1 INDICATIONS AND USAGE Desmopressin acetate injection is a vasopressin analog used for: Central Diabetes Insipidus - as antidiuretic replacement therapy in the management of central (cranial) diabetes insipidus and for the management of the temporary polyuria and polydipsia following head trauma or surgery in the pituitary region.

( 1.1 ) Hemophilia A- for patients with factor VIII coagulant activity levels greater than 5% to maintain hemostasis during surgical procedures and postoperatively or reduce bleeding with episodes of spontaneous or traumatic injuries such as hemarthroses, intramuscular hematomas, or mucosal bleeding.

( 1.2 ) von Willebrand’s disease (Type I) - for patients with mild to moderate disease with factor VIII levels greater than 5% to maintain hemostasis during surgical procedures or traumatic injuries such as hemarthroses, intramuscular hematomas, or mucosal bleeding.

( 1.3 ) Limitations of Use Desmopressin acetate is ineffective and not indicated for the treatment of nephrogenic diabetes insipidus.

( 1.3 ) von Willebrand’s disease (severe Type I) - not indicated for the treatment of patients with severe Type I von Willebrand’s disease and when there is evidence of an abnormal molecular form of factor VIII antigen.

( 1.3 ) 1.1 Central Diabetes Insipidus Desmopressin acetate injection is indicated as antidiuretic replacement therapy in the management of central (cranial) diabetes insipidus and for the management of the temporary polyuria and polydipsia following head trauma or surgery in the pituitary region.

Limitations of Use: Desmopressin acetate is ineffective and not indicated for the treatment of nephrogenic diabetes insipidus.

1.2 Hemophilia A Desmopressin acetate injection is indicated for patients with hemophilia A with factor VIII coagulant activity levels greater than 5% without factor VIII antibodies to: Maintain hemostasis during surgical procedures and postoperatively Reduce bleeding with episodes of spontaneous or traumatic injuries such as hemarthroses, intramuscular hematomas, or mucosal bleeding.

1.3 von Willebrand’s Disease Desmopressin acetate injection is indicated for patients with mild to moderate von Willebrand’s disease (Type I) with factor VIII levels greater than 5% to: Maintain hemostasis during surgical procedures and postoperatively Reduce bleeding with episodes of spontaneous or traumatic injuries such as hemarthroses, intramuscular hematomas, or mucosal bleeding.

Limitations of Use Desmopressin acetate is not indicated for the treatment of severe von Willebrand’s disease (Type I) and when there is evidence of an abnormal molecular form of factor VIII antigen [see Warnings and Precautions (5.2)].

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Hyponatremia [see Contraindications, Warnings and Precautions (5.1)] Hypotension and Hypertension [see Warnings and Precautions (5.2)] Increased risk of thrombosis in patients with von Willebrand’s Disease Type IIB [see Warnings and Precautions (5.3)] Hypersensitivity reactions [see Warnings and Precautions (5.4)] Fluid retention [see Warnings and Precautions (5.5)] The following adverse reactions have been identified during post-approval use of desmopressin acetate injection.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Cardiovascular: Hypertension, hypotension, tachycardia, thrombotic events, fluid retention Digestive: Nausea, abdominal cramps Immune: Hypersensitivity reactions Integumentary: Erythema, swelling, burning pain, facial flushing Laboratory: Hyponatremia Nervous: Headache, hyponatremic seizures Common adverse reactions are abdominal cramps, burning pain, erythema, facial flushing, fluid retention, headache, hypersensitivity reactions, hypertension, hyponatremia, hyponatremic seizures, hypotension, nausea, swelling, tachycardia, and thrombotic events.
