PLMD/RLS Treatment
Generally, there are three classes of drugs that are used to treat PLMD and RLS. These are benzodiazepines, Parkinson drugs, and narcotics. Medical treatment of PLMD and RLS often significantly reduces or eliminates the symptoms of these disorders, although not always. There is no cure for PLMD or RLS, and medical treatment must be continued to provide potential relief.
Clonazepam is the most commonly employed benzodiazepine treatment. It is effective in many cases, but not all, and it usually causes drowsiness or sedation. Sometimes, clonazepam allows the patient a better, more restful night's sleep without affecting the occurrence of limb movement. Patients with PLMD may have other sleep disorders, such as obstructive sleep apnea, which the use of clonazepam could worsen.
The drugs used to treat Parkinson's disease are also very effective against PLMD and RLS. These include, L-dopa/carbidopa, bromocriptine (which suppresses the excretion of prolactin), pergolide, and selegiline. If either benzodiazepines or Parkinson's medications do not relieve symptoms, then narcotics, such as codeine, oxycodone, methadone, and propoxyphene are sometimes employed.
In May of 2005, ropinirole hydrochloride (e.g., Requip®), which also is used to treat Parkinson's disease, was approved by the Food and Drug Administration (FDA) to treat moderate-to-severe (i.e., 15 or more episodes per month) restless legs syndrome. This medication may result in extreme drowsiness and may cause patients to fall asleep during daily activities (e.g., driving). Other side effects include dizziness, nausea and vomitting, sweating upon standing.
