a) 1 micrograms/kg SubQ gives a duration of action of 3-4 hours; repeated dosages within24 hours does not prolong response time. (Brooks 1994)
Cats: To help differentiate central diabetes insipidus from the nephrogenic form: 1 drop into theconjunctival sac twice daily for 2-3 days; a dramatic reduction in water intake or a 50%or greater increase in urine concentration gives strong evidence for a deficit in ADHproduction.
