There are many effective treatments for myasthenia gravis. Spontaneous improvement and even remission (although uncommon) may occur without specific therapy.
Plasmapheresis, or plasma exchange, may be useful in the treatment of MG also. This procedure removes the abnormal antibodies from the plasma of the blood. The improvement in muscle strength may be striking, but is usually short-lived, since production of the abnormal antibodies continues. When plasmapheresis is used, it may require repeated exchanges. Plasmapheresis may be especially useful during severe MG weakness or prior to surgery.
