Figure 2. Long-term effects of bromocriptine therapy. Prolactin levels in a group of patients on long-term bromocriptine therapy were tested before therapy; after 3 months, 6 months (during which time all patients received bromocriptine 2.5mg three times per day) 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. Reproduced with permission from J Clin Endocrinol Metab 50:1026 1033.
