Documented effects of Sitagliptin on libido
Some medications in DPP-4 inhibitor are designed specifically to affect sexual function; for those, libido changes are expected and central to the indication. Others have libido changes as side effects of altered hormones, mood, energy or autonomic function. According to the prescribing information for Sitagliptin, the documented frequency varies and is listed in the side-effect profile.
Managing libido changes
For unwanted libido suppression, the right response often depends on whether the issue is the medication itself, the underlying condition, fatigue, or relationship factors. Sitagliptin reversibly inhibits DPP-4, the serine protease responsible for rapid degradation of glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). A dose review, a switch within the same class, or addressing other contributors are all reasonable strategies and should be discussed with the prescriber rather than self-managed by stopping Sitagliptin at 25mg, 50mg, 100mg.
