Rabeprazole

Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026

Rabeprazole is a proton pump inhibitor used for gastroesophageal reflux disease, erosive esophagitis, Helicobacter pylori combination therapy, duodenal ulcer, and pathologic hypersecretory conditions. Long-term or high-dose use can contribute to hypomagnesemia, vitamin B12 deficiency, reduced non-heme iron absorption, fracture risk, kidney injury, and enteric infection risk.

In short

What the research says.

A quick, data-only summary. The full evidence, dosing, and sources are below.

Rabeprazole is a proton pump inhibitor used for gastroesophageal reflux disease, erosive esophagitis, Helicobacter pylori combination therapy, duodenal ulcer, and pathologic hypersecretory conditions. NutriStack rates the supporting evidence as strong. Common adult dosing is Adults: commonly 20 mg once daily for GERD or erosive esophagitis; 20 mg twice daily as part of H. pylori regimens; higher individualized doses may be used for hypersecretory conditions., though a prescriber sets the actual dose. With long-term use it can deplete magnesium, vitamin b12, iron. This profile indexes 4 sources.

The science

How it works, mechanistically.

Core mechanism

Rabeprazole is an acid-activated benzimidazole prodrug that concentrates in gastric parietal cell canaliculi. After protonation it covalently inhibits the hydrogen-potassium ATPase proton pump, suppressing basal and stimulated gastric acid secretion until new pumps are synthesized. Reduced acidity supports mucosal healing but can impair release and absorption of acid-dependent nutrients and drugs.^2,3

Class

Proton pump inhibitor

Absorption

Best on an empty stomach

Dosing

Dosing & protocol.

Common range

Adults: commonly 20 mg once daily for GERD or erosive esophagitis; 20 mg twice daily as part of H. pylori regimens; higher individualized doses may be used for hypersecretory conditions.

Recommended form

Delayed-release oral tablet or sprinkle capsule, swallowed according to product instructions

Delayed-release tablets are usually taken once daily, often before a meal depending on indication. Do not crush or chew delayed-release products. Acid suppression can reduce absorption of nutrients and drugs that require gastric acidity.

Depletions

What it depletes.

Nutrients this medication can lower over time, and what to replace.

Magnesium

Significant

Long-term PPI therapy can impair intestinal magnesium absorption and cause clinically significant hypomagnesemia.

Replace Magnesium GlycinateMonitor Serum magnesiumOnset Usually after months to years, but earlier in susceptible patients

Vitamin B12

Moderate

Reduced gastric acid can impair release of protein-bound vitamin B12 from food.

Replace Vitamin B12Monitor Serum vitamin B12 with methylmalonic acid when neededOnset Typically after 2 or more years of continuous acid suppression

Iron

Moderate

Reduced gastric acidity can lower solubilization and absorption of non-heme iron.

Replace IronMonitor Ferritin, transferrin saturation, hemoglobinOnset Months to years, especially with low stores or ongoing blood loss

Calcium

Mild

Acid suppression may reduce absorption of some calcium salts and is associated with fracture risk during high-dose or long-term therapy.

Replace CalciumMonitor 25-hydroxyvitamin D, calcium intake assessment, bone density when indicatedOnset Months to years
