Comment:

• Addition of progestogen is not recommended in women without a uterus who did not have endometriosis.
• A progestogen should be added for at least 12 to 14 days every month (28-day cycle) in women with a uterus (or in endometriosis when endometrial foci are present despite hysterectomy).
• Start therapy any time in women with amenorrhea.
• Start therapy on the first day of bleeding in women who are menstruating.

Comments:

Usual Adult Dose for Menstrual Disorders

20 to 50 mcg orally once a day from day 5 to day 25 of each cycle

Comments:
