  • Anticonvulsants, or anti-seizure drugs, such as Lyrica, Tegretol, Neurontin, and Horizant.
    Though there is no cure for restless legs syndrome, recent treatments can aid in controlling the condition, reducing symptoms, and enhancing sleep.

  • Amyloidosis (build-up of a starch-like substance in the body’s tissues and organs)
  • Damage to spinal nerves
  • Lyme disease
  • Rheumatoid arthritis and Sjögren syndrome
