Bromocriptine is used alone or with other medications (such as levodopa) to treat Parkinson's disease. It can improve your ability to move and can decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. It may also decrease the number of episodes of not being able to move ("on-off syndrome").
Bromocriptine is also used to treat high levels of a certain hormone made by the body (prolactin). High levels of prolactin may cause problems such as unwanted breast milk, missed/stopped periods, difficulty becoming pregnant, decreased sperm production, and decreased sexual ability. Bromocriptine may be used to treat a type of tumor which causes the high levels of prolactin (prolactin-secreting adenomas). It can help to reduce the tumor size. Bromocriptine is not recommended for stopping unwanted breast milk after pregnancy, miscarriage, or abortion because of possible serious side effects (such as high blood pressure, seizure, heart attack, stroke).
Bromocriptine is an ergot medication that works by acting like a certain natural substance (dopamine) in the brain. It also prevents the release of certain hormones (growth hormone, prolactin). Bromocriptine can lower these hormone levels, but it does not cure the causes of the increased levels.
Take this medication by mouth with food as directed by your doctor, usually 1 or 2 times daily. The dosage is based on your medical condition and response to treatment. For the treatment of acromegaly, the dosage is also based on the growth hormone levels. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.
Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Also, you may experience symptoms such as fever, muscle stiffness, and confusion. To prevent these symptoms while you are stopping treatment with this drug, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details.

Some people taking bromocriptine have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with bromocriptine even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
This medication may increase or decrease your blood pressure. Monitor your blood pressure as directed by your doctor. A decrease in blood pressure usually occurs when you are first starting the medication, when your dose is increased, or when you get up suddenly. This effect can cause dizziness, lightheadedness, and fainting. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
