Omeprazole 20mg, branded as Mepra-J, is used to treat conditions related to excessive stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. As a proton pump inhibitor (PPI), it works by reducing the production of stomach acid.

The usual dosage for Omeprazole 20mg is one tablet taken once daily, before a meal, for a duration typically ranging from 7 to 14 days, depending on the specific condition being treated and your healthcare provider’s recommendations. Swallow the tablet whole with a glass of water, and do not chew or crush it.

Common side effects may include headache, nausea, diarrhea, constipation, and stomach pain. More serious side effects are less common but can include severe allergic reactions, liver issues, or long-term risks such as bone fractures. If you experience severe symptoms like persistent abdominal pain, signs of an allergic reaction, or unusual fatigue, contact your healthcare provider promptly.
