Nexium Dosing

The usual starting dose of Nexium for adults experiencing symptoms of gastroesophageal reflux disease (GERD) is 20 mg once a day for four to eight weeks. For children ages 12 to 17 with symptoms of GERD, the recommended Nexium dosage is 20 mg to 40 mg once a day for up to eight weeks. For people infected with Helicobacter pylori, the dose of Nexium prescribed is usually 40 mg once a day, taken in conjunction with other medications for 10 days.

 

Nexium Dosing: An Introduction

The dose of Nexium® (esomeprazole magnesium) prescribed by your healthcare provider may vary depending on a number of factors, including:
 
  • The medical condition you are being treated for
  • Other medical conditions you may have
  • Other medications you may be currently taking.
     
As is always the case, do not adjust your Nexium dosage unless specifically instructed by your healthcare provider to do so.
 

Nexium Dosage for GERD and Erosive Esophagitis

For people with gastroesophageal reflux disease (
 GERD) symptoms, the recommended Nexium dosage is Nexium 20 mg once a day for four to eight weeks. If your GERD is severe enough to cause esophageal erosions (known as erosive esophagitis), the recommended dose is Nexium 20 to 40 mg once daily for four to eight weeks, followed by 20 mg once daily (to prevent the return of erosive esophagitis after healing has occurred).
 
For GERD in children ages 12 to 17, the recommended Nexium dose is 20 mg to 40 mg once a day for up to eight weeks.
 
For GERD in children age 1 to 11 years old, the recommended Nexium dose is 10 mg once daily for up to eight weeks. For erosive esophagitis in children of this age, the dose is the same (10 mg once daily), unless the child weighs 44 pounds or more, in which case the dose is 20 mg daily.
