WHY is this medicine prescribed?

Dexlansoprazole is used to treat gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and possible injury of the esophagus (the tube between the throat and stomach). Dexlansoprazole is used to treat the symptoms of GERD, allow the esophagus to heal, and prevent further damage to the esophagus. Dexlansoprazole is in a class of medications called proton pump inhibitors. It works by decreasing the amount of acid made in the stomach.

HOW should this medicine be used?

Dexlansoprazole comes as a delayed-release (releases the medication in the intestine to allow some of the medication to be released about 1 hour after it is taken and some of the medication to be released 4 to 5 hours later) capsule to take by mouth. It is usually taken once a day. Dexlansoprazole may be taken with or without food, but it may provide more relief from after-meal symptoms if it is taken before a meal. Take dexlansoprazole at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dexlansoprazole exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.

You should not chew or crush dexlansoprazole capsules. You can swallow the capsules whole, or you can open the capsule, sprinkle the contents on 1 tablespoon of applesauce, and swallow immediately without chewing.

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

If your condition does not improve or gets worse, call your doctor.
