Restless legs syndrome in narcolepsy: a side effect of sodium oxybate?
Gamma-hydroxybutyrate (GHB) has re-emerged as a major treatment for narcolepsy. As dopaminergic transmission is clearly involved in the pathophysiology of restless legs syndrome (RLS), and GHB reduces dopamine release, one may hypothesize that RLS may occur in narcolepsy in the presence of GHB. We report a case of narcolepsy with a severe occurrence of typical RLS with GHB, symptoms never previously experienced by the subject and reversible after withdrawal.
