Common questions about rabeprazole

Below you’ll find answers to a few commonly asked questions about rabeprazole.

Is rabeprazole similar to omeprazole or pantoprazole?

Yes, rabeprazole, omeprazole, and pantoprazole are all proton pump inhibitors. However, they are not approved to treat the same gastrointestinal conditions.

Rabeprazole is used to treat the following in adults and children ages 12 years and older:

• gastroesophageal reflux disease (GERD) is a condition where stomach contents, including acid, flow back from your stomach into your mouth

Rabeprazole is also approved to treat the following in adults:

• damage caused by GERD, such as an inflamed or irritated esophagus
• intestinal ulcers (sores in the lining of the intestines)
• conditions where the stomach makes too much acid, such as Zollinger-Ellison Syndrome

Rabeprazole also helps reduce the chance of getting intestinal ulcers due to Helicobacter pylori (a bacterial infection in the stomach).

Omeprazole is approved to treat:

• stomach and intestinal ulcers in adults
• GERD and esophageal damage from GERD in children ages 2 years and older
• conditions where the stomach makes too much acid in adults

Like rabeprazole, omeprazole also helps reduce the risk of getting intestinal ulcers due to H. pylori in adults.

Pantoprazole is approved to treat:

• esophageal damage from GERD and other conditions that cause the stomach to make too much acid
• esophageal damage from GERD in children ages 5 years and older

If you have questions about rabeprazole, omeprazole, and pantoprazole, please talk with your doctor or pharmacist.

How does rabeprazole work? And how long does it take to start working?

Rabeprazole works by preventing certain cells in the lining of the stomach from pumping out too much stomach acid. It can start working in as little as 1 hour. But it may take 2–3 days to feel the full effects of the medication.

If you’d like to know more about how rabeprazole works, talk with your doctor or pharmacist.

Uses of rabeprazole

The Food and Drug Administration (FDA) approves prescription drugs such as rabeprazole for certain conditions. Approved uses for rabeprazole are described below.

Use for certain gastrointestinal conditions

Doctors may prescribe rabeprazole delayed-release oral tablet for treating certain gastrointestinal conditions.“Delayed release” means the drug is released into your body slowly over time. It’s used for this purpose in adults and children ages 12 years and older. It’s usually prescribed as a short-term treatment.

Rabeprazole is used to treat conditions that are caused by too much stomach acid. These include:

• gastroesophageal reflux disease (GERD) in adults and children ages 12 years or older
• damage caused by GERD, such as an inflamed or irritated esophagus in adults
• intestinal ulcers (sores in the lining of the intestines) in adults
• conditions where the stomach makes too much acid, such as Zollinger-Ellison Syndrome, in adults

With too much stomach acid, damage may occur in parts of the gastrointestinal tract. This includes the stomach, esophagus, and small intestine. Too much acid can cause ulcers (painful sores) in your stomach and intestinal lining. Excess stomach acid can also lead to heartburn.

Rabeprazole also helps reduce the chance of getting intestinal ulcers due to H. pylori (a bacterial infection in the stomach) in adults.

With H. pylori, a bacteria can damage your gastrointestinal tract. Symptoms may include burning or dull stomach pain, bloating, nausea, burping, decreased appetite, and more.

Rabeprazole is prescribed together with antibiotics, such as amoxicillin and clarithromycin, to treat H. pylori infections.
