Diabetes Insipidus - How often do you use the DDAVP spray to control voiding. And how many sprays?

10 Feb 2010

The dosage must be determined for each individual patient depending on response.
The usual dosage range in adults is 0.1 to 0.4 mL daily, either as a single dose or divided into two or three doses. Most adults require 0.2 mL daily in two divided doses (morning and night)

The nasal spray pump can only deliver doses of 0.1 mL (10 mcg) or multiples of 0.1 mL. The spray pump must be primed prior to the first use. To prime pump, press down four times. The bottle will now deliver 0.1ml (10 mcg) of drug per spray every spray thereafter (after 50 sprays the bottle should be discarded)
Hope this helps.
