This is a prescription medicine for treating acid reflux. Omeprazole is a proton pump inhibitor or (PPI) which reduces acid production in the stomach. This medicine is available in 10mg, 20mg and 40mg capsules to be taken once per day.


Omeprazole is a prescription medication recommended for reducing the production of acid in your stomach. Omeprazole falls in the category of proton pump inhibitor medications. This medicine is a helpful remedy for those suffering from heartburn, acid reflux, or indigestion. 

Excessive stomach acid production can damage the mucous lining of the stomach resulting in stomach ulcers and inflammation. Proton pump inhibitors such as Omeprazole are useful in preventing this kind of damage. 

Omeprazole is an effective medication for reducing the amount of stomach acid produced in the body. It is used for the treatment of gastroesophageal reflux disease (GORD) in adults and children. It helps reduce acid reflux, heartburn and indigestion caused by excessive production of stomach acid. 

Omeprazole is also prescribed to those suffering from ulcers in the stomach or the upper part of the intestine. 

Omeprazole is a proton pump inhibitor that acts upon the acid-producing cells of the stomach lining. This medication stops ulcers from forming and helps the stomach lining to heal if there is damage due to excessive stomach acid production. 

Cells found in the lining of the stomach produce stomach acid with the help of proton pumps. The stomach acid function is to help digestion and eliminate any bacteria that may be present in the food we eat. However, excess stomach acid production may cause heartburn, acid reflux, indigestion, or gastroesophageal reflux disease. If the condition is allowed to worsen, it may result in ulcers or damage to the oesophagus and stomach lining. 

Omeprazole is a proton pump inhibitor medicine. It inhibits the stomach lining cells from producing excessive stomach acid to relieve indigestion, acid reflux, and heartburn. In case of an ulcer or any damage to the digestive organs due to acidity, Omeprazole helps complete the healing faster.  

Omeprazole is an effective medication for relief in gastroesophageal reflux and related conditions. There are multiple benefits of taking Omeprazole,some of them are listed below –  

  • Omeprazole prevents excessive stomach acid production to reduce the symptoms of heartburn, acid reflux, and indigestion. 

  • This medication acts quickly to offer relief from acidity related discomfort. 

  • Omeprazole also facilitates quick healing of ulcers in the stomach and upper intestines.  

  • Omeprazole is usually prescribed alongside NSAIDs or painkiller medications to prevent any gastric irritation as a result of NSAIDs. 

  • Gastroesophageal Reflux Disease (GORD) can be a debilitating condition that can make it difficult for you to go about your daily activities. Omeprazole is an effective medication to treat GORD and allow you to continue your work as usual.
