Background

A member being treated for type 2 diabetes had activeprescriptions for both a GLP-1 receptor agonist and a DPP-4 inhibitor. Bothmedication classes act through the incretin pathway. Current diabetes treatmentguidance does not recommend using them together because adding a DPP-4inhibitor to GLP-1 therapy doesn’t provide meaningful additional glucoselowering. The overlap can add unnecessary medication cost, treatment burden andpotential side effects without a clear clinical benefit.

What we did

HyperCare flagged the duplicate therapy duringpoint-of-sale review and PharmPix’s clinical team contacted the prescriber toconfirm the intended treatment plan. The team shared clinical guidancesupporting discontinuation of the DPP-4 inhibitor when a GLP-1 receptor agonistis being used, while recognizing that the final treatment decision remains withthe prescriber and patient.

The impact

  • Identified     therapy overlap before dispensing
  • Supported     guideline-aligned diabetes treatment
  • Helped     avoid unnecessary medication cost and treatment burden
  • Reinforced     clinically appropriate prescribing at the point of sale

 

Clinical protection happens at the pointdecisions are made. PharmPix helps identify potential medicationrisks and brings clinical protection to the moments that matter.
