⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Diabetes Insipidus: The daily dose is 2 mcg to 4 mcg administered as one or two divided doses by subcutaneous or intravenous injection. The dosage must be determined for each patient and adjusted according to the pattern of response. ( 2.1 ) Hemophilia A and von Willebrand’s Disease (Type I): 0.3 mcg/kg (to a maximum of 20 mcg) administered by intravenous infusion.
Dilute dose as appropriate. ( 2.1 ) See Full Prescribing Information for instructions on reconstitution, preparation, and administration ( 2 ).
2.1Pretreatment Testing and On-Treatment Monitoring Diabetes Insipidus Prior to treatment with Desmopressin Acetate, assess serum sodium, urine volume and osmolality. Intermittently during treatment, assess serum sodium, urine volume and osmolality or plasma osmolality. Hemophilia A Prior to treatment with Desmopressin Acetate Injection USP, verify that factor VIII coagulant activity levels are >5% and exclude the presence of factor VIII autoantibodies.
Also assess serum sodium and aPTT prior to treatment. In certain clinical situations, it may be justified to try Desmopressin Acetate in patients with factor VIII levels between 2% to 5%; however, these patients should be carefully monitored. von Willebrand’s Disease (Type I) Prior to treatment with Desmopressin Acetate Injection USP, verify that factor VIII coagulant activity levels are >5% and exclude severe von Willebrand’s disease (Type I) and presence of abnormal molecular form of factor VIII antigen. During treatment with Desmopressin Acetate Injection USP, assess serum sodium, bleeding time, factor VIII coagulant activity, ristocetin cofactor activity, and von Willebrand antigen to ensure that adequate levels are being achieved.
For All Patients Receiving Repeated Doses: Restrict free water intake and monitor for hyponatremia. Ensure that serum sodium is normal prior to initiating or resuming treatment with Desmopressin Acetate Injection USP.
2.2Recommended Dosage Initiate fluid restriction during treatment with Desmopressin Acetate Injection USP [see Warning and Precaution (5.1) , Use in Specific Populations (8.4, 8.5) ] . Diabetes Insipidus: Treatment naïve patients: The recommended starting daily dosage is 2 mcg to 4 mcg administered as one or two divided doses by subcutaneous or intravenous injection. Do not dilute Desmopressin Acetate Injection USP for the Diabetes Insipidus population.
The morning and evening doses should be separately adjusted for an adequate diurnal rhythm of water turnover. Adjust dose based upon response to treatment estimated by two parameters: adequate duration of sleep and adequate, not excessive, water turnover. Patients changing from intranasal desmopressin: The recommended starting dose of Desmopressin Acetate Injection USP is 1/10 th the daily maintenance intranasal dose administered by subcutaneous or intravenous injection as one or two divided doses.
Hemophilia A and von Willebrand’s Disease (Type I): The recommended dosage is 0.3 mcg/kg actual body weight (to a maximum of 20 mcg) administered by intravenous infusion over 15 minutes to 30 minutes. If used preoperatively, administer 30 minutes prior to the procedure. If used to reduce spontaneous or traumatic bleeding, doses may be repeated after 8 hours to 12 hours and once daily thereafter, if needed, based upon clinical condition and von Willebrand factor and factor VIII levels.
The necessity for repeat administration of Desmopressin Acetate or use of any blood products for hemostasis should be determined by laboratory response as well as the clinical condition of the patient. Tachyphylaxis (lessening of response) with repeated administration (i.e., given more frequently than every 48 hours) may occur. The initial response is reproducible if Desmopressin Acetate is administered every 2 to 3 days.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pediatric Use: Initiate fluid intake restriction to prevent possible hyponatremia and water intoxication. ( 8.4 ) Geriatric Use: Carefully select dose and monitor renal function more frequently. ( 8.5 )
8.1Pregnancy Risk Summary Prolonged experience with Desmopressin Acetate Injection USP in pregnant women over several decades, based on the available published literature and case reports, have not identified a drug associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In addition, in vitro studies with human placenta demonstrate poor placental transfer of desmopressin. No adverse developmental outcomes were observed in animal reproductive and developmental studies following administration of desmopressin acetate during organogenesis to pregnant rats and rabbits, at doses 130- and 110- times, respectively, the recommended dose of 18 mcg for a 60 kg patient, based on body surface area (mg/m 2 ).
The estimated background risk of major birth defects and miscarriage for the indicated population are unknown. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Disease Associated Maternal and Embryo-fetal Risk: Pregnant women with Hemophilia A or von Willebrand’s disease may be at an increased risk for bleeding diatheses and hemorrhagic events at delivery.
An affected newborn may also be at risk of bleeding diatheses. Data Animal Data In a developmental toxicity study in rats, desmopressin acetate was administered intravenously at doses of 9.68, 48.4, or 241 mcg/kg/day during the period of organogenesis (gestations days 7 to 17). Laparohysterectomy for fetal examinations were conducted on gestation day 20 for twenty females in each group; the remaining 10 females were allowed to litter in order to determine any postnatal effects that might be attributable to pre-natal treatment.
