What is Pariet?

Pariet is a brand medication that contains Rabeprazole, which belongs to a class of Proton pump inhibitors. It works by blocking the proton pumps to inhibit the secretion of gastric acid in the stomach. It is therefore used for Gastroesophageal Reflux Disease (GERD) and peptic ulcer. It can also be used for prevention of gastric ulcer for patients taking Nonsteroidal anti-inflammatory drugs (NSAIDs) that cause stomach bleeding.

How to use it?

Pariet is available as tablets. If you are using it for duodenal ulcers, take it after a meal. If you are using it for H. pylori-associated peptic ulcer, take it with breakfast and dinner.

For GERD above 12 years of age,
The starting dose is 20 mg once daily for 4-8 weeks. The maintenance dose is 10-20 mg once daily depending on body response. For those without symptoms, take 10-20 mg once daily for 4 weeks. For maintenance, take 10 mg once daily as needed.

For Peptic ulcers in adults,
Take 20 mg once daily for 4-12 weeks.
