Movicol dosage

Constipation:

• Dissolve 1 sachet of Movicol in 125ml of water up to 3 times per day depending on the severity of your constipation.

Faecal impaction:

• Before commencing treatment for faecal impaction, speak to a doctor to confirm your condition.
• Take 8 sachets per day, consuming all 8 within 6 hours but no more than 2 sachets per hour, for up to 3 days.
• Dissolve each sachet in 125ml of water.

For full details of how to use Movicol, read the Patient Information Leaflet thoroughly.

Movicol can be used by children and adults over the age of 12 years to treat constipation and faecal impaction.

Each sachet must be mixed with up to 125ml of water and drunk. You must make sure to drink plenty of fluids throughout the day to avoid dehydration when taking Movicol.

What is the best time of day to take Movicol?

Most people will need to start by taking more than 1 Movicol sachet a day to treat constipation. It’s a good idea to spread out the doses: you could take one in the morning and another at night, for instance. If you’re taking 3 sachets per day, you can take one at noon.

If you’re using Movicol to treat faecal impaction, get clear advice from a doctor before commencing treatment for your condition. You’ll need to take 8 sachets per day for 3 consecutive days, and the 8 daily sachets must be consumed within a 6-hour period.

Movicol doesn’t need to be taken at a particular time of day, thankfully, so you can fit your doses around your schedule and your personal preferences.

How long does Movicol take to work?

Movicol powder sachets don’t work as quickly as stimulant laxatives such as Senna (which starts to work within 6-12 hours).

When taking Movicol as directed, most people will start to see their constipation improve within 1 to 3 days.

How long does Movicol stay in your system?

Some people may experience diarrhoea when taking Movicol, especially if they’re deliberately using large doses or have accidentally ingested too much. If you experience diarrhoea after using Movicol heavily, you should stop taking Movicol or reduce the number of sachets you’re ingesting until your poo solidifies (this may take a few days).

If you experience diarrhoea, drink plenty of fluids to avoid becoming dehydrated. If your diarrhoea persists to the point that you feel worried, get advice from a doctor or pharmacist.

Long-term use of Movicol

For the treatment of constipation, Movicol is usually taken for 2 weeks or until stools are consistently soft and easy to pass.

If you continue to be affected by constipation after using Movicol for 14 consecutive days then you should seek advice from a doctor or pharmacist.

As with all laxatives, it isn’t advisable to use Movicol long-term. If you’re suffering from persistent constipation, however, you may be advised to repeat your 2-week treatment course or continue using Movicol while reducing your dose to 1 sachet per day.
