Parlodel lowers prolactin levels. Prolactin is a hormone important for the production of breast milk and for normal fertility in women.
Parlodel 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.
Parlodel is also used to treat Parkinson's disease, which is associated with low levels of dopamine in the brain. Parlodel 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.
How to use
Use Parlodel as directed by your doctor. Check the label on the medicine for exact dosing instructions.
Take Parlodel by mouth with or without food.

Drug Class and Mechanism
Parlodel is a dopamine agonist. It works by blocking the release of prolactin from the pituitary gland and lowering growth hormone levels (in patients with acromegaly). In Parkinson disease, Parlodel works by stimulating dopamine receptors in certain parts of the brain.