No effects were seen on maternal and fetal survival, growth and morphology or post-natal offspring survival, growth, development, behavior and reproductive performance up to 241 mcg/kg/day (130 times the 18 mcg dose received by a 60 kg patient based on body surface area). In an embryo-fetal development study and a pre- and postnatal development study in rabbits, desmopressin acetate was administered subcutaneously at doses of 2, 20 or 200 mcg/kg/day (embryo-fetal development) and 0.1, 1 or 10 mcg/kg/day (pre- and postnatal development) during the period of organogenesis (gestation days 6 to 18).
No effects on maternal and fetal survival or morphology were observed in both studies at doses of up to 200 mcg/kg/day (215x the 18 mcg dose received by a 60 kg patient based on body surface area) nor were there effects in the pre- and postnatal development study on parturition, postnatal survival, growth, development or behavior, up to the highest dose tested of 10 mcg/kg/day (11 times the 18 mcg dose received by a 60 kg patient, based on body surface area).
8.2Lactation Risk Summary Breastfeeding is not expected to result in clinically relevant exposure of the infant to desmopressin following maternal administration. Desmopressin is poorly transferred into human breastmilk at negligible amounts ( see Data ). There is no information on the effects of desmopressin on the breastfed child or on milk production.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Desmopressin Acetate Injection USP and any potential adverse effects on the breastfed child from Desmopressin Acetate Injection USP or from the underlying maternal condition. Data The breast milk of lactating women was collected over 8 hours following administration of 300 mcg desmopressin nasal spray. The expected area under the plasma concentration time curve (AUC) of desmopressin following 300 mcg nasal spray is 2.4-fold higher to t…
🆘 Overdosage ▾
10 OVERDOSAGE Overdosage of Desmopressin Acetate Injection USP leads to prolonged duration of action with an increased risk of water retention and hyponatremia. Signs of overdose may include headaches, abdominal cramps, nausea, facial flushing, confusion, drowsiness, problems with passing urine and rapid weight gain due to fluid retention [see Warnings and Precautions (5.1) ] . In case of overdosage, the dosage should be reduced, frequency of administration decreased, or the drug withdrawn according to the severity of the condition, serum sodium assessed, and hyponatremia treated appropriately.
There is no known specific antidote for desmopressin acetate or Desmopressin Acetate Injection USP 4 mcg/mL.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Desmopressin acetate increases plasma levels of factor VIII activity in patients with hemophilia and von Willebrand’s disease Type I. The antidiuretic effects of desmopressin acetate are mediated by stimulation of vasopressin 2 (V2) receptors, thereby increasing water re-absorption in the kidney, and hence reducing urine production. Desmopressin acetate is a replacement hormone for antidiuretic hormone in the treatment of central diabetes insipidus.
The change in structure of arginine vasopressin to desmopressin acetate resulted in increased duration of action and a decreased vasopressor action and decreased actions on visceral smooth muscle relative to the enhanced antidiuretic activity, so that clinically effective antidiuretic doses were usually below threshold levels for effects on vascular or visceral smooth muscle.
12.2Pharmacodynamics The response to Desmopressin Acetate of factor VIII activity and plasminogen activator is dose-related, with maximal plasma levels of 300 to 400 percent change from baseline obtained after infusion of 0.4 mcg/kg. The increase of factor VIII is rapid and evident within 30 minutes, reaching a maximum at a point ranging from 90 minutes to two hours. The duration of the hemostatic effect depends on the half-life for VIII:C which is about 8-12 hours.
The percentage increase of factor VIII levels in patients with mild hemophilia A and von Willebrand’s disease was not significantly different from that observed in normal healthy individuals when treated with 0.3 mcg/kg of Desmopressin Acetate infused over 10 minutes. The use of Desmopressin Acetate Injection USP in patients with central diabetes insipidus reduces urinary output, increases urine osmolality, and decreases plasma osmolality.
12.3Pharmacokinetics Elimination The geometric mean terminal half-life is 2.8 hours. Metabolism Desmopressin is not metabolized by human CYP450 system. Excretion After intravenous administration of 2 mcg, 52% of the dose was recovered in the urine within 24 hours as unchanged desmopressin.
Drug Interaction Studies In vitro studies in human liver microsome preparations have shown that desmopressin does not inhibit the human CYP450 system. No in vivo interaction studies have been performed with Desmopressin Acetate Injection USP. Specific Populations Patients with Renal Impairment A pharmacokinetic study was conducted in subjects with normal renal function and patients with mild, moderate, and severe renal impairment (n=24, 6 subjects each group) with a single 2 mcg dose of desmopressin acetate intravenous injection.
The geometric mean terminal half-life was 2.8 hours in subjects with normal renal function, and 4, 6.6, and 8.7 hours in patients with mild, moderate, and severe renal impairment, respectively. In patients with mild, moderate and severe renal impairment, mean desmopressin area under the plasma drug concentration time curve (AUC) was 1.5 fold, 2.4 fold and 3.6 fold higher, respectively compared to that of subjects with normal renal function.
