Teneligliptin-induced hair loss: A case report.

Diabetes mellitus (DM) refers to a group of common metabolic disorders that share the common phenotype of hyperglycemia secondary to various pathophysiologic mechanisms that include reduced insulin secretion, decreased glucose utilization, and increased glucose production. Individuals suffering from Type 2 DM (T2DM) tend to be at a higher risk for the development of both micro as well as macrovascular complications. Management strategy includes an armamentarium of drugs and lifestyle modifications. 35 years old male diagnosed with T2DM was started on a fixed-dose combination of 20 mg Teneligliptin and 1 g metformin once daily. After consuming this dose for a month, he observed no reduction in his blood sugar levels and consequently escalated the dose to twice daily without any consultation or supervision. Subsequently, on next visit OPD his blood sugar was controlled, however, he complained of hair loss from the scalp. This complaint was resolved with the discontinuation of Teneligliptin.
