GERD Home > What Is the Right Amount of Nexium for Me?
The recommended starting dose of Nexium to reduce the risk of a stomach ulcer (gastric ulcer) associated with nonsteroidal anti-inflammatory drugs (NSAIDs) is Nexium 20 mg or Nexium 40 mg once a day for up to six months.
Treatment to kill Helicobacter pylori (H. pylori) involves using two other drugs in addition to Nexium. This therapy is called "triple therapy." Triple therapy to kill H. pylori involves taking Nexium 40 mg once a day, plus amoxicillin 1000 mg (twice daily) and clarithromycin 500 mg (twice daily). All three medications are taken for 10 days.
