Restless Legs Syndrome

Prevention

Although there is no way to prevent restless legs syndrome, it may help to avoid caffeine, alcohol and cigarette smoking.

Treatment

Treatment of restless legs syndrome depends on the severity of your symptoms. If your symptoms are mild, simply exercising, stretching or massaging your legs, or taking a hot bath may bring relief. Lifestyle changes also may help, especially following a balanced diet and avoiding caffeine, alcohol and cigarette smoking. If your restless legs syndrome is linked to iron deficiency anemia, your doctor may prescribe iron.

When medication is used to treat restless legs syndrome, the following drugs are used individually or in combination:

• Dopaminergic agents - These drugs usually relieve the discomfort of restless legs syndrome symptoms and improve sleep quality. They include carbidopa/levodopa (Sinemet), pramipexole (Mirapex) and ropinirole (Requip).

• Benzodiazepines - These drugs are sedatives that improve sleep quality. They include clonazepam (Klonopin), temazepam (Restoril), triazolam (Halcion) and diazepam (Valium).

• Opioids - These are narcotics, such as codeine (several brand names), propoxyphene (Darvon) or oxycodone (OxyContin and others), that relieve pain and suppress restless legs syndrome in people with severe, unrelenting symptoms.

• Anticonvulsants - These medicines are especially useful in patients whose symptoms are painful. They include gabapentin (Neurontin), carbamazepine (Tegretol and others) and valproic acid (Depacon, Depakene, Depakote).

• Others - Tramadol (Ultram), clonidine (Catapres), amantadine (Symadine, Symmetrel) and propranolol (Inderal) also may be useful to treat this condition. Tramadol is a non-opiod pain reliever that sometimes is recommended.

Many people with restless legs syndrome also have periodic limb movement disorder (PLMD), a common movement disorder that causes involuntary, periodic, jerking leg movements during sleep. The movements occur 1 to 10 times per minute. The degree of periodic limb movement and how it affects sleep is best assessed with a sleep study (polysomnogram).
