Patient: Description of condition (onset, main symptoms, hospital visited, etc.): I have been taking bromocriptine for almost a year, my prolactin was about 32 when it was high, I have a pituitary microadenoma, but it is very small, 5mm. Continue to take bromocriptine (stopping the drug may lead to miscarriage). However, during pregnancy, pituitary microadenomas may increase in size, and some cases have been reported in the literature to be 6-7 times larger, and we have indeed met similar patients in our clinical work, although the percentage is not high. You must be well informed and think twice before deciding! Patient: That means taking the medication during pregnancy will not affect the fetus, right? Fei Zhimin, Department of Neurosurgery, Shanghai Shuguang Hospital East: Long-term clinical follow-up has not found that bromocriptine increases fetal teratogenicity, in other words, taking the medication will not have serious effects on the fetus. Patient: Well, I see, thank you doctor. Then I can take the medication during my pregnancy with peace of mind
