Context: The current survey study investigated the recurrence rate of hyperprolactinemia after cabergoline (CAB)-induced pregnancy and after lactation as well as safety of CAB exposure during early gestation. Patients and Methods: From 1997–2008, 143 pregnancies were recorded in 91 patients with hyperprolactinemia (age 30.4 ± 4.7 yr, 76 microadenomas, 10 macroadenomas, and five nontumoral hyperprolactinemia). CAB therapy was discontinued within wk 6 of gestation in all. Pregnancies were monitored until delivery or termination, during and after lactation, twice yearly up to 60 months. The incidence of abortions, premature delivery, and fetal malformations was also analyzed. Results: Pregnancies resulted in 13 (9.1%) spontaneous abortions and 126 (88.1%) live births. No neonatal malformations and/or abnormalities were recorded. In 29 of 91 patients (three with macroadenomas), treatment with CAB had to be restarted within 6 months after lactation because of hyperprolactinemia recurrence, whereas in 68% of cases, no additional therapy was required up to 60 months. No tumor mass enlargement was observed. All patients but three were breastfeeding, 35 (38.5%) for less than 2 months and 56 (61.5%) for 2–6 months. Three months after cessation of lactation and 60 months after pregnancy, no difference in prolactin levels was found between patients nursing for less than 2 months and 2–6 months. Conclusions: Fetal exposure to CAB at conception does not induce any increased risk of miscarriage or malformations. Pregnancy is associated with normalization of prolactin levels in 68% of patients. Breastfeeding does not increase the recurrence rate of hyperprolactinemia. - See more at: http://press.endocrine.org/doi/10.1210/jc.2012-3039?url_ver=Z39.88-2003&rfr_id=ori%3Arid%3Acrossref.org&rfr_dat=cr_pub%3Dpubmed&#sthash.2XbWODQS.dpuf
