The results obtained with intermittent bromocryptine treatment from the fifth day after the beginning of menstruation until the second day after the basal temperature rise, in 14 women with hyperprolactinemic amenorrhea-galactorrhea and in whom menses had previously been induced by continuous treatment, are presented. All women had menses without reappearance of galactorrhea; serum FSH, LH, estradiol, and progesterone followed a normal physiologic trend. Only prolactin rose again in the second phase of the cycle, in which lower levels of progesterone were also found, but without any significant interference in the clinical and hormonal trend. It is stressed that administration of bromocryptine during the first part of the cycle might substitute for continuous administration, thereby reducing drug consumption and hence possible side-effects as well as the cost of treatment.
