Prevention of Myasthenia Gravis

Myasthenia gravis cannot be prevented, but avoiding the following triggers may help patients prevent exacerbation:

  • Emotional stress
  • Exposure to extreme temperatures
  • Fever
  • Illness (e.g., respiratory infection, pneumonia, tooth abscess)
  • Low levels of potassium in the blood (hypokalemia; caused by diuretics, frequent vomiting)
  • Medications (e.g., muscle relaxants, anticonvulsants, certain antibiotics)
  • Overexertion
