What are bromocriptine tablets or capsules?
BROMOCRIPTINE (Parlodel®) comes from a group of medicines known as ergot alkaloids. It blocks the release of a hormone called prolactin that affects the menstrual cycle and breast milk production. Bromocriptine is useful in treating menstrual and fertility problems and symptoms caused by cancers (adenomas) that raise prolactin levels in the body. Bromocriptine can be used to treat Parkinson's disease. The drug is also helpful in treating acromegaly (excessive growth hormone). Generic bromocriptine tablets and capsules are available.

What should I watch for while taking bromocriptine?
Visit your prescriber or health care professional for regular checks on your progress.

You may get dizzy or drowsy. Do not drive, use machinery, or do anything that requires mental alertness until you know how bromocriptine affects you. To reduce the risk of dizzy or fainting spells, do not stand or sit up quickly, especially if you are an older patient. Alcohol can make you more dizzy, and increase flushing and rapid heartbeats. Avoid alcoholic drinks. Dizziness is more common after the first dose. Take it before bedtime if possible and be careful getting out of bed.
Avoid exposure to cold. Contact your provider promptly if you experience tingling, burning, or numbness in your hands or feet.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water, will help.
If you are going to have surgery, tell your prescriber or health care professional that you are taking bromocriptine.

What is/are Bromocriptine?
Bromocriptine (INN; trade names Parlodel, Cycloset), an ergoline derivative, is a dopamine agonist that is used in the treatment of pituitary tumors, Parkinson's disease (PD), hyperprolactinaemia, neuroleptic malignant syndrome, and type 2 diabetes.
Most frequent side effects are nausea, orthostatic hypotension, headaches, and vomiting through stimulation of the brainstem vomiting centre. Bromocriptine can cause worsening of liver problems. Vasospasms with serious consequences such as myocardial infarction and stroke that have been reported in connection with the puerperium, appear to be extremely rare events. Peripheral vasospasm (of the fingers or toes) can cause Raynaud's Phenomenon. Bromocriptine use has been anecdotally associated with causing or worsening psychotic symptoms (its mechanism is in opposition of most antipsychotics, whose mechanisms generally block dopamine). Pulmonary fibrosis has been reported when bromocriptine was used in high doses for the treatment of Parkinson's disease.
Amenorrhea, female infertility, galactorrhea, hypogonadism, and acromegaly may all be caused by pituitary problems, such as hyperprolactinaemia, and therefore, these problems may be treated with this drug. Bromocriptine has completely treated gestational macromastia eliminating the need for reduction surgery, in a recent case.Since the late 1980s it has been used, off-label, to reduce the symptoms of cocaine withdrawal. In 2009, bromocriptine mesylate was approved by the FDA for treatment of type 2 diabetes under the trade name Cycloset (VeroScience). It is currently unknown how this drug improves glycemic control, but it has been shown to reduce HbA1c by ~0.5 percentage points.
