Terminal elimination half-life: 12-15 hours in healthy adults; clinically relevant for once-daily dosing.
Norethynodrel: 5-10 hours; mestranol: 2-5 hours (metabolized to ethinyl estradiol, half-life 10-20 hours). Steady-state reached in 5-7 days.
Renal excretion of unchanged drug: 60-70%; fecal/biliary elimination: 20-30%; hepatic metabolism accounts for <10%.
