Bromocriptine is used for:

Treating Parkinson disease, certain conditions caused by too much prolactin in the blood (eg, excessive or abnormal breast milk production), certain menstrual problems, or abnormally large growth of certain body parts (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 and 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 or developed high blood pressure associated with pregnancy
• you have blood poisoning during pregnancy
• you have recently given birth and have coronary artery disease (chest pain) or other severe heart disease
• you are taking Bromocriptine only for hyperprolactinemia and become pregnant
• you are taking an ergot alkaloid (eg, ergotamine), an HIV protease inhibitor (eg, ritonavir), a ketolide (eg, telithromycin), a macrolide (eg, erythromycin), a nonnucleoside reverse transcriptase (NNRT) inhibitor (eg, efavirenz), or sumatriptan

Contact your doctor or health care provider right away if any of these apply to you.
