What is dexlansoprazole?
Dexlansoprazole is a proton pump inhibitor that decreases the amount of acid produced in the stomach.
Dexlansoprazole is used to treat heartburn caused by gastroesophageal reflux disease (GERD), and to heal erosive esophagitis (damage to the esophagus from stomach acid).
Dexlansoprazole may also be used for purposes not listed in this medication guide.
What is the most important information I should know about dexlansoprazole?
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
What should I discuss with my healthcare provider before taking dexlansoprazole?
Heartburn is often confused with the first symptoms of a heart attack. Seek emergency medical attention if you have chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating, and a general ill feeling.
You should not take dexlansoprazole if you are allergic to it, or if you also take a medicine that contains rilpivirine (Complera, Edurant, Odefsey).
To make sure dexlansoprazole is safe for you, tell your doctor if you have:
severe liver disease;
low bone mineral density (osteopenia); or
low levels of magnesium in your blood.
Taking a proton pump inhibitor such as dexlansoprazole may increase your risk of bone fracture in the hip, wrist, or spine. This effect has occurred mostly in people who have taken the medicine long term or at high doses, and in those who are age 50 and older. It is not clear whether dexlansoprazole is the actual cause of an increased risk of fracture.
This medicine is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether dexlansoprazole passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Dexlansoprazole is not approved for use by anyone younger than 12 years old.

Call your doctor if your symptoms do not improve, or if they get worse while using dexlansoprazole.
If you use dexlansoprazole for longer than 3 years, you could develop a vitamin B-12 deficiency. Talk to your doctor about how to manage this condition if you develop it.
