Nervous system

• Very common (10% or more): Headache (up to 26%), dizziness (up to 17%)
• Common (1% to 10%): Dizziness/vertigo, dyskinesia, paresthesia, somnolence
• Uncommon (0.1% to 1%): Hyperkinesia
• Frequency not reported: Sudden sleep onset, syncope, tremor^[Ref]

Other

• Common (1% to 10%): Asthenia
• Uncommon (0.1% to 1%): Fatigue, malaise^[Ref]

• Very common (10% or more): Peripheral edema

Reports of cardiac valvulopathy have generally been received in patients on higher doses (greater than 2 mg/day); however, there have been cases in patients receiving lower doses for the treatment of hyperprolactinemic disorders. In a multi-country, retrospective cohort study, record review looking for an association between the new use of dopamine agonists (including this drug; n=27,812) and cardiac valvular regurgitation (CVR), other fibrosis, and other cardiopulmonary events found an increased risk of CVR among patients with Parkinson's disease when compared to non-ergot derived dopamine agonists and levodopa. Analysis in patients with hyperprolactinemia treated with this drug (n=8386) found that compared to non-users, exposed persons did not have an elevated risk of CVR. These findings are consistent with other published studies.^[Ref]
