Generic Name: bromocriptine (BROE-moe-KRIP-teen)
Brand Name: Parlodel
Bromocriptine is used for:
Treating Parkinson disease. It is used to treat certain conditions (eg, excessive or abnormal breast milk production, certain menstrual problems) caused by too much prolactin in the blood (hyperprolactinemia). It may also be used to treat certain tumors that make too much prolactin. It is also used to treat a condition where your body makes too much growth hormone (acromegaly). It may also be used for other conditions as determined by your doctor.
Bromocriptine is a dopamine agonist. It works by blocking the release of prolactin from the pituitary gland. It also works by lowering growth hormone levels in patients with acromegaly. In Parkinson disease, bromocriptine works by stimulating dopamine receptors in certain parts of the brain.
Do NOT use bromocriptine if:
- you are allergic to any ingredient in bromocriptine or to ergot alkaloids
- you are breast-feeding
- you have uncontrolled high blood pressure
- you are taking bromocriptine only to treat hyperprolactinemia and you become pregnant
- you have a rare hereditary problem of galactose intolerance, severe lactase deficiency, or glucose-galactose malabsorption
- you are taking an azole antifungal (eg, ketoconazole, miconazole), certain medicines used for migraines ("triptans," such as eletriptan or sumatriptan), efavirenz, an ergot alkaloid (eg, ergotamine), a macrolide antibiotic (eg, erythromycin), a protease inhibitor (eg, boceprevir, ritonavir), or telithromycin
Contact your doctor or health care provider right away if any of these apply to you.
