The effect of dydrogesterone on premenstrual symptoms was investigated in a double-blind, randomized, placebo-controlled study comprising 161 patients from unselected practice material. Dydrogesterone 10 mg twice daily from the 12th day until onset of the following menstrual period was compared with placebo throughout 3 cycles. No clinically relevant effect of dydrogesterone was found. There was an overall therapeutic effect in 52% of the patients on dydrogesterone, and in 44% of the placebo-treated patients. Therapeutic gain ranged between -7 and +23% (95% confidence limits). Type II error risk of failure to detect a therapeutic gain of 20% was 6%. A significant effect of dydrogesterone was found on decreased libido, and statistical significance was nearly achieved for the symptoms irritability and headache. The significant effect on libido can be attributed to mass significance.

Dysmenorrhea means not only uterine pain in the lower abdomen and back, but in many cases headaches, depression, perspiration, nausea, vomiting, and diarrhea, mostly during the first 12-48 hours of menstruation. Primary dysmenorrhea begins at a young age, and some investigators have stated that 50% all of women suffer from dysmenorrhea. No gynecological cure has been found. The socioeconomic consequences are substantial due to absences from school and work. It was previously believed that dysmenorrhea was caused by hormonal imbalance, but there is now evidence that it could be caused by prostaglandins in the menstrual blood. When prostaglandins are administered, the aforementioned side effects of dysmenorrhea are experienced. Since the 1960s, oral contraceptives (OCs) have been administered with success. If for some reason OCs are not advisable, there are very few effective alternatives. Dydrogesterone, a retroprogesterone derivative, does not slow down ovulation, but has to be taken for several weeks of the month just like the pill. Several inhibitors of prostaglandin synthesis are available, but naproxene is the best. It is the longest acting, requiring administration only 2 times/day. It works immediately and can be taken when needed. Because it is used only when needed, there is a minimm of side effects from long-term use. It should not be used by women under 16 years of age. Side effects of all prostaglandin synthesis inhibitors are nausea, vomiting, abdominal pain, and diarrhea. The use of calcium is also advised and warrants further study.

The symptomatology of the premenstrual syndrome is frequently seen in general and gynecological practice. The aim of this study was to examine the therapeutical effect of dydrogesterone (Duphaston) on the typical premenstrual complaints as depression, headache, edema, mastodynia, dysmenorrhea and bleeding irregularities. Oral administration of 20 mg dydrogesterone b.i.d. during the second half of the menstrual cycle could well relieve the complaints mentioned above. Best results of treatment were obtained in cases of dysmenorrhea, bleeding irregularities, depression and edema. In our patients mastodynia was not influenced by dydrogesterone-therapy. As shown by basal body temperature and progesterone in plasma the menstrual cycles remained ovulatory under therapy. The treatment with dydrogesterone was tolerated well in general, blood pressure and body weight were not altered significantly. The majority of patients wished to continue the treatment beyond the period of this study.
