There are 3 approved treatments for CIDP; steroids like prednisone or methylprednisolone, Immunoglobulin (Ig) either intravenously or subcutaneously and therapeutic plasma exchange, also known as plasmapheresis, although the latter is rarely used. Whether opne of the steroids or Ig is used depends on multiple factors and often comes down to the preference of individual prescribing physicians. Steroids are more convenient to take since they are given by mouth, either daily, on alterant days or once a week but they tend to have more side effects. Ig needs to be given by injection so is less convenient but is preferred by some doctors because there are fewer side effects. There are a number of higher risk treatments that can be effective but are used only when the initially chosen treatment is not optimally effective or has unacceptible side effects. It is important to discuss with your doctor which is the preferred treatment for you based on a careful analysis of risks and benefits.
