Abstract
Purpose of review
The main purpose of this manuscript is to review the existing clinical evidence about when iron replacement therapy should be initiated for RLS/WED, and how it should be administered (oral vs. intravenous).
Recent findings
Our knowledge of the pathophysiology of restless legs syndrome/Willis-Ekbom (RLS/WED) continues to grow, revealing the existence of brain iron deficiency as the most well-known biological alteration behind this disorder. Since iron replacement therapy in RLS/WED is one of the first-line available treatments, its indication should be considered periodically, at both the beginning and during the follow-up.
Summary
There is more and more evidence sustaining that the proper use of iron replacement therapy may lead to a reduction in symptomatic drug requirements, and therefore minimize the risk of complications that may result from their long-term use. For all the above, treatment paradigms for RLS/WED, previously based on symptomatic drugs, are changing, giving iron replacement therapy the importance it merits. Thus, it is essential for neurologists to be updated on why, when, and how to use iron in RLS/WED.
