Drug Description


Movicol is a prescribed medication used to alleviate occasional and chronic constipation, including severe cases such as fecal impaction characterized by a large, immovable mass of dry and hard stool within the rectum. 

As an osmotic laxative, Movicol softens and bulks up hard, dry stool by bringing water into the colon. This action triggers colonic activity and relieves constipation, making bowel movements comfortable. 

Uses and Dosage 

Before starting treatment with Movicol and with each prescription refill, carefully review its medication guide and patient information leaflet. Ask your doctor or pharmacist if you have any questions or uncertainties. 

Movicol is supplied as a powder in sachets, which should be mixed with the appropriate amount of water for optimal efficacy. It can be consumed with or without food at any time. 

To properly prepare the solution: 

  1. Open the sachet and empty its contents into a glass. 
  2. Add approximately 125ml or ¼ pint of water to the glass. 
  3. Stir the mixture thoroughly until all the powder is completely dissolved, resulting in a clear or slightly hazy solution. 
  4. Drink the solution. 

The usual dosing regimen for Movicol is provided below. If your doctor has prescribed a different regimen, strictly follow their instructions. 

  • To relieve constipation: Dissolve one sachet of Movicol in 125 ml of water and take it 1-3 times daily based on the severity of your condition.  
  • For fecal impaction, confirm the diagnosis before taking Movicol. Use 8 sachets per day dissolved in 125ml of water, taken within 6 hours for up to 3 days if needed. Those with a heart condition should not exceed 2 sachets per hour. 

Maintain adequate fluid intake while using Movicol. The fluid content of this medication should not be considered a substitute for your usual liquid consumption.
