There are many treatments available for this disease. Treatment options include several types of medicines as well as non-medication options.

Am I At Risk:
Restless legs syndrome can occur at any age, but it is more common in older adults. RLS can be hereditary; about 50% of people with RLS have family members with the disease. People who are pregnant, have kidney disease, or other neurological diseases may be at higher risk of having RLS.
People with anemia or low iron levels may have more severe RLS symptoms. Some drugs used to treat depression, nausea and allergies can make RLS symptoms worse.
GENERAL OVERVIEW:
Restless legs syndrome affects about 7% of the population. About 3% of people experience moderate to severe symptoms. Symptoms of RLS can make it difficult to fall asleep and stay asleep. You may wake up and need to pace the floor to relieve symptoms. RLS may cause you to feel tired during the day. Some people with RLS also report worsening of anxiety or depression.
Researchers are trying to determine the exact cause of RLS. It may be caused by changes in certain brain chemicals, such as dopamine. RLS also may be genetic; it is more common among family members. RLS symptoms become more severe in people who have iron deficiency.
There is no specifc test to detect restless legs syndrome. Your doctor will review your symptoms and determine if you have the disease. Sometimes a sleep study is needed to determine if another sleep disorder is disturbing your sleep, but a sleep study is not necessary for the diagnosis of RLS.
Activities such as exercise, leg massages and warm baths can help reduce mild RLS symptoms. Prescription medications can be helpful if you have more severe symptoms. Your doctor will help you decide if a medication is the best option for you. Some medications need to be taken daily at the same time of day. Others need to be taken only when symptoms bother you. Your doctor may recommend iron supplements if your iron levels are low.
TIPS:
- Eat a well-balanced diet including foods rich in iron.
- Get some exercise every day.
- Stretch or massage the legs when you notice RLS symptoms.
- Use heating pads on your legs when you are awake or take a warm bath to reduce symptoms.
- Reduce your level of stress.
- Limit caffeine and alcohol and do not smoke. All of these can worsen RLS.
Next Steps:
- Talk with your doctor about your symptoms. It may help to write down your symptoms including the time of day when they occur.
- Discuss all of your medications and herbal supplements with your doctor. Some of these could cause RLS symptoms or make them worse.
- Your doctor may test your iron levels.
- Your doctor may schedule you for a sleep study if you have symptoms of a sleep disorder like sleep apnea.
