Incidence of Drug-related Adverse Events [ Time Frame: 12 Months ]
Number of patients with drug-related adverse events
Secondary Outcome Measures :
Change From Baseline in Total Score of the International Restless Legs Syndrome Rating Scale (IRLS) [ Time Frame: after 12 months or at the end of observation ]
International Restless Legs Syndrome rating scale (IRLS): The IRLS rating scale is a selfrating scale used to evaluate the severity of RLS and the patients are requested to answer 10 questions on a scale of 0 to 4. Respective scores (0-4 points) for the 10 questions were added up to calculate the total score on the IRLS. Therefore the total score is 0-40. The lower values represent a better outcome.
