What to watch

  • Mounjaro price reductions, smaller-dose launches or broader insurance/employer reimbursement.
  • Novo Nordisk and domestic GLP-1 competitor launches, shortages or capacity expansions.
  • Prescription growth for obesity versus type-2 diabetes indications.
  • Organized pharmacy cold-chain investment and same-day injectable delivery coverage.
  • Sales declines or discounting in DPP-4, SGLT2, sulfonylurea and other oral diabetes therapy segments.
  • Regulatory action on obesity prescribing, online dispensing or counterfeit injectable products.
  • Build GLP-1 patient journeys spanning prescription fulfilment, cold-chain delivery, refill reminders and clinician-linked adherence support.
  • Bundle diabetes and weight-management baskets with protein nutrition, glucose monitoring, diagnostics and dietitian services.
  • Segment inventory by metro, affluence and specialist-prescriber density; avoid broad-chain stocking assumptions.
  • Prepare substitution and counseling protocols for adverse effects, discontinuation and supply interruptions.
  • Track oral diabetes-brand exposure and reallocate pharmacy merchandising toward injectable-support categories.
