Joyce, I don't know anything about that medication, but did want to refer you to
www.rxlist.com. It is a wonderful resource for finding information about medications and has both the information you get as a patient and the more detailed prescribing information.
You could always try my grandmother's remedy for restless legs. She slept with a little cloth bag of corks in her bed, and insisted that it cured her restless legs. There was always some speculation in the family as to whether the it was the corks that helped, or the wine she had to drink to get the corks

Of course, she also took her quinine in the form of tonic water mixed with gin. She lived to be 99, and lived independently until her last few years, though, so whatever works!
