    Expert advice for Lansoprazole

    • It is a well-tolerated medicine and provides relief for a long time.

    Frequently asked questions for Lansoprazole


    Q. What are the side effects of Lansoprazole use in infants?

    Use of Lansoprazole in infants (children < 1 year of age) may commonly cause diarrhea, constipation, stomach upset, and flatulence. It may make infants irritable and inconsolable and difficult to sleep. Long-term use may cause inflammation of the pancreas, irritable colon, stool discoloration, growth of fungus in food pipe, stomatitis, abdominal swelling, mucosal atrophy of the tongue and decrease absorption of vitamins and minerals. Some may have severe allergic reactions also.

    Q. How is Lansoprazole given through the nasogastric tube?

    Open the Lansoprazole capsule and empty the granules into a syringe. Mix the contents with apple juice in the syringe and attach it to the nasogastric (NG) tube and give directly into the stomach. Once given, flush the NG tube with more apple juice to clear the tube.

    Q. Does long term use of Lansoprazole is associated with side effects?

    Patients taking Lansoprazole for a long period of time (a year or longer) may have decreased calcium levels leading to an increased risk of fractures of the hip, wrist, or spine. It can also decrease magnesium levels when used for more than 3 months. Long-term use may also cause inflammation of stomach lining (atrophic gastritis). Take Lansoprazole only at the dose and for duration advised by your doctor

    Q. Why does Lansoprazole cause diarrhea?

    Use of Lansoprazole lowers the natural stomach acid which normally helps to kill bacteria. So, use of Lansoprazole leads to overgrowth of the harmful bacteria which can cause diarrhea. This is known as Clostridium difficile–associated diarrhea (CDAD). Inform your doctor if you have loose stools many times in a day and for many days with stomach cramps and fever.

    Q. Does Lansoprazole increase appetite (make you hungry)?

    Yes, Lansoprazole can increase appetite and make you feel hungry. This is reported to be an uncommon side effect seen with the use of Lansoprazole.

    Q. Can Lansoprazole cause weight gain?

    Weight gain is reported in less than 1% of the patients taking Lansoprazole but the exact cause is unknown. One of the possible explanation is higher food intake once the reflux symptoms are relieved. Lifestyle modifications such as proper diet and avoidance of overeating should be observed to avoid weight gain.

    Q. Does Lansoprazole treat irritable bowel syndrome (IBS)?

    Lansoprazole is not routinely used for the treatment of irritable bowel syndrome (IBS). It is given if there is associated dyspepsia or increased stomach acid secretion. IBS is managed with a combination of antispasmodics (to relieve stomach pain), laxatives (to relieve constipation), and anti-motility drugs (to relieve diarrhea).

    Q. While taking Lansoprazole, which foods should be avoided?

    You should preferably avoid foods that cause acidity and heartburn as they would aggravate your disease condition, for example: fried foods, prepared in butter or oil, fat rich foods, tomato-based foods and juices, caffeinated drinks like cola, tea, drinks from citrus fruits like lemon water or orange juice and alcohol-containing drinks.

    Q. Is Lansoprazole used for children?

    Yes, Lansoprazole is used in the management of gastroesophageal reflux disease (GERD) and erosive gastritis in children. However, the safety and effectiveness of Lansoprazole are established only in children between 1 to 17 years of age.
