Frelax® Oral Emulsion is a combination of Magnesium Hydroxide and Liquid Paraffin which is recommended for the temporary relief of constipation. Magnesium Hydroxide retains water in the stomach lumen due to increased osmotic pressure. Liquid Paraffin acts as a mild laxative by softening stools thus easing defecation. Each amber colored glass bottle contains 100 ml of Frelax® Oral Emulsion. Each 5 ml contains Magnesium Hydroxide BP 300 mg and Liquid Paraffin BP 1.25 ml.
