Important side-effects

Cardiac Valvulopathy. All patients should undergo a cardiovascular evaluation, including echocardiogram to assess the potential presence of valvular disease. If valvular disease is detected, the patient should not be treated with pergolide. Pergolide should be discontinued if an echocardiogram reveals new valvular regurgitation, valvular restriction or valve leaflet thickening. The risk of developing valvular disease is dose dependent.
