Another multicenter RCT evaluated women with PMDD who received levonorgestrel 90 mcg with ethinyl estradiol 20 mcg or placebo daily for 112 days.41 Symptoms were recorded utilizing the DRSP. Significantly more women taking the daily combination hormone (52%) than placebo (40%) had a positive response (≥ 50% improvement in the DRSP 7-day late luteal phase score and Clinical Global Impression of Severity score of ≥ 1 improvement, evaluated at the last “on-therapy” cycle [P = .025]). Twenty-three of 186 patients in the treatment arm dropped out because of adverse effects.

Noncontraceptive estrogen-containing preparations. Hormone therapy preparations containing lower doses of estrogen than seen in OC preparations have also been studied for PMS management. A 2017 Cochrane review of noncontraceptive estrogen-containing preparations found very low-quality evidence to support the effectiveness of continuous estrogen (transdermal patches or subcutaneous implants) plus progestogen.49

Progesterone. The cyclic use of progesterone in the luteal phase has been reviewed as a hormonal treatment for PMS. A 2012 Cochrane review of the efficacy of progesterone for PMS was inconclusive; however, route of administration, dose, and duration differed across studies.42

Another systematic review of 10 trials involving 531 women concluded that progesterone was no better than placebo in the treatment of PMS.43 However, it should be noted that each trial evaluated a different dose of progesterone, and all but 1 of the trials administered progesterone by using the calendar method to predict the beginning of the luteal phase. The only trial to use an objective confirmation of ovulation prior to beginning progesterone therapy did demonstrate significant improvement in premenstrual symptoms.

This 1985 study by Dennerstein et al44 prescribed progesterone for 10 days of each menstrual cycle starting 3 days after ovulation. In each cycle, ovulation was confirmed by determinations of urinary 24-hour pregnanediol and total estrogen concentrations. Progesterone was then prescribed during the objectively identified luteal phase, resulting in significant improvement in symptoms.
