  Bromocriptine Mesylate

  

  ---

  General

  It is recommended that bromocriptine mesylate be taken with food. Patients should be evaluated frequently during dose escalation to determine the lowest dosage that produces a therapeutic response.  

  Hyperprolactinemic Indications

  The initial dosage of bromocriptine mesylate tablets in adults is one-half to one 2.5 mg scored tablet daily. An additional 2.5 mg tablet may be added to the treatment regimen as tolerated every 2-7 days until an optimal therapeutic response is achieved. The therapeutic dosage ranged from 2.5-15 mg daily in adults studied clinically.

  Based on limited data in children of age 11 to 15, (see Pediatric use subsection) the initial dose is one-half to one 2.5 mg scored tablet daily. Dosing may need to be increased as tolerated until a therapeutic response is achieved. The therapeutic dosage ranged from 2.5-10 mg daily in children with prolactin-secreting pituitary adenomas.

  In order to reduce the likelihood of prolonged exposure to bromocriptine mesylate should an unsuspected pregnancy occur, a mechanical contraceptive should be used in conjunction with bromocriptine mesylate therapy until normal ovulatory menstrual cycles have been restored. Contraception may then be discontinued in patients desiring pregnancy.

  Thereafter, if menstruation does not occur within 3 days of the expected date, bromocriptine mesylate therapy should be discontinued and a pregnancy test performed.

  Acromegaly

  Virtually all acromegalic patients receiving therapeutic benefit from bromocriptine mesylate also have reductions in circulating levels of growth hormone. Therefore, periodic assessment of circulating levels of growth hormone will, in most cases, serve as a guide in determining the therapeutic potential of bromocriptine mesylate. If, after a brief trial with bromocriptine mesylate therapy, no significant reduction in growth hormone levels has taken place, careful assessment of the clinical features of the disease should be made, and if no change has occurred, dosage adjustment or discontinuation of therapy should be considered.

  The initial recommended dosage is 1/2 to one 2.5 mg bromocriptine mesylate tablet on retiring (with food) for 3 days. An additional 1/2 to 1 tablet should be added to the treatment regimen as tolerated every 3 to 7 days until patient obtains optimal therapeutic benefit. Patients should be reevaluated monthly and the dosage adjusted based on reductions of growth hormone or clinical response. The usual optimal therapeutic dosage range of bromocriptine mesylate varies from 20 to 30 mg per day in most patients. The maximum dosage should not exceed 100 mg per day.

  Patients treated with pituitary irradiation should be withdrawn from bromocriptine mesylate therapy on a yearly basis to assess both the clinical effects of radiation on the disease process as well as the effects of bromocriptine mesylate therapy. Usually a 4 to 8 week withdrawal period is adequate for this purpose. Recurrence of the signs/symptoms or increases in growth hormone indicate the disease process is still active and further courses of bromocriptine mesylate should be considered.

  Parkinson's Disease

  The basic principle of bromocriptine mesylate therapy is to initiate treatment at a low dosage and, on an individual basis, increase the daily dosage slowly until a maximum therapeutic response is achieved. The dosage of levodopa during this introductory period should be maintained, if possible. The initial dose of bromocriptine mesylate is 1/2 of a 2.5 mg tablet twice daily with meals. Assessments are advised at two week intervals during dosage titration to ensure that the lowest dosage producing an optimal therapeutic response is not exceeded. If necessary, the dosage may be increased every 14 to 28 days by 2.5 mg per day with meals. Should it be advisable to reduce the dosage of levodopa because of adverse reactions, the daily dosage of bromocriptine mesylate, if increased, should be accomplished gradually in small (2.5 mg) increments. The safety of bromocriptine mesylate has not been demonstrated in dosages exceeding 100 mg per day.
