Myasthenia Gravis

How is myasthenia gravis treated?

• Intravenous Immune Globulin (IVIG) Treatment
  IVIG is derived from donated blood and contains normal antibodies that temporarily counteract the abnormal antibodies in the body.
• Plasma Exchange (Plasmapheresis)
  Abnormal antibodies are filtered out of the body by a machine, similar to the concept of dialysis.
  
  IVIG or plasmapheresis is used in acute cases.
• Medications
  Medication such as pyridostigmine is prescribed to improve muscle weakness. Common side effects include increased salivation, diarrhoea and abdominal discomfort.
  
  Immunosuppressant such as steroid is prescribed to suppress the immune system. Side effects include weight gain, water retention, acne, hypertension, diabetes, infections, gastric ulcers, osteoporosis and cataracts. These side effects can be minimised with diet modications and medications.
  
  The above list is not exhaustive and you should discuss these treatment options further with your doctor.
• Surgery
  In certain instances (e.g. thymoma), removal of the thymus gland is necessary.
  
  With proper treatment, signs and symptoms of MG can be relieved and normal daily function achieved.
