To understand what NEXIUM does, you need to understand that the lining of your
stomach contains millions of special cells that produce acid via "acid pumps."
When that acid backs up into your
esophagusThe tube that carries food from your throat to your stomach. (generally caused by a relaxation
of your lower esophageal sphincter) you may experience a burning sensation of
heartburn. To reduce the chance of heartburn symptoms like this, NEXIUM turns
off some of those acid pumps. For many people, one NEXIUM pill a day provides
complete 24-hour relief from frequent, persistent heartburn. Your results may
vary.
Prolonged
acid refluxBackflow of stomach acid into the esophagus. Acid reflux frequently happens when the lower esophageal sphincter (LES) relaxes more often than it should and/or at inappropriate times. This allows harsh stomach juices to back up into the esophagus. can, over time, slowly wear away or erode the lining of
your esophagus. For many people, NEXIUM can heal these erosions in 4 to 8
weeks. Your results may vary.
