Uses of Parlodel

Parlodel is used in:

Mode of action of Parlodel

It works by decreasing the levels of certain hormones released in the body like prolactin.

Bromocriptine helps in lowering down the unusual hike in the levels of the hormones like prolactin and growth hormone but, it is not capable of curing the cause of the hike in production of these hormones.
