What Is Omeprazole?

Omeprazole is a medication used to treat stomach and esophagus conditions. Known as a proton pump inhibitor, omeprazole is sold over-the-counter and in stronger doses with a prescription. It is available as an oral tablet and liquid suspension, and medical personnel might administer it as an injection for certain patients. The dose is determined by the severity of the patient's stomach or esophageal issues and by the patient's other medical conditions.
