How does IN DDAVP work?
Intranasal desmopressin, or IN DDAVP, is a medicine that helps stop bleeding in patients with von Willebrand disease, platelet function defects, and mild hemophilia A. These bleeding problems are caused by low amounts of clotting proteins in the blood or because platelets don’t work well. IN DDAVP helps release more proteins and helps platelets stick together. Then a blood clot can form and bleeding will stop.
The medicine starts to work about 30 minutes after it is given. It has the greatest effect in 1 to 3 hours. The effect may last 8 to 12 hours or longer.
Patients with heart problems or a history of blood clots should not use IN DDAVP.

3. Tilt the bottle so the tube inside the bottle is in the medicine.
4. Before using the medicine for the first time, prime it by pumping it into the air. Do this about 3 or 4 times. Point bottle away from face when priming.
