Micralax is indicated whenever an enema is necessary to relieve constipation: in dyschezia, especially in bedridden patients; in geriatrics, paediatrics and obstetrics; and in preparation for X-ray examination, proctoscopy and sigmoidoscopy.

4.2 Posology and method of administration

Adults and children aged 3 years and over: Administer the contents of one micro-enema rectally, inserting the full length of the nozzle. No lubricant is needed as a drop of the mixture is sufficient.

Micralax usually works within 5 to 15 minutes, so make sure you are near a toilet before using it.

Always use a fresh tube of Micralax every time.

1. Lie down on your side with your knees drawn up towards your tummy or, if you prefer, sit on the toilet.

2. Pull or twist the cap off the tube.

3. If you want to lubricate the nozzle before inserting it, squeeze a drop of liquid out onto the nozzle.

4. Insert the full length of the nozzle into your back passage.

5. Gently squeeze the tube until it is empty.

6. Keep squeezing the tube as you pull the nozzle out of your back passage. This is to stop the medicine being drawn back into the tube.
