Adverse events most commonly reported in clinical trials of bromocriptine included nausea, fatigue, vomiting, headache, and dizziness. These events were more likely to occur during initial titration of the drug and lasted a median of 14 days. Nausea and vomiting were not described as serious.

Bromocriptine can cause orthostatic hypotension and syncope, particularly on initiation of therapy and dose escalation. Caution is advised when treating patients who are receiving antihypertensive therapy; orthostatic vital signs should be evaluated at baseline and periodically thereafter.
