Why is this medication prescribed?

Lansoprazole is used to prevent ulcers and to treat other conditions in which the stomach produces too much acid.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

Lansoprazole comes as an extended-release (long-acting) capsule and granules to make an extended-release oral solution (liquid) to take by mouth. Lansoprazole is usually taken once a day, before a meal. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lansoprazole exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

The capsule should be swallowed whole. If you have difficulty swallowing capsules, lansoprazole capsules can be opened, and the granules can be sprinkled on 1 tablespoon of applesauce, Ensure pudding, cottage cheese, yogurt, or strained pears and swallowed immediately. The capsules can also be emptied into 2 ounces of orange juice or tomato juice, mixed briefly, and swallowed immediately. Rinse the glass with some additional juice and drink immediately. The granules should not be chewed or crushed.

For patients who have a nasogastric tube, lansoprazole capsules can be opened and the granules mixed in 40 mL of apple juice. The mixture should be injected through the nasogastric tube into the stomach. Then the tube should be flushed with some more apple juice.

To use lansoprazole oral solution, empty the contents of a packet into a container with 2 tablespoons of water. Stir well and drink immediately. If any granules remain, add more water, stir, and drink immediately. Do not use liquids or foods other than water. Do not crush or chew the granules.

Continue to take lansoprazole even if you feel well. Do not stop taking lansoprazole without talking to your doctor.
