Bromocriptine belongs to the group of medicines known as ergot alkaloids. Bromocriptine blocks release of a hormone called prolactin from the pituitary gland. Prolactin affects the menstrual cycle and milk production. Bromocriptine is used to treat certain menstrual problems or to stop milk production in some women or men who have abnormal milk leakage. It is also used to treat infertility in both men and women that occurs because the body made too much prolactin.
Bromocriptine is also used to treat some people who have Parkinson's disease. It works by stimulating certain parts of the brain and nervous system that are involved in this disease.
Bromocriptine is also used to treat acromegaly (overproduction of growth hormone) and pituitary prolactinomas (tumors of the pituitary gland).
Bromocriptine is also used together with proper diet and exercise to treat high blood sugar levels in patients with type 2 diabetes.
Bromocriptine may also be used for other conditions as determined by your doctor.
This medicine is available only with your doctor's prescription.

It is important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.
It is very important to follow carefully any instructions from your health care team about:
This medicine may cause some people to become drowsy, dizzy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert.
Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position suddenly. These symptoms are more likely to occur when you begin taking this medicine, or when the dose is increased.
Too much bromocriptine can cause low blood sugar (hypoglycemia) when it is used under certain conditions. Symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people may feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly and call someone on your health care team right away when you need advice.
Symptoms of hypoglycemia (low blood sugar) include anxiety; behavior change similar to being drunk; blurred vision; cold sweats; confusion; cool, pale skin; difficulty in thinking; drowsiness; excessive hunger; fast heartbeat; headache (continuing); nausea; nervousness; nightmares; restless sleep; shakiness; slurred speech; or unusual tiredness or weakness.
If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes; or drink fruit juice, non-diet soft drink, or sugar dissolved in water. Also, check your blood for low blood sugar. Glucagon is used in emergency situations when severe symptoms such as seizures (convulsions) or unconsciousness occur. Have a glucagon kit available, along with a syringe or needle, and know how to use it. Members of your household also should know how to use it.
High blood sugar may occur if you do not exercise as much as usual, have a fever or infection, do not take enough or skip a dose of your diabetes medicine, or overeat or do not follow your meal plan.
If symptoms of high blood sugar occur, check your sugar level and then call your doctor for instructions.
Dizziness is more likely to occur after the first dose of bromocriptine. Taking the first dose at bedtime or when you are able to lie down may lessen problems. It may also be helpful if you get up slowly from a lying or sitting position. Your doctor may also recommend that you take the first dose vaginally.
Bromocriptine may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
It may take several weeks for bromocriptine to work. Do not stop taking this medicine or reduce the amount you are taking without first checking with your doctor.
Drinking alcohol while you are taking bromocriptine may cause you to have a certain reaction. Avoid alcoholic beverages until you have discussed this with your doctor. Some of the symptoms you may have if you drink any alcohol while you are taking this medicine are blurred vision, chest pain, confusion, fast or pounding heartbeat, flushing or redness of the face, nausea, severe weakness, sweating, throbbing headache, or vomiting.
