Scheduled withdrawal bleeding ~90%
Preferred in recently menopausal women

E + P Continuous Long Cycle (Rare)
“Cyclic withdrawal”
Estrogen administered daily
Progesterone co-administered with estrogen for at least 12 to 14 days every other month
Results in 6 scheduled bleeding times per year
Limited safety data: endometrial protection unclear

Results in endometrial atrophy and absence of vaginal bleeding
Initial unpredictable spotting or bleeding which usually resolves within 6-12 months
Drug free period of 1-2 weeks may help stop bleeding
Recommended for women >2 years post-final menstrual period
