Pantoprazole is a medication commonly used to treat conditions related to excess stomach acid, such as gastroesophageal reflux disease (GERD), Zollinger-Ellison syndrome, and erosive esophagitis. It belongs to a class of drugs known as proton pump inhibitors (PPIs), which work by reducing the amount of acid produced in the stomach.

Typically, pantoprazole is taken orally in the form of tablets or granules, and it's usually prescribed by a healthcare provider. The dosage and duration of treatment depend on the specific condition being treated and the patient's response to the medication.

It's important to follow the prescribed instructions when taking pantoprazole and to discuss any potential side effects or interactions with other medications with a healthcare professional. Common side effects may include headache, diarrhea, nausea, and abdominal pain, but more serious side effects should be reported to a doctor immediately.
