[Studies on the modification of puerperal lactation using methylergobrevin]

During the first 6 days after delivery the daily amount of mild secretion was measured in 300 nursing puerperae who had been treated with 0,2 mg of Methylergobrevin per day in combination with 100 IU Oxytocin. The milk let-down was compared with that of 300 untreated puerperae nursing under the same conditions. A significantly smaller milk let-down was found in treated old primiparae over 30 years, multiparae between 19-30 years and puerperae after premature delivery. In puerperae desiring to nurse their babies the routine post-partum treatment with Methylergobrevin should always be combined with Oxytocin. In women who had a premature delivery and in old primiparae a postpartum treatment with Methylergobrevin should be avoided.
