Is cymbalta effective for idiopathic rls ? why some neurologist prescribe anti-depressant to treat rls symptoms? its a life long disease in most cases, does that mean lifelong anti-depressant???

Cymbalta is unlikely to be very effective in dealing with RLS. More effective agents include dopamine agonists, gabapentin, Lyrica, and on occasion L-DOPA. Antidepressants are used by some neurologists for a host of off-label indications, often due to lower costs associated with generic status. Be assertive with your doctor and get full explanation for treatment choices.
