The management of patients with diabetes insipidus can be confusing be
cause of the disorder's variable pathophysiology, the numerous medicat
ions used, and the possible complications related to their use. Nevert
heless, the primary care physician, rather than the subspecialist, wil
l increasingly be called on to manage patients with such relatively un
common conditions in the future. Ifa few basic facts and principles ar
e kept in mind, the care of most patients with diabetes insipidus can
be successful. A comprehensive, practical review of the short- and lon
g-term therapy for patients with diabetes insipidus, including central
diabetes insipidus, nephrogenic diabetes insipidus, and the ''excessi
ve vasopressinase syndrome,'' is presented. The use of single and mult
idrug regimens, and of the newly marketed oral formulation of desmopre
ssin acetate, is described for common clinical settings.
