High levels of prolactin (PRL) may cause luteal insufficiency and lead to miscarriage. Therefore, doctors usually treat patients with hyperprolactinemia with different doses of “bromocriptine” depending on the level of prolactin. Generally, doctors recommend stopping the medication after 50-60 days of pregnancy, when the primitive heartbeat of the embryo is visible on ultrasound. How to stop the medication? The dosage should be reduced slowly, whether you were taking 1 or 2 or half a tablet, gradually over a certain period of time under the guidance of your doctor, while monitoring the blood levels of prolactin for appropriateness, until the drug is completely discontinued. Many patients ask, “Why do I need to do this?” The reason is actually very simple. When braking in an emergency, the inertia will make the car rush forward some more before stopping, while a prepared and slow braking will stop the car very steadily in its intended position. During early pregnancy, what we want is a stable level of lactogen in the blood, not a high or low level, and not an emergency brake when we stop the medication – that is, what our doctors call a rebound in lactogen levels when we stop the medication. Again: bromocriptine has no significant toxic effects on the fetus and does not cause fetal malformations, so it should be taken throughout pregnancy if needed. Discontinuation of the drug is only when the doctor considers that the prolactin level is stable and within the permissible range.
