3 HOW TO TAKE Desmopressin Spray
1 WHAT Desmopressin Spray IS AND
Desmopressin Spray contains the active ingredient
desmopressin which belongs to a group of medicines
called “posterior pituitary lobe hormones, vasopressin
and analogues”. Desmopressin is very similar to a
natural hormone in the body which can reduce the
amount of urine that the body produces.
Desmopressin Spray is used to treat diabetes insipidus;
this is a condition which causes extreme thirst and the
production of large volumes of dilute urine.
Desmopressin Spray can also be used to test how well
your kidneys are working.

Desmopressin Spray should only be used by the nasal
route. Always take Desmopressin Spray exactly as your
doctor has told you. You should check with your doctor
or pharmacist if you are not sure. The usual doses are
given below.

Treatment of diabetes insipidus
Adults: 1 or 2 sprays each day (when taking 2 sprays
use a different nostril for each spray).
Children and Adolescents below 18 years: 1 spray
each day.
Your doctor may increase the dose to 4 sprays each day
(taken as one spray into each nostril, in the morning and
at bedtime).
