The risk of using bromocriptine mesylate in combination with other drugs has not been systematically evaluated, but alcohol may potentiate the side effects of bromocriptine mesylate. Bromocriptine mesylate may interact with dopamine antagonists, butyrophenones, and certain other agents. Compounds in these categories result in a decreased efficacy of bromocriptine mesylate: phenothiazines, haloperidol, metoclopramide, pimozide. Concomitant use of bromocriptine mesylate with other ergot alkaloids is not recommended.
Uncontrolled hypertension and sensitivity to any ergot alkaloids. In patients being treated for hyperprolactinemia bromocriptine mesylate should be withdrawn when pregnancy is diagnosed (see PRECAUTIONS Hyperprolactinemic States). In the event that bromocriptine mesylate is reinstituted to control a rapidly expanding macroadenoma (see PRECAUTIONS, Hyperprolactinemic States) and a patient experiences a hypertensive disorder of pregnancy, the benefit of continuing bromocriptine mesylate must be weighed against the possible risk of its use during a hypertensive disorder of pregnancy. When bromocriptine mesylate is being used to treat acromegaly, prolactinoma, or Parkinson's disease in patients who subsequently become pregnant, a decision should be made as to whether the therapy continues to be medically necessary or can be withdrawn. If it is continued, the drug should be withdrawn in those who may experience hypertensive disorders of pregnancy (including eclampsia, preeclampsia, or pregnancy-induced hypertension) unless withdrawal of bromocriptine mesylate is considered to be medically contraindicated.
The drug should not be used during the post-partum period in women with a history of coronary artery disease and other severe cardiovascular conditions unless withdrawal is considered medically contraindicated. If the drug is used in the post-partum period the patient should be observed with caution.
