What is Omeprazole used for?
Omeprazole is a medication used to treat conditions caused by too much stomach acid. This includes gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome [1]. It works by decreasing the amount of acid produced in the stomach [1].
How does Omeprazole work?
Omeprazole belongs to a class of drugs called proton pump inhibitors (PPIs) [1]. It works by blocking the action of the proton pumps in the stomach lining, which are responsible for producing acid [1]. By inhibiting these pumps, omeprazole effectively reduces stomach acid secretion [1].

What are the common side effects of Omeprazole?
Common side effects associated with omeprazole use can include headache, diarrhea, nausea, vomiting, and abdominal pain [1]. Less common side effects may also occur [1].
What are the alternatives to Omeprazole?
Other proton pump inhibitors are available as alternatives to omeprazole, such as lansoprazole, pantoprazole, rabeprazole, and esomeprazole [3]. Histamine-2 (H2) blockers are another class of medications that can reduce stomach acid and are sometimes used as alternatives or in combination with PPIs [3].

In some countries, lower-strength formulations of omeprazole are available over-the-counter for the short-term treatment of frequent heartburn [1]. Higher strengths and specific indications typically require a prescription from a healthcare professional [1].
