Docusol Paediatric Solution Docusol Paediatric Solution is a laxative used to prevent & treat constipation in children aged 6 months to 12 years. It may also be used before a stomach x-ray. Docusol Paediatric Solution contains the active ingredient docusate sodium which works by softening the stool in the bowel, making it easier to pass. It also causes the muscles in the intestinal wall to contract more often & with increased force, helping to move the contents of the intestine through the colon to the rectum so that the bowel can be emptied. Docusol Paediatric Solution is strawberry flavoured.
