The FDA approved Viatris' Gwyn Lo, a once-weekly low-dose estrogen (20 mcg) contraceptive patch, based on phase 3 LUMINOUS data showing a Pearl Index of 4.14 pregnancies per 100 woman-years and strong adhesion (98.7% intact). It's approved for women with BMI under 30; common side effects included application-site irritation and intercycle bleeding. Available later in 2026.
