This usually happens within three weeks. This is not a contagious disease. Supportive treatment is important especially if there are problems breathing or swallowing. Some corticosteroids, such as prednisone, can reduce nerve inflammation. Corticosteroids are not as helpful for severe cases.
Corticosteroids are much more commonly used if the disorder continues.
A procedure called plasmapheresis can be effective if used early in the course of the illness. Plasmapheresis removes antibodies that may be present in the bloodstream and adds fluids or plasma back that do not have the antibodies. Giving these treatments early can shorten the duration of the inflammation and can help recovery occur more quickly. Frequently if there are problems with breathing or swallowing, hospitalization may be required. Breathing problems may be assisted by a ventilator.
