Precautions, which may help to prevent or minimize the occurrence of myasthenia crisis include:

• Taking anticholinesterase medicines 30 to 45 minutes before meals to reduce the risk of aspiration (food entering the lung passages)
• Taking anticholinesterase medicines exactly as prescribed to help maintain the strength of the breathing muscles
• Avoiding crowds and contact with people with respiratory infections, such as a cold or the flu
• Taking in proper nutrition to maintain optimal weight and muscle strength
• Balancing periods of physical activity with periods of rest
• Using stress-reduction techniques and avoiding emotional extremes

Tell your healthcare providers about your condition when any medicines are being prescribed. Certain medicines may interfere either with the disease or the action of the medicines you take for myasthenia gravis.
