GERD
Erosive esophagitis
Stomach and duodenal ulcers

Frequently asked questions

What is pantoprazole used for?

Pantoprazole reduces stomach acid and treats GERD, erosive esophagitis, stomach ulcers, and Zollinger-Ellison syndrome.

What is the difference between pantoprazole and omeprazole?

Both are PPIs and work similarly. Pantoprazole has fewer drug interactions (particularly with clopidogrel) and is prescription only. Omeprazole is available OTC in lower doses.

Can I take pantoprazole long term?

Long-term use carries risks including low magnesium, B12 deficiency, and bone fractures. Regular review with your doctor is important.

Should I take pantoprazole before or after eating?

Take pantoprazole 30–60 minutes before a meal. It must be taken before eating to effectively block the acid pumps activated by food.

Does pantoprazole cause weight gain?

Pantoprazole itself does not directly cause weight gain. If it effectively treats GERD, you may eat more comfortably which could lead to changes over time.
