What are the treatment options for Restless Legs Syndrome (RLS)?

From the Guidelines

Restless leg syndrome can be effectively managed through a combination of lifestyle changes and medications, with the American Academy of Sleep Medicine suggesting the use of ferrous sulfate over no ferrous sulfate in patients with appropriate iron status 1. To manage restless leg syndrome, it's essential to start with lifestyle changes, such as improving sleep habits, reducing caffeine and alcohol intake, and engaging in regular moderate exercise. For mild symptoms, try warm baths, leg massages, or applying heat or cold packs. Some key points to consider when treating restless leg syndrome include:

• The use of ferrous sulfate is recommended for patients with appropriate iron status, as it has been shown to be effective in reducing symptoms 1.
• Dopamine agonists, such as pramipexole or ropinirole, may be used as first-line treatments, but their use is conditional and based on individual patient preferences and values 1.
• Alpha-2-delta calcium channel ligands, such as gabapentin or pregabalin, may be used, particularly if pain is present, but their use is also conditional and based on individual patient needs 1.
• Low-dose opioids, such as oxycodone or methadone, may be considered for severe cases, but only under close medical supervision due to addiction risks 1.
• Iron supplementation, such as ferrous sulfate, is recommended if ferritin levels are below 75 ng/mL, as it can help alleviate symptoms 1. It's crucial to start with the lowest effective dose and adjust as needed, as some medications can cause augmentation (worsening symptoms) with long-term use. Regular follow-ups with a healthcare provider are essential to monitor effectiveness and side effects. In terms of specific medications, the American Academy of Sleep Medicine suggests against the standard use of levodopa, pramipexole, transdermal rotigotine, and ropinirole, due to the risk of augmentation and other adverse effects 1. However, these medications may be used in individual patients who place a higher value on the reduction of restless legs symptoms with short-term use and a lower value on adverse effects with long-term use. Overall, the treatment of restless leg syndrome should be tailored to the individual patient's needs and preferences, with a focus on minimizing risks and maximizing benefits.

From the FDA Drug Label

The effectiveness of ropinirole in the treatment of RLS was demonstrated in randomized, double-blind, placebo-controlled trials in adults diagnosed with RLS using the International Restless Legs Syndrome Study Group diagnostic criteria Patients were required to have a history of a minimum of 15 RLS episodes/month during the previous month and a total score of ≥15 on the International RLS Rating Scale (IRLS scale) at baseline. A variety of measures were used to assess the effects of treatment, including the IRLS scale and Clinical Global Impression-Global Improvement (CGI-I) scores In all 3 trials, a statistically significant difference between the treatment group receiving ropinirole and the treatment group receiving placebo was observed at Week 12 for both the mean change from baseline in the IRLS scale total score and the percentage of patients rated as responders (much improved or very much improved) on the CGI-I

Ropinirole is effective in the treatment of Restless Legs Syndrome (RLS). The drug has been shown to significantly reduce symptoms of RLS, as measured by the International RLS Rating Scale (IRLS) and the Clinical Global Impression-Global Improvement (CGI-I) scale, in three randomized, double-blind, placebo-controlled trials 2.

• Key benefits of ropinirole in the treatment of RLS include:
  • Significant reduction in RLS symptoms
  • Improvement in sleep quality and daytime functioning
  • Long-term maintenance of efficacy
• Dosage: The recommended dosage of ropinirole for the treatment of RLS is 0.25 mg to 4 mg once daily, taken 1 to 3 hours before bedtime.

Restless Leg Syndrome Treatment Options

• Non-pharmacological interventions such as repetitive transcranial magnetic stimulation, exercise, compression devices, counterstrain manipulation, infrared therapy, and standard acupuncture may be beneficial for reducing RLS severity 3
• Vibration pads, cryotherapy, yoga, compression devices, and acupuncture may improve some sleep-related outcomes in RLS patients 3
• Non-pharmacological measures such as massage or temperate baths may provide adequate symptom control for some people with RLS 4
• First-line management options include iron-replacement therapy, gabapentin, pregabalin, and dopamine agonists such as pramipexole, ropinirole, and rotigotine 4
• Second-line therapies include intravenous iron infusion and opioids such as tramadol, oxycodone, and methadone 4
• Alternative practices such as mind-body interventions (conventional exercise, yoga, and acupuncture), lifestyle interventions (pneumatic compression devices, light therapy, and cognitive-behavioral therapy), and neutraceuticals (vitamins, valerian, and Chinese herbs) may be considered for RLS treatment 5
• Regular physical activity and oral iron supplementation may be recommended for RLS symptoms 5
• Dopaminergic agents, such as levodopa and dopamine agonists, are considered first-line treatment for RLS 6
• Pharmacologic treatment should be limited to patients with clinically relevant RLS and impaired sleep quality or quality of life 6
• Nonpharmacologic treatment options have limited evidence, but may be considered in moderate to severe primary RLS 7
• Treatment options in case of augmentation include iron suppletion, an α2δ ligand, a dopamine agonist, a combination of an α2δ ligand and a dopamine agonist, or oxycodone/naloxone 7
