Flumedroxone acetate has been assessed in over 1,000 patients for the treatment of migraine, with effectiveness ranging from excellent to less than that of the reference antimigraine drug methysergide. Other progestogens including medroxyprogesterone acetate, lynestrenol, allylestrenol, dydrogesterone, and normethandrone have also been found to be effective for migraine in a high percentage of women.
In accordance with its progestogenic activity, flumedroxone acetate produces menstrual irregularities, namely polymenorrhea, and breast tension as side effects in women.
Flumedroxone acetate is said to have weak or slight progestogenic activity without other hormonal activity, including no estrogenic, antiestrogenic, androgenic, anabolic, or glucocorticoid activity.
