In order to minimise foetal exposure to bromocriptine, it is suggested that patients should use mechanical contraception. Once three regular menstrual cycles have occurred, contraceptive precautions are discontinued. In this way, pregnancy can be suspected as soon as a menstrual period is forty-eight hours overdue. At that time, a serum human chorionic gonadotrophin-b assay should be performed to confirm the pregnancy, and the patient should discontinue bromocriptine therapy. In this way, the foetus is exposed to bromocriptine for a theoretical maximum of sixteen days.
