Why is Dexilant prescribed?

Dexilant is in a class of medications called Proton Pump Inhibitors (PPIs), and is a delayed-release (long-acting) capsule, usually taken once a day. Dexilant is used to treat gastroesophageal reflux disease (GERD), a condition in which stomach acid back flows (refluxes) into the esophagus, causing heartburn and possible injury to the esophagus. Dexilant is also used to treat erosive esophagitis, a condition in which inflammation, swelling, or irritation of the esophagus occurs. Dexilant can also be used to prevent erosive esophagitis from returning in patients who have been treated for this condition.

Special precautions to follow when taking Dexilant

Before taking Dexilant, you should:

  • Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take
  • Tell your doctor and pharmacist if you are allergic to dexlansoprazole, one of the other Proton Pump Inhibitors (Nexium, Prevacid, Prilosec, Protonix, Aciphex), or any other medications

  • Tell your doctor if you have been diagnosed with liver disease, either as a present or past condition
  • Tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking Dexilant, call your doctor
  • If you feel you also need an antacid, ask your doctor to recommend one and to tell you when and how to take it
  • What to do if you forget a dose of Dexilant

    Consult your physician before taking a missed dose. Your doctor will be able to determine if it is safe to do so, or if you should wait until your next scheduled dose. Do not take a double dose to make up for a missed one.
