INFORMATION ABOUT FEXUPRAZAN
Fexuprazan Uses
Fexuprazan is used in the treatment of erosive esophagitis.
How Fexuprazan works
Fexuprazan is a potassium-competitive acid blocker (P-CAB) that works by directly and reversibly blocking the H⁺/K⁺-ATPase enzyme, also known as the proton pump, in the stomach’s acid-secreting cells. By doing so, it reduces the production of stomach acid at its source, helping to relieve acid-related symptoms and promote healing of the esophagus.

Expert advice for Fexuprazan
  • Take it daily at the same time each day to maintain steady acid control and support healing of the esophagus.
  • Avoid spicy, acidic, or fatty foods, as they can trigger reflux symptoms and slow down healing.
  • Do not lie down immediately after eating; wait for at least 2 to 3 hours to reduce acid reflux.
  • Avoid alcohol and smoking, as both can irritate the esophagus and interfere with treatment.
  • Do not skip doses or stop early, even if symptoms improve. Make sure to complete the full course as advised by your doctor.
  • Inform your doctor about all other medications or supplements you are taking, as Fexuprazan may affect their absorption.
Frequently asked questions for Fexuprazan

It works by blocking the acid pump in the stomach (proton pump), reducing the amount of acid produced, and allowing the esophagus to heal.
Many patients begin to feel relief from symptoms like heartburn within a few days, but full healing of the esophagus may take 4 to 8 weeks.

Some people may experience mild side effects such as nausea, indigestion, headache, or abdominal discomfort. Most of these are temporary and go away on their own.
