Lansoprazole (Prevacid) is a medicine that is used to decrease the amount of acid that is made by the stomach.

It may be used to treat ulcers, gastroesophageal reflux (GER or GERD) and heartburn.

It is available as capsule, and as an oral disintegrating tablet. Your pharmacy may also be able to make a liquid for you.

  • The capsule may be opened and mixed with a small amount of applesauce immediately before taking. Do not crush or chew the granules.
  • If your child has an NG-tube or G-tube you may also be able to mix the beads from the inside of the capsule in acidic juice such as apple, cranberry, grape, orange, grapefruit, pineapple, prune, tomato, or V8 before giving through the tube.
