title: High-dose clonidine in a case of restless legs syndrome.
abstract: OBJECTIVE
  To describe a patient with idiopathic restless legs syndrome (RLS).
  
  
  METHODS
  A 37-year-old man developed severe symptoms of RLS. Treatment using combinations of levodopa, opioids, benzodiazepines, and baclofen provided only partial benefit or resulted in intolerable adverse effects. Higher dosages of clonidine than previously reported in the literature (0.9 mg/d in divided doses) were needed to completely relieve his RLS symptoms. The only prominent adverse effect was dry mouth. The RLS symptoms returned after subsequent reductions in the dosage. After the dosage of clonidine was again increased, complete relief of the symptoms was achieved again. After several months, clonidine was tapered to zero and the patient entered a period of spontaneous remission. When his symptoms returned four months after clonidine had been discontinued, clonidine therapy was restarted.
  
  
  CONCLUSIONS
  Clonidine alleviated RLS symptoms in 30 of 41 patients reported in the literature, indicating that the adrenergic nervous system may play a role in RLS.
  
  
  CONCLUSIONS
  High-dose clonidine appears to be useful in treating RLS when other therapies fail. However, well-controlled, polysomnographic studies are needed.
