Expert advice for Relux Liquid
Avoid taking a Relux 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 Relux, fiber rich diet containing whole grain bread and cereals, bran, fruits and green leafy vegetables, is essential to maintain healthy bowel function. A Relux 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 Relux contains sugars. Take Relux after 2 hours from other medicines, as it may interfere with the absorption of other medicines.
