What is Movicol?

Movicol is a type of laxative that’s available in a range of different forums, including Movicol liquid, powder sachets, and ready-to-drink packets. Movicol liquid and sachets contain something called Polyethylene Glycol, which is an osmotic laxative. Movicol also contains sodium bicarbonate, as well as sodium chloride and potassium chloride.

Movicol constipation medicine works by passing through the gut without being fully absorbed into your body. Movicol causes water to be retained by the bowel, while increasing the water content of the stools, allowing them to pass more easily.

Movicol can also stimulate the muscles in the walls of the bowel to push the stools out of the body.

The combination of sodium chloride, sodium bicarbonate, and potassium chloride contained within Movicol also ensure that this constipation medicine doesn’t cause the body to lose or gain significant amounts of potassium, water or sodium.

Movicol will not cause you to immediately evacuate your bowels. It can often take one or two days before this constipation medicine works.
