Just to make sure that you understand, Prednisone is not a cure for insulinoma. It alleviates the symptoms for a time. Dr. Weiss is one of the best vets in the country for treating insulinoma, so your ferret is in good hands. Generally, if the insulinoma is in the early stages and the ferret is otherwise in good health, surgery is usually the best option. Dr. Weiss removes up to 1/3 of the pancreas. That may delay recurrence of the signs for well over a year, at which point, another surgery is an option or Prednisone treatment may be started. With surgery and luck, the ferret may live for several years. With Prednisone only; perhaps a year to a year and a half. Dick B. - not a vet [Posted in FML issue 2447]
