What special precautions should I follow?

• During clinical trials, dizziness, drowsiness, faintness, fainting, and syncope have been reported early in the course of bromocriptine therapy.
• Bromocriptine has been associated with somnolence, and episodes of sudden sleep onset, particularly in patients with Parkinson’s disease. Sudden onset of sleep during daily activities, in some cases without awareness or warning signs, has been reported very rarely.
• All patients receiving bromocriptine should be cautioned with regard to engaging in activities requiring rapid and precise responses, such as driving an automobile or operating machinery.
• Patients receiving bromocriptine for hyperprolactinemic states associated with macroadenoma or those who have had previous transsphenoidal surgery, should be told to report any persistent watery nasal discharge to their physician.
• Patients receiving bromocriptine for treatment of a macroadenoma should be told that discontinuation of drug may be associated with rapid regrowth of the tumor and recurrence of their original symptoms.
• Patients and their caregivers should be alerted to the possibility that patients may experience intense urges to spend money uncontrollably, intense urges to gamble, increased sexual urges and other intense urges and the inability to control these urges while taking bromocriptine. Advise patients and their caregivers to inform their healthcare provider if they develop new or increased uncontrolled spending, gambling urges, sexual urges, or other urges while being treated with bromocriptine
• Especially during the first days of treatment, hypotensive reactions may occasionally occur and result in reduced alertness. Particular care should be exercised when driving a vehicle or operating machinery.
• Bromocriptine should not be used during lactation in postpartum women.
• Since hyperprolactinemia with amenorrhea/galactorrhea and infertility has been found in patients with pituitary tumors, a complete evaluation of the pituitary is indicated before treatment with bromocriptine mesylate.
• Symptomatic hypotension can occur in patients treated with bromocriptine for any indication. Since, especially during the first days of treatment, hypotensive reactions may occasionally occur and result in reduced alertness, particular care should be exercised when driving a vehicle or operating machinery.
• Bromocriptine therapy is associated with low rate of transient serum enzyme elevations during treatment and has been implicated in rare cases of acute liver injury.
