Dienogest (Dinogest) Dose for Adenomyosis

Dienogest (Dinogest) is taken at 2 mg by mouth once daily for symptomatic adenomyosis. [1]

  • Dose: 2 mg orally once daily. [1]
  • Schedule: taken continuously (no dose escalation is used in the regimen studied). [1]

Supporting Evidence for This Dose in Adenomyosis

  • In a randomized, double-blind, placebo-controlled multicenter trial in symptomatic adenomyosis, patients assigned to dienogest received 2 mg/day orally for 16 weeks. [1]
  • Clinical use of dienogest tablets follows a 1 tablet daily without any break dosing schedule for the 2 mg strength formulation. [2]

Clarification on Product Naming

  • Dinogest is a brand name for dienogest, not dydrogesterone. [2]

Practical Administration Notes

  • Treatment can be started on any day of the natural cycle for the dienogest 2 mg tablet regimen. [2]
