Objective: To discuss the role of a proton pump inhibitor (pantoprazole) as a cause of night sweats in an older person.
Methods: Our case involves a 73 year-old man who experienced night sweats while taking pantoprazole to treat gastroesophageal reflux disease.
Results: Night sweats disappeared ten days after ceasing pantoprazole. They recurred two months later, one week after recommencing pantoprazole.
Conclusion: Proton pump inhibitors are a rare cause of night sweats in older persons.
