[Persisting suppression of hyperprolactinemia after bromcriptine withdrawal].
The 22-years old patient with secondary amenorrhea, galactorrhea and macroprolactinoma of hypophysis was observed. After the therapy with Parlodel, which lasted 34 months, her menstrual cycle became regular and the level of prolactin was normal. The quantity of Parlodel used daily for the normalization of prolactin was 20 mg at the beginning, and only 2,5 mg later on. This quantity was taken intermittently, only until the ovulation. She conceived 5 months after therapy withdrawal. During the pregnancy period, prolactin in serum was not higher then physiological value. The pregnancy did not cause any growth of tumor. After the delivery and the break of lactation, hyperprolactinemia persisted, but only 29,1-34,4% of the value before the beginning of the therapy.
