STALLDECKER, G. et al. Retrospective Study of any potencial Adverse Effects of Cabergoline on Pregnancy and Embryofetal Development. Rev. argent. endocrinol. metab. [online]. 2010, vol.47, n.3, pp.25-29. ISSN 1851-3034.

Objectives: To assess the rate of any potential adverse effects on pregnancy and embryo-fetal development in women who became pregnant under treatment with cabergoline (CAB). To follow up medical data of children who were born from mothers exposed to Cab in early weeks of gestation. Material and methods: Observational, retrospective and multicenter study on 86 pregnancies in 78 women with idiopathic or tumoral hyperprolactinemia. All patients were under Cab at conception. The average age was 29 (range: 20-45). Pituitary images at diagnosis showed 44 microadenomas, 27 macroadenomas and 7 were normal. Serum PRL at baseline was between 30 and 1429 ng/ml. Duration of therapy before pregnancy ranged from 1 to 120 months. Maternal and fetal exposure to cabergoline and doses ranged from 0.125 to 4 mg/week. The mean serum PRL level under which patients achieved pregnancy was 17 ng/ml. Fetal exposure ranged from 3 to 27 weeks; 96.39% of patients received CAB during the first trimester of pregnancy and 3.61% until the second one. Results: No significant complications during pregnancy were found. Seven women (8.1%) had spontaneous abortions. Term deliveries were recorded in 63/69, preterm in six (8.8%), none of them with low weight for gestational age. Neonatal abnormalities were observed in 3 (5.2%): 1 major (Down syndrome) and 2 minor malformations (umbilical and inguinal hernia). Two out of 42, developed abnormalities during the follow- up, one of them was a refractory epilepsy during the second month of life, the other presented a Pervasive Developmental Disorder diagnosed in the third year of life. Conclusion: No significantly higher frequency of complications was found in pregnancies and/or offspring exposed to CAB than in normal population. Larger series of patients are needed to asses the safety.
