What is bromocriptine? Back to top

The Cycloset brand of bromocriptine is used together with diet and exercise to treat type 2 diabetes. Cycloset is not for treating type 1 diabetes.

The Parlodel brand of bromocriptine is used to treat certain conditions caused by a hormone imbalance in which there is too much prolactin in the blood (hyperprolactinemia). Symptoms include lack of sexual development in adolescents. Women may have missed menstrual periods, loss of interest in sex, hot flashes, infertility, or unexpected breast milk production and leakage from the nipples. Men may have enlarged breasts, decreased libido, decreased facial or body hair, and loss of muscle. Parlodel is also used to treat these disorders when they are caused by brain tumors that can produce prolactin.

Parlodel is sometimes used together with surgery or radiation in treating acromegaly, a condition caused by a pituitary gland tumor that produces too much growth hormone.

Parlodel is also used to treat symptoms of Parkinson's disease, such as stiffness, tremors, muscle spasms, and poor muscle control.

Bromocriptine may also be used for purposes not listed in this medication guide.
