Treatment Options for Restless Leg Syndrome

Initial Management Approach

The American Academy of Sleep Medicine recommends that the first step in RLS management should be identifying and addressing exacerbating factors, including alcohol, caffeine, antihistaminergic medications, serotonergic medications, antidopaminergic medications, and untreated obstructive sleep apnea 3, 4
The American Academy of Sleep Medicine suggests testing serum iron studies including ferritin and transferrin saturation in all patients with clinically significant RLS 3, 5
The American Academy of Sleep Medicine recommends testing should be done in the morning after avoiding iron-containing supplements and foods for at least 24 hours 3, 5

The American Academy of Sleep Medicine recommends providing iron supplementation if serum ferritin ≤ 75 ng/mL or transferrin saturation < 20% 3, 5
The American Academy of Sleep Medicine suggests using oral iron (ferrous sulfate) for mild iron deficiency (conditional recommendation, moderate certainty) 1, 6
The American Academy of Sleep Medicine recommends using IV iron formulations when ferritin is between 75-100 ng/mL or when oral supplementation is ineffective 3, 4
The American Academy of Sleep Medicine strongly recommends IV ferric carboxymaltose (strong recommendation, moderate certainty) 1, 4

The American Academy of Sleep Medicine strongly recommends gabapentin enacarbil for adults with RLS (strong recommendation, moderate certainty) 1, 2
The American Academy of Sleep Medicine strongly recommends gabapentin for adults with RLS (strong recommendation, moderate certainty) 1, 2
The American Academy of Sleep Medicine strongly recommends pregabalin for adults with RLS (strong recommendation, moderate certainty) 1, 2

The American Academy of Sleep Medicine suggests against standard use of dopaminergic agents due to risk of augmentation (a paradoxical worsening of symptoms with long-term use) 1, 8
The American Academy of Sleep Medicine recommends that dopaminergic agents should be reserved for short-term treatment in patients who prioritize immediate symptom relief over long-term adverse effects 8, 6
The American Academy of Sleep Medicine conditionally recommends against levodopa (conditional recommendation against standard use, very low certainty) 7, 6
The American Academy of Sleep Medicine conditionally recommends against pramipexole (conditional recommendation against standard use, moderate certainty) 8, 6
The American Academy of Sleep Medicine strongly recommends against cabergoline use (strong recommendation, moderate certainty) 6

The American Academy of Sleep Medicine recommends that treatment selection for RLS in pregnancy should consider pregnancy-specific safety profiles 1, 3
The American Academy of Sleep Medicine suggests that non-pharmacologic approaches may be preferred during pregnancy 3
The American Academy of Sleep Medicine conditionally recommends gabapentin for patients with RLS and end-stage renal disease (conditional recommendation, very low certainty) 6
The American Academy of Sleep Medicine suggests IV iron sucrose for patients with ferritin < 200 ng/mL and transferrin saturation < 20% 6
