate effect, consume 1-2 teaspoonful of Alcid after meals. Use after properly shaking the bottle. Use under Medical supervision.
