Uses of This Medicine
Bromocriptine belongs to the group of medicines known as ergot alkaloids. Bromocriptine blocks the release of a hormone called prolactin from the pituitary gland. Prolactin affects the menstrual cycle and milk production.
Bromocriptine is used to treat certain menstrual problems (e.g., amenorrhea) in women and stops milk production in some men and women who have abnormal milk leakage. It is also used to treat infertility in both men and women that occurs because the body is making too much prolactin.
This medicine is available only with your doctor’s prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, bromocriptine is used in certain patients with the following medical conditions:
