Omeprazole is a proton pump inhibitor that works by reducing the amount of acid produced in the stomach, as stated by Mayo Clinic. This medication is used to treat health conditions that are caused by elevated levels of stomach acid. Omeprazole is available both through a doctor's prescription and over-the-counter.
This medication is used to treat gastroesophageal reflux disease, gastric and duodenal ulcers and erosive esophagitis. It is also combined with antibiotics to treat ulcers that are linked to a condition caused by Helicobacter pylori bacteria. Omeprazole is used to treat Zollinger-Ellison syndrome, a condition where the stomach produces plenty of acid. A doctor may also prescribe it to treat dyspepsia, a condition that leads to heartburn, belching, indigestion or sour stomach. Additionally, Omeprazole can be used to prevent bleeding in the upper gastrointestinal tract.
Omeprazole is available as a delayed-release capsule, delayed-release tablet, powder and packet, according to Mayo Clinic. Before using the medication, it is important for a person to tell their doctor if they have an allergy to any medications or if they are breastfeeding, pregnant or taking other medications. Dosage is usually different depending on the specific situation of a particular patient.
