Pharmacological treatments of augmentation in restless legs syndrome patients.

Abstract

Augmentation, a treatment-induced paradoxical worsening of the symptoms of restless legs syndrome (RLS) that is caused by long-term dopaminergic therapy, in particular with higher doses, remains the major challenge of RLS treatment. The mainstay of treatment continues to be preventing augmentation, either by starting RLS therapy with alternative drugs or by sensitizing physicians about the absolute necessity of respecting approved dosages of dopaminergic drugs when treating RLS and never exceeding the maximum recommended dosages. In the case of a positive diagnosis of augmentation, treatment consists of reducing or eliminating dopaminergic therapy, ensuring that serum ferritin is clearly higher than the level assumed to be necessary from a hematological point of view and/or switching treatment to alternative drugs such as α2δ ligands, opiates, or to combination therapy.
