Skeletal muscle relaxants are often used to relieve tenderness and muscle spasms related to various types of musculoskeletal conditions. These conditions tend to be acute and are quite common. Such conditions include:

• Fibromyalgia
  
  
• Mechanical low-back or neck pain
  
  
• Myofascial pain syndromes
  
  
• Nocturnal leg cramps
  
  
• Tension headaches

Skeletal muscle relaxants also may be used to treat neurological conditions associated with spasticity. This is a condition characterized by tight or stiff muscles and an inability to control those muscles. For many patients, spasticity can be disabling and painful. These conditions are chronic, but tend to be less common than musculoskeletal conditions. Neurological conditions that may be treated with skeletal muscle relaxants include:

• Cerebral palsy
  
  
• Multiple sclerosis
  
  
• Muscle spasms following strokes
  
  
• Spinal cord injuries
  
  
• Traumatic brain injury
