Q) How does LACTULOSE work?
A) LACTULOSE belongs to medications called laxative. LACTULOSE works by making the stool softer and easier to pass by drawing water into the bowel. Thus, LACTULOSE helps in treating constipation.

Q) Does LACTULOSE cause electrolyte imbalance?
A) Yes, LACTULOSE may cause electrolyte imbalance when used for long-term. Please do not take LACTULOSE more than the prescribed dose as it may cause serious side-effects. Always follow your doctor’s advice before taking LACTULOSE.

Q) Is LACTULOSE a laxative or stool softener?
A) LACTULOSE acts as both. It acts as a laxative which is used to treat constipation by increasing the number of bowel movements per day and as a stool softener that works by increasing stool water content and helps in softening the stool.

Q) Does LACTULOSE make you gain/lose weight?
A) No, LACTULOSE is not reported to cause weight gain or weight loss because it is not digestible and has no nutritional value. The common side effects of LACTULOSE are abdominal cramp and flatulence (gas).

Q) Does LACTULOSE increase blood sugar level?
A) There is no reported episode of increase in blood sugar level while taking LACTULOSE. Some people may think LACTULOSE and lactose are same but LACTULOSE is a synthetic sugar that is broken down in the colon into products that pull water from the body into the colon. As LACTULOSE is broken down in the colon, it is not absorbed in intestine and therefore has very little effect on glucose levels.

Q) Can I take LACTULOSE for long-term?
A) No, you are advised not to use LACTULOSE for long-term as it may lead to diarrhoea, electrolyte imbalance and disturbance to your normal bowel movement pattern. You are advised to speak to your doctor if you have been suffering from constipation from a long time. He/she may prescribe you alternative medication or modify your diet.

A) No, taking any medication more than prescribed dose leads to side-effects and sometimes likely turns into serious adverse effects. In case of overdosage, you may experience abdominal pain and diarrhoea. Contact your doctor if you have taken LACTULOSE more than you should.
