The usual starting dose of Nexium for adults is 20 mg once a day for four to eight weeks. For children ages 12 to 17, the recommended amount is 20 mg to 40 mg once a day for up to eight weeks. For people infected with Helicobacter pylori, the recommended dose is usually 40 mg once a day, taken with other medications for 10 days.
The dose of Nexium® (esomeprazole magnesium) your healthcare provider recommends will vary, depending on a number of factors, including:
- The medical condition being treated
- Other medical conditions you may have
- Other medications you may be currently taking.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
For people with gastroesophageal reflux disease (GERD) symptoms, the recommended Nexium dosage is 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 dosage 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 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 Nexium 20 mg daily.
