Restless legs syndrome

Diagnosis

To diagnose restless legs syndrome, your healthcare professional takes your medical history and asks about your symptoms. A diagnosis of RLS is based on the following criteria, established by the International Restless Legs Syndrome Study Group:

• You have a strong, often irresistible urge to move the legs. This usually occurs with uncomfortable feelings in the legs.
• Your symptoms start or get worse when you’re resting, such as sitting or lying down.
• Your symptoms are partially or temporarily relieved by activity, such as walking or stretching.
• Your symptoms are worse at night.
• Symptoms can’t be explained solely by another medical or behavioral condition.

Your healthcare professional may conduct a physical and a neurological exam. Blood tests, particularly for iron deficiency, may be ordered to rule out other possible causes of your symptoms.

You may be referred to a sleep specialist. This may involve an overnight stay and a study at a sleep clinic if another sleep condition such as sleep apnea is suspected. However, a diagnosis of RLS usually doesn’t require a sleep study.

Treatment

Symptoms of restless legs syndrome sometimes go away after treating an underlying condition, such as iron deficiency. Correcting an iron deficiency may involve taking an iron supplement by mouth. Or you may be given an iron supplement through a vein in your arm. Take iron supplements only with medical supervision and after having your blood-iron level checked.

If you have RLS without an associated condition, treatment focuses on lifestyle changes. If those aren’t effective, your healthcare professional may prescribe medicines.

Medications

Several prescription medicines are available to reduce the restlessness in the legs. Many of the medicines were developed to treat other diseases, but they may help with RLS. Medicines include:

  Medicines that increase dopamine in the brain. These medicines affect levels of the chemical messenger dopamine in the brain. Rotigotine (Neupro), pramipexole (Mirapex ER) and ropinirole are approved by the Food and Drug Administration for the treatment of moderate to severe RLS.

  Short-term side effects of these medicines are usually mild and include nausea, lightheadedness and fatigue. However, they also can cause issues with impulse control, such as compulsive gambling. They also can cause daytime sleepiness.

  Sometimes dopamine medicines that have worked for a while to relieve RLS stop working. Or you may notice your symptoms return earlier in the day or involve your arms. This is called augmentation. If this happens, your healthcare professional may substitute another medicine.

  People who have occasional RLS symptoms may be prescribed carbidopa-levodopa (Duopa, Rytary, others) to take as needed. But healthcare professionals don’t recommend taking this medicine daily or near daily. Daily use of this medicine can cause augmentation.

• Medicines affecting calcium channels. Medicines such as gabapentin (Neurontin, Gralise), gabapentin enacarbil (Horizant) and pregabalin (Lyrica), work for some people with RLS.
• Muscle relaxants and sleep medicines. These medicines help you sleep better at night, but they don’t eliminate the leg sensations. They also may cause daytime drowsiness. These medicines may only be used if no other treatment provides relief.
• Opioids. These medicines are used mainly to relieve serious symptoms, but they may be addicting if used in high doses. Some examples include tramadol (ConZip, Qdolo), codeine, oxycodone (Oxycontin, Roxicodone, others) and hydrocodone (Hysingla ER).

It may take several trials to find the right medicine or combination of medicines that work best for you.

Most medicines prescribed to treat RLS aren’t recommended during pregnancy. Instead, self-care techniques may be recommended to relieve symptoms. But if symptoms are bothersome during your last trimester, your healthcare professional may approve the use of certain medicines.

And some medicines may worsen symptoms of RLS. These include some antidepressants, some antipsychotic medicines, some anti-nausea medicines, and some cold and allergy medicines. Your healthcare professional may recommend that you don’t take these medicines, if possible. However, if you need to take them, talk about treatments to help manage RLS.

Lifestyle and home remedies

Making simple lifestyle changes can help alleviate symptoms of restless legs syndrome:

• Try baths and massages. Soaking in a warm bath and massaging the legs can relax the muscles.
• Apply warm or cool packs. Use of heat or cold, or alternating use of the two, may lessen the leg sensations.
• Establish good sleep hygiene. Fatigue tends to worsen symptoms of RLS, so it’s important that you practice good sleep hygiene. Create a cool, quiet, comfortable sleeping environment. Go to bed and rise at the same time daily. Get at least seven hours of sleep nightly.
• Exercise. Moderate, regular exercise may relieve symptoms of RLS. But overdoing it or working out too late in the day may make symptoms worse.
• Avoid caffeine. Sometimes cutting back on caffeine may help restless legs. Try to avoid caffeine-containing products for a few weeks to see if this helps. This includes cutting out chocolate, coffee, tea and soda.
• Consider using a foot wrap or a vibrating pad. A foot wrap specially designed for people with RLS puts pressure under the foot and may help relieve your symptoms. You also may find relief using a pad that vibrates on the back of the legs.

Coping and support

Restless legs syndrome is most often a lifelong condition. It may help you to develop coping strategies that work for you, such as:

• Tell others about your condition. Sharing information about RLS helps your family, friends and coworkers better understand what you’re going through. It can help explain why you might pace the halls or stand at the back of the theater. It may help coworkers better understand if they see you walk to the water cooler many times during the day.
• Don’t resist your need for movement. If you attempt to suppress the urge to move, you may find that your symptoms worsen.
• Keep a sleep diary. Keep track of the medicines and strategies that help symptoms. Also note what makes symptoms worse. Share this information with your healthcare professional.
• Stretch and massage. Begin and end your day with stretching exercises or gentle massage.
• Seek help. Support groups bring together family members and people with RLS. By participating in a group, your insights not only can help you but also may help someone else.

Preparing for your appointment

If you have symptoms of restless legs syndrome, make an appointment with your healthcare professional. You may be referred to a doctor who specializes in conditions affecting the nervous system, known as a neurologist, or a sleep specialist.

Here’s some information to help you get ready for your appointment.

What you can do

• Write down key medical information, including other conditions you have. Also include medicines you take, including prescription, those you get without a prescription, vitamins and supplements. And note whether there’s a history of RLS in your family.
• Take a family member or friend along. Someone who accompanies you may remember information you missed or forgot.
• Write down questions to ask.
