Key points below

What is DDAVP?

DDAVP is a medicine to help stop or prevent bleeding in patients with bleeding problems.   These bleeding problems are caused by problems with clotting. DDAVP helps release more clotting proteins and helps platelets stick together. Then a blood clot can form where needed and bleeding will stop. Patients with heart problems or a history of blood clots should not get DDAVP.
