Oral Iron Frequency for Childhood Restless Leg Syndrome/Periodic Limb Movement Disorder
January 6, 2023 updated by: Julie M. Baughn, Mayo Clinic
Optimum Frequency and Timing of Oral Iron Administration for Childhood Restless Leg Syndrome/Periodic Limb Movement Disorder
The purpose of this research study is to see if the level of serum ferritin differs based on how often oral iron (in the form of ferrous sulfate) is given to children with restless leg syndrome/periodic limb movement disorder.
