Compare Protonix vs. Aciphex

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Pantoprazole (Protonix) and Rabeprazole (Aciphex) are both proton pump inhibitors (PPIs) used to treat conditions involving too much stomach acid, such as GERD. Pantoprazole is available in both oral and intravenous forms, while Rabeprazole is only available orally. Pantoprazole is used for both adults and children aged 5 years and older, whereas Rabeprazole is prescribed for adults and children aged 12 years and older. Pantoprazole is typically taken once daily, but can be taken twice daily for certain conditions, while Rabeprazole is usually taken once daily, with specific dosing for different conditions. Common side effects of Pantoprazole include headache and diarrhea, whereas Rabeprazole may cause constipation and passing gas. Both medications have serious warnings for long-term use, such as the risk of bone fractures and kidney problems. However, Rabeprazole is also used to lower the risk of duodenal ulcers caused by *H. pylori* infection, which is not an indication for Pantoprazole.
