Studies on therapeutic interventions of RLS during pregnancy are lacking. The major goal of therapy is to provide symptomatic relief (Figure 1). Conservative measures are recommended in mild cases. In moderate to severe cases, pharmacological therapy may be warranted. Dopaminergic agents are the drugs of choice in RLS. The non-ergo-derived dopamine agonists (e.g. ropinirole and pramipexole) are FDA approved for RLS, but pregnancy safety data is limited. Opioids are also efficacious. Side effects and possible neonatal withdrawal syndrome may limit use during pregnancy. Benzodiazepines are also effective but use is limited due to the risk of teratogenicty. Intravenous magnesium sulfate used in preterm labor completely abolished RLS symptoms in one case. Magnesium has a depressant effect on neuronal excitability and alleviates symptoms in some RLS patients.
