Laxido Orange contains macrogol 3350 and the electrolytes sodium chloride, sodium hydrogen carbonate and potassium chloride. Macrogol 3350 is a laxative used for the treatment of constipation, especially if you have been constipated for a long time. It is also used to treat a build-up of hard faeces in your bowel which may be a result of long-term constipation (this is known as faecal impaction). Macrogol 3350 makes your faeces softer and easier to pass, giving you relief from constipation. The electrolytes help to maintain your body’s normal levels of sodium, potassium and water while you are being treated for constipation.
