Question: What are the treatments for Restless Legs Syndrome ?
Answer: For those with mild to moderate symptoms, many physicians suggest certain lifestyle changes and activities to reduce or eliminate symptoms. Decreased use of caffeine, alcohol, and tobacco may provide some relief. Physicians may suggest that certain individuals take supplements to correct deficiencies in iron, folate, and magnesium. Taking a hot bath, massaging the legs, or using a heating pad or ice pack can help relieve symptoms in some patients. Physicians also may suggest a variety of medications to treat RLS, including dopaminergics, benzodiazepines (central nervous system depressants), opioids, and anticonvulsants. The drugs ropinirole, pramipexole, gabapentin enacarbil, and rotigotine have been approved by the U.S. Food and Drug Administration for treating moderate to severe RLS. The Relaxis pad, which the person can place at the site of discomfort when in bed and provides 30 minutes of vibrations (counterstimulation) that ramp off after 30 minutes, also has been approved by the FDA.
