In Restless Legs Syndrome/PLMD management, which intervention is indicated when ferritin is low?

Low ferritin signals depleted iron stores, which contributes to Restless Legs Syndrome by limiting iron available in the brain for dopamine-related pathways. Replacing iron directly addresses this deficit, making iron supplementation the appropriate intervention when ferritin is low. Iron is a critical cofactor for enzymes involved in dopamine synthesis, and CNS iron deficiency is linked to more severe RLS symptoms; restoring iron stores often improves symptoms and reduces PLMS. Depending on how low ferritin is and how well iron is absorbed, you can give iron orally or intravenously, with monitoring of ferritin and transferrin saturation to avoid overload. Other options like a dopaminergic agonist, alpha-2-delta calcium channel ligands, or hypnotics can help with symptoms or sleep, but they do not replenish iron stores and are typically used after addressing iron deficiency or as adjuncts.
