What is bromocriptine?

Bromocriptine lowers prolactin (PRO lak tin) levels. Prolactin is a hormone important for the production of breast milk and for normal fertility in women. Bromocriptine also has effects similar to a chemical called dopamine (DOE pa meen) that occurs naturally in the body.

Bromocriptine is used to treat disorders such as amenorrhea (lack of a menstrual period), persistent breast milk production, infertility, and other conditions associated with high prolactin levels caused by prolactin-secreting tumors in women and in men.

In addition, bromocriptine reduces growth hormone levels. This is useful in treating acromegaly, a condition that involves excessive growth.

Bromocriptine is also used to treat Parkinson's disease, which is associated with low levels of dopamine in the brain. Bromocriptine has effects similar to those of dopamine, which makes it effective in the treatment of the stiffness, tremors, spasms, and poor muscle control associated with Parkinson's disease.

Bromocriptine may also be used for purposes other than those listed in this medication guide.
