Read this Medication Guide before you start taking DEXILANT and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or your treatment.
What is the most important information that I should know about DEXILANT?
DEXILANT may help your acid-related symptoms, but you could still have serious stomach problems. Talk with your doctor.
DEXILANT can cause serious side effects, including:
  • A type of kidney problem (acute tubulointerstitial nephritis). Some people who take proton pump inhibitor (PPI) medicines, including DEXILANT, may develop a kidney problem called acute tubulointerstitial nephritis, that can happen at any time during treatment with PPI medicines. Call your doctor right away if you have a decrease in the amount that you urinate or if you have blood in your urine.
  • Diarrhea. DEXILANT may increase your risk of getting severe diarrhea. This diarrhea may be caused by an infection (Clostridium difficile) in your intestines.
    Call your doctor right away if you have watery stool, stomach pain, and fever that does not go away.
  • Bone fractures. People who take multiple daily doses of PPI medicines for a long period of time (a year or longer) may have an increased risk of fractures of the hip, wrist or spine. You should take DEXILANT exactly as prescribed, at the lowest dose possible for your treatment and for the shortest time needed. Talk to your doctor about your risk of bone fracture if you take DEXILANT.
  • Certain types of lupus erythematosus. Lupus erythematosus is an autoimmune disorder (the body's immune cells attack other cells or organs in the body). Some people who take PPI medicines may develop certain types of lupus erythematosus or have worsening of the lupus they already have. Call your doctor right away if you have new or worsening joint pain or a rash on your cheeks or arms that gets worse in the sun.
DEXILANT can have other serious side effects. See "What are the possible side effects of DEXILANT?".
DEXILANT is a prescription medicine called a proton pump inhibitor (PPI). DEXILANT reduces the amount of acid in your stomach.
DEXILANT is used in people 12 years of age and older:
  • for up to 8 weeks to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE)
  • for up to 6 months in adults and up to 16 weeks in children 12 to 17 years of age to continue healing of erosive esophagitis and relief of heartburn
  • for 4 weeks to treat heartburn related to gastroesophageal reflux disease (GERD)
GERD happens when acid from your stomach enters the tube (esophagus) that connects your mouth to your stomach. This may cause a burning feeling in your chest or throat, sour taste or burping.
It is not known if DEXILANT is safe and effective in children under 12 years of age. DEXILANT is not recommended in children under 2 years of age and may harm them.
DEXILANT is not effective for symptoms of GERD in children under 1 year of age.
