Hi Wendy,
Regardless of the amount or length of time you took it or the dosage an echocardiogram is recommended to rule out valvulopathy which has an increased chance of occurring in people who have previously taken Permax.
Your G.P. or neurologist will probably be aware of the reports regarding the increased chance of it in pts who took Permax.
If they're not you can teach them something they don't know and in return they can find you a cardiologist who will order an echocardiogram and hopefully report you have no evidence of valvulopathy.
Cheers,
Lee
