Antibiotics are not typically used to treat pancreatitis, as this is an inflammation of the pancreas that is usually caused by gallstones or excessive alcohol consumption. Instead, treatment for pancreatitis focuses on reducing pain and inflammation and preventing complications. This may include pain medications, fluids, and nutrition support. Surgery may also be needed to remove gallstones or to drain fluid from the pancreas. In some cases, antibiotics may be prescribed, such as for an infection that may arise due to the condition. In such cases, antibiotics that are used to treat pancreatitis may include ampicillin, cefuroxime, or metronidazole.
