Prolactin levels in a group of patients on long-term bromocriptine therapy were tested before therapy; after three months, six months, and one year of treatment (during which time all patients received bromocriptine 2.5mg three times per day); and two months after cessation of treatment. In all cases, prolactin remained suppressed throughout the year, and in most cases, prolactin levels were held within the normal range. Gonadal function was restored, even in patients whose prolactin levels did not return to normal
