Some of the common uses of this medicine include: Gastroesophageal Reflux Disease (GERD): Pantoprazole is commonly used to treat GERD, a condition that causes acid reflux, heartburn, and other symptoms by allowing stomach acid to flow back into the esophagus. Peptic Ulcer Disease: Pantoprazole may also be used to treat peptic ulcer disease, a condition that causes open sores in the lining of the stomach or small intestine, often caused by infection with the bacteria Helicobacter pylori. Zollinger-Ellison Syndrome: Pantoprazole may be used to treat Zollinger-Ellison Syndrome, a rare condition that causes the stomach to produce too much acid. Prevention of NSAID-Induced Ulcers: Pantoprazole may be used to prevent ulcers that are caused by the use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, or naproxen. It is important to note that pantoprazole should only be used under the guidance of a healthcare provider. If you are experiencing symptoms of GERD, peptic ulcer disease, or any other gastrointestinal condition, you should consult with your doctor to determine the appropriate treatment for your condition.
