Sitagliptin-induced hiccups: A rare side effect

Background: Hiccups are a normal physiological response, but sometimes they become a cause of social embarrassment. Materials and Methods: A 72-year-old male who is a known case of type II diabetes mellitus for the last 6 years came to our outdoor department with complaints of hiccups. Currently, he was on Glimipride 2 mg daily for the last 6 years and on Sitagliptin 100 mg daily for the last 6 months. Results: On stopping Sitagliptin himself, his hiccups stopped. Conclusion: Hiccups are regarded as a normal behavior and time-limited symptom but if prolonged or intractable, a thorough history and investigation must be done to find out the cause which might lead to serious consequences. Most probably, this is the first case report showing that Sitagliptin is the cause of hiccups.
