Methodology
We calculated the annual share of prescription fills by gender for each estrogen patch using a representative sample of U.S. prescription fills from January 1, 2020, through September 30, 2026. Estrogen patches included: Alora, Climara, Dotti, Estraderm, Estradiol, Lyllana, Menostar, Minivelle, and Vivelle-Dot. Fills with unknown gender were removed from gender analyses.
