Young patients with hyperprolactinemia should be treated with bromocriptine medication for a period of time before preparing for pregnancy. After passing the medication, the prolactin level should be checked every 4 weeks to determine the minimum effective dose, and the prolactin can be controlled to normal levels within 3 months before starting to prepare for pregnancy, and the medication should be taken until pregnancy. Some doctors believe that the medication should be stopped immediately after pregnancy, but in patients with hyperprolactinemia who stop taking the medication early, spontaneous miscarriage and embryonic abortion will follow, but it is not clear whether this is related to the increase in prolactin level after stopping the medication immediately. The timing of stopping the drug after pregnancy varies, but the safety of bromocriptine in pregnant women can be confirmed.
