Nexium vs. Pantoprazole
See how Nexium and Pantoprazole compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Nexium and pantoprazole are both proton pump inhibitors that reduce stomach acid to heal erosive esophagitis and relieve GERD symptoms, though each carries different additional approvals.
Nexium has a broader set of FDA-approved uses, including NSAID-ulcer prevention and H. pylori treatment, while pantoprazole is approved for younger children in tablet form.
Generic pantoprazole tablets are usually far less expensive than brand-name Nexium capsules, which can matter for people taking a PPI long term.
Nexium vs. Pantoprazole Drug Summary
Nexium
Nexium (esomeprazole magnesium) is a proton pump inhibitor that reduces stomach acid to heal erosive esophagitis and relieve GERD symptoms. It also lowers NSAID-ulcer risk and, combined with antibiotics, helps eradicate H. pylori infection. It comes as a delayed-release capsule, oral suspension, or IV injection taken once or twice daily.
Pantoprazole
Pantoprazole (pantoprazole sodium) is a proton pump inhibitor used to heal erosive esophagitis caused by GERD and to manage conditions that cause excess stomach acid, such as Zollinger-Ellison syndrome. It is taken as a delayed-release tablet, oral suspension, or IV injection, usually once or twice daily.

Nexium vs. Pantoprazole Indications
Nexium
Nexium is FDA-approved to heal and maintain healing of erosive esophagitis, treat short-term heartburn from GERD, and reduce the risk of NSAID-related stomach ulcers. It is also approved, with antibiotics, to eradicate H. pylori and to manage rare acid-hypersecretion disorders like Zollinger-Ellison syndrome. Pediatric approval extends from infants as young as 1 month to teens 12-17.
Healing of erosive esophagitis in adults and teens 12-17
Short-term treatment of heartburn and GERD symptoms
Risk reduction of NSAID-associated stomach ulcers
H. pylori eradication combined with antibiotics
Pantoprazole
Pantoprazole is FDA-approved to heal erosive esophagitis caused by GERD and to maintain that healing over time. It also treats rare acid-hypersecretion disorders such as Zollinger-Ellison syndrome, but it is not approved for immediate relief of heartburn symptoms. Pediatric approval covers children 5 years and older for erosive esophagitis.

Nexium vs. Pantoprazole Pros and Cons
Nexium
Nexium has one of the broadest FDA-approval lists among PPIs, covering ulcer prevention, H. pylori treatment, and use in infants. It is also sold over the counter for short-term heartburn, which some patients find convenient. The tradeoff is a higher typical cost than generic PPI options.
Pros
Approved for NSAID-ulcer prevention and H. pylori eradication, unlike pantoprazole
Approved for infants as young as 1 month with erosive esophagitis
Available over the counter for short-term heartburn relief
Cons
Costs more than generic pantoprazole, roughly $160 to $280 per month without insurance
Not approved for immediate GERD symptom relief in infants under 1 year
Only available as a capsule or oral suspension, not a standard tablet
Pantoprazole
Pantoprazole covers the core PPI uses for erosive esophagitis and acid-hypersecretion disorders, with FDA approval down to age 5. As a widely available generic, it tends to cost much less than brand-name alternatives. It does not carry approvals for NSAID-ulcer prevention, H. pylori treatment, or immediate heartburn relief that Nexium has.
Pros
Available as a low-cost generic tablet, often $10 to $170 per month without insurance
Approved for children as young as 5 in a standard tablet form
Comes as a standard tablet, which some people find easier to swallow than a capsule
Cons
Higher reported rates of headache, diarrhea, nausea, and abdominal pain in trials
Not approved for NSAID-ulcer prevention or H. pylori eradication
Not approved for immediate relief of heartburn symptoms
