Micralax micro-enema contains sodium citrate, sodium alkyldulphoacetate, sorbic acid, sorbitol and glycerol.

How does it work?

  • Micralax micro-enema contains sodium citrate, sodium alkyldulphoacetate, sorbic acid, sorbitol and glycerol.
  • Sodium citrate is an osmotic laxative that works by causing water to be drawn into the large bowel. It increases the water content and volume of the bowel contents, which softens the stools and also stimulates the bowel to contract and move its contents along to the rectum.
  • Glycerol works by irritating the nerves in the bowel wall.
These nerves make the muscles in the bowel contract harder and more often, which helps move the stools along.
  • Sodium alkylsulphoacetate helps to lubricate the stools.
  • Sorbic acid and sorbitol both also have a laxative effect.
  • The combined action of these laxatives helps to soften hard stools and relieve constipation without straining.
  • How do I use it?

    • This medicine is for rectal use only and must not be taken by mouth.
    • After removing the cap from the nozzle on the tube, squeeze out a drop of the solution to lubricate the tip of the nozzle. Gently insert the full nozzle into the back passage (rectum). Squeeze out the entire contents of the tube into the rectum and then gently remove the nozzle, still squeezing the tube tightly. Dispose of the tube carefully.
    • Each tube is for single use only.


    • Prolonged use of this medicine should be avoided. If symptoms persist, you need to use a laxative every day, or if you have persistent abdominal pain, you should consult your doctor for advice. Prolonged use may also affect the absorption of some vitamins and cause diarrhoea and fluid loss.
