Lansoprazole

What is Lansoprazole (Prevacid)?

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.

Do not crush or chew the capsules or tablets. The drug may not work if the capsule or tablet is crushed or chewed.
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. Do not crush the beads. Flush tube with additional juice.
Place the orally disintegrating table on the tongue and allow to disintegrate with or without water until the particles can be swallowed. Do not chew or crush the particles.
Some patients who cannot swallow capsules or tablets may be able to take a liquid form of lansoprazole prepared by the pharmacy. This form may be given through a G-tube, NG-tube, or J-tube. Flush the tube well.
This medicine works best if taken before eating. Antacids may be taken with lansoprazole if your child's doctor instructs you to give them.
Store at room temperature away from moisture and sunlight. Do not store in the bathroom.
If too much medication is taken by accident, call the Drug and Poison Information Center (DPIC), 513-636-5111 or your child's doctor right away.
