How does this medication work? What will it do for me?
Psyllium fibre – calcium contains two active ingredients. Psyllium fibre belongs to two groups of medications: bulk-forming laxatives and cholesterol-lowering medications. Calcium belongs to a group called supplements. This combination medication is used to treat constipation, as a fibre supplement, to increase calcium intake, and to treat mild to moderately high cholesterol (when taken with a low-fat diet).
For the treatment of constipation, psyllium fibre – calcium works by absorbing water from the intestines to produce larger, softer stools. It usually works within 12 hours to 72 hours. Calcium is a mineral that is important to maintain bone health and prevent osteoporosis.
For the treatment of mild to moderately high cholesterol, it works by increasing bile acid loss from the body by trapping bile acids in the small intestine. This causes more bile to be produced. Since cholesterol is used in the production of bile acids, cholesterol levels in the blood are reduced when more bile acid is made.
