Please advice. Should i take it or not?

May be you are facing Laryngopharyngeal reflux, hence Omeprazole is prescribed. OMEPRAZOLE belongs to the class of drugs known as Proton pump inhibitor (PPIs) which reduces the amount of acid your stomach makes. It treats gastroesophageal reflux disease (GERD), stomach ulcer, and Zollinger Ellison syndrome (overproduction of acid due to pancreatic tumour). OMEPRAZOLE helps in reducing the stomach acid by blocking the actions of an enzyme (H+/K+ ATPase or gastric proton pump). This proton pump lies in the cells of the stomach wall responsible for the release of gastric acid secretion damaging tissues in the food pipe, stomach, and duodenum. OMEPRAZOLE prevents the release of stomach acid and relieves symptoms of food pipe lining inflammation (esophagitis), and gastroesophageal reflux disease (GERD), or heartburn.
