Does hyperprolactinemia treatment affect pregnancy and perinatal outcomes?

The aim of this study was to assess obstetric and perinatal outcomes in women with hyperprolactinemia according to the type of treatment indicated, with cabergoline or bromocriptine.

A retrospective cohort study with 464 women diagnosed with hyperprolactinemia was undertaken at the endocrine gynecology outpatient clinic of a tertiary hospital from May 2002 to February 2022. All women diagnosed with hyperprolactinemia who were being treated with dopamine agonists (cabergoline or bromocriptine) and who became pregnant during the follow-up were included. Women whose medical records did not provide data related to pregnancy and delivery were excluded. The women were divided into two groups according to the type of treatment: bromocriptine or cabergoline. Clinical and laboratory characteristics and obstetric and perinatal outcomes, such as complications during pregnancy, type of delivery, and intrapartum complications, were evaluated in both groups.

Of the 464 women evaluated, 72 became pregnant during the follow-up, 66 of them were using dopamine agonists, while 6 were not using medication. The mean age of the women was 28.3±6.8 years. Among the causes of hyperprolactinemia, 48.6% were idiopathic, 45.7% were tumoral, and 3.7% had other causes. Most women with idiopathic hyperprolactinemia used bromocriptine, while those with tumoral hyperprolactinemia used cabergoline (p=0.04). There was no difference in obstetric outcomes according to the type of treatment used. The majority of women did not have any complications during pregnancy (76.3%) or intrapartum (86.8%).

Regardless of the type of previous drug treatment with dopamine agonists, hyperprolactinemia does not alter obstetric outcomes.
