The biggest risk is liver toxicity. The patient should have blood work done very frequently to alert the physician of any toxicity, if this does occur, the patient is usually taken off the medication. The use of cortosteroids has been carefully weighed. This is an effective treatment for MG, despite the side effects. This means the patient has respiratory arrest and must go on a ventilator.
Plasmapheresis is the drawing off of plasma.
This is only a short-term treatment to bring the patient off ventilation, and only lasts a few weeks. When I was told I had this disease, I was concerned because I couldn't even pronounce it, let alone know anything about it. It started with simple double vision and escalated to weakness in my limbs. I wanted to know everything I could about this disease, but information on it is difficult to access. I had to scour libraries and doctor's offices for everything I could get my hands on.
