Bromocriptine (Parlodel) is used to treat symptoms of hyperprolactinemia (high levels of a natural substance called prolactin in the body) including lack of menstrual periods, discharge from the nipples, infertility (difficulty becoming pregnant) and hypogonadism (low levels of certain natural substances needed for normal development and sexual function).

Bromocriptine is in a class of medications called dopamine receptor agonists. It treats hyperprolactinemia by decreasing the amount of prolactin in the body. It treats acromegaly by decreasing the amount of growth hormone in the body. It treats Parkinson's disease by stimulating the nerves that control movement. The way bromocriptine works to treat diabetes is not known.
