Omeprazole can be used to treat gastroesophageal reflux disease, or GERD, by helping to decrease the damage done to the esophagus; it can also be used to treat ulcers as well as Zollinger-Ellison syndrome, according to the National Institutes of Health's MedlinePlus. Omeprazole can be used alone or in conjunction with other medication, depending on the condition and individual needs of the patient.
Prescription omeprazole can be used for more serious gastrointestinal issues, such as GERD, Zollinger-Ellison syndrome or ulcers, through a prescription, but it can also be available over the counter to treat more minor issues, like heartburn, as stated by MedlinePlus.
GERD is a condition in which stomach acid is not properly kept in the stomach and is released back up the esophagus. This condition can lead to serious damage to the esophagus as well as pain associated with heartburn and indigestion. Omeprazole helps the esophagus heal and prevents further damage to the tissues. Zollinger-Ellison syndrome is a medical condition in which the stomach produces too much acid, resulting in gastrointestinal issues. Omeprazole can be used to treat Zollinger-Ellison and the symptoms associated with it. Ulcers that have formed along the stomach or intestinal lining or ulcers that have formed as a result of the H. pylori bacteria can also be treated with omeprazole.
