Protonix vs. Aciphex

See how Protonix and Aciphex compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Protonix and Aciphex are both proton pump inhibitors that heal and maintain healing of GERD-related esophagus damage, but neither works fast enough for on-the-spot heartburn relief.

  • Protonix comes as a tablet, oral suspension, or IV injection, while Aciphex is only available as a delayed-release tablet.

  • Aciphex has a broader label for symptomatic GERD in ages 12 and up plus H. pylori eradication, while Protonix typically costs far less without insurance.

Protonix vs. Aciphex Drug Summary

Aciphex (rabeprazole) is a proton pump inhibitor used to heal erosive or ulcerative GERD, maintain that healing, and treat symptomatic GERD in people 12 and older. It also treats duodenal ulcers, helps eradicate H. pylori infection alongside antibiotics, and manages hypersecretory conditions like Zollinger-Ellison syndrome. It is only available as a delayed-release tablet.
