Prevacid vs. Pantoprazole

See how Prevacid and Pantoprazole compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Both Prevacid and pantoprazole are proton pump inhibitors that lower stomach acid, but Prevacid covers more approved uses, including ulcers and H. pylori treatment.

  • Pantoprazole causes higher rates of headache, diarrhea, and nausea in clinical trials compared to Prevacid's most common side effects.

  • Prevacid is sold over-the-counter and in more formulations, while pantoprazole is approved for children as young as 5.

Prevacid vs. Pantoprazole Drug Summary

Prevacid vs. Pantoprazole Indications

Prevacid

Prevacid treats a wide range of acid-related conditions, from duodenal and gastric ulcers to erosive esophagitis and GERD. It is also used with antibiotics to eradicate H. pylori infection and to reduce the risk of NSAID-related stomach ulcers.

  • Duodenal ulcer healing and maintenance

  • Gastric ulcer healing

  • Erosive esophagitis healing and maintenance

Pantoprazole

Pantoprazole is FDA-approved mainly for erosive esophagitis caused by GERD, both for initial healing and for keeping it healed long term. It is also used to control excess stomach acid production in conditions like Zollinger-Ellison syndrome.

  • Erosive esophagitis short-term healing

  • Maintenance of erosive esophagitis healing

  • Zollinger-Ellison syndrome and other hypersecretory conditions

Prevacid vs. Pantoprazole Pros and Cons

Prevacid

Prevacid (lansoprazole) is FDA-approved for the broadest set of acid-related conditions among PPIs, including ulcer healing, H. pylori eradication, and NSAID-ulcer prevention. It comes in capsule, dissolving tablet, and IV forms, and is one of the few PPIs sold over-the-counter. Its list price range runs wider than pantoprazole's.

Pros

  • FDA-approved for a wider range of conditions, including ulcers, H. pylori eradication, and NSAID-related ulcer prevention

  • Available over-the-counter as well as by prescription

  • Comes in capsule, orally disintegrating tablet, and IV forms for flexible administration

  • Approved for long-term maintenance of erosive esophagitis and duodenal ulcers

Cons

  • Not approved for infants under 1 year old

  • Long-term use is specifically linked to an increased risk of fundic gland polyps

  • Can cost significantly more without insurance, roughly $14 to $530 per month, versus $10 to $170 for pantoprazole

Pantoprazole

Pantoprazole covers a narrower set of approved uses, focused mainly on erosive esophagitis and hypersecretory conditions like Zollinger-Ellison syndrome. It offers a simpler once- or twice-daily dosing schedule and is approved for children as young as 5. Its list price tends to run lower, though it lacks an over-the-counter option.

Pros

  • Approved for pediatric use in children as young as 5 years old

  • Simpler once- or twice-daily dosing without Prevacid's multiple condition-specific schedules

  • Typically less expensive without insurance, roughly $10 to $170 per month, versus $14 to $530 for Prevacid

  • Long-established safety and efficacy for erosive esophagitis healing and maintenance

Cons

  • Approved for fewer overall conditions, with no specific indication for ulcer healing or H. pylori eradication

  • Carries an FDA warning for rare but serious skin reactions such as Stevens-Johnson syndrome

  • Not intended for immediate relief of heartburn symptoms
