Expert advice

  • Avoid taking a Lactulose for more than 1 week, unless prescribed by the doctor, as it leads to dependency on the laxative action to produce a bowel movement. 
  • Together with Lactulose, fiber rich diet containing whole grain bread and cereals, bran, fruits and green leafy vegetables, is essential to maintain healthy bowel function.
  • A Lactulose should preferably be taken at bedtime because it requires 6 to 8 hours to show impact.
  • Notify your doctor if you are on a low-sugar diet because the Lactulose contains sugars.
  • Take Lactulose after 2 hours from other medicines, as it may interfere with the absorption of other medicines.
