Directions of use for Movicol Half Powder Sachets

This medicine can be taken at any time of day with or without food.
Dissolve the content of each sachet in 62.5ml (¼ glass) of water and drink.

Chronic Constipation:
A dose of Movicol-Half is 2 sachets. Each sachet is dissolved in 62.5ml (1/4 glass) of water. Take 1 –3 times a day depending on the severity.

Faecal impaction:
Before you take Movicol-Half for faecal impaction, it should be confirmed that you have this condition. A dose of 16 sachets a day of Movicol-Half is needed for the treatment of faecal impaction. Each sachet dissolved in 62.5ml (1/4 glass) of water. The 16 sachets should be taken within 6 hours for up to 3 days if required.

How to mix
Open the sachet and pour the contents into a glass. Add ¼ glass (about 62.5ml) of water to the glass. Stir well until all the powder has dissolved and the Movicol-Half solution is clear or slightly hazy, then drink it. If you like you can add a flavour such as orange squash to the drink.

For use in faecal impaction, the correct number of sachets can be reconstituted in advance and kept covered and refrigerated for up to 6 hours. For example, 16 sachets can be made up of one litre of water.
