Inadequate dialysis, low iron levels, and anemia are all associated with restless leg syndrome in dialysis patients.
I just started on Requip. The smallest dosage - .5 mg has worked wonders for me. I have not had the fatigue side effect, I usually take it about 1-2 hours before bedtime as directed and it definitely helps with the end of day RLS that I get. My primary care doctor and neph both state that it is okay for me to take even with the ESRD.
A low dose of Mirapex (Pramipexole) helped me. Interestingly, over the last 6 months when my kidneys finally started to fail and my creatinine level went from the 4s to 11+ the RLS symptoms seem to have lessened. Can't say if there is any correlation, but I've had mild RLS for years.
