Lactulose Solution 500ml Lactulose is used to treat constipation, which affects almost everyone at some time in their life. This is often caused by a change of diet, a lack of exercise, as a side effect to some medications & some diseases. It is important to remember that constipation can cause complications if it is left without treatment for too long. Lactulose is not metabolised or absorbed by the body. The bacteria in the colon or large bowel break the lactulose down into acids. This causes water to be pulled into the colon which results in the softening of the stool. Lactulose also promotes peristalsis (pushing food through the body). Lactulose Solution is most commonly used by nursing mothers, children with constipation, surgery outpatients, pregnant women, elderly people or people with sever and/or chronic constipation. It may take 24-72 hours for it to take effect. To reduce the likelyhood of having constipation, drink plenty of water, exercise regularly & eat plenty of fibr.
