Reason for the Shortage
- American Regent has vasopressin injection on shortage due to manufacturing delays.1,2

- Par Sterile Products introduced Vasostrict injection in November 2014. This is the only FDA-approved vasopressin injection.3
- Fresenius Kabi has vasopressin on shortage due to increased demand for the product.4
Vasostrict Injection, Par Sterile Products3
20 units/mL, 1 mL multi-dose vial, 25 count (NDC 42023-0164-25)
Estimated Resupply Dates
- American Regent has vasopressin 20 units/mL 0.5 mL, 1 mL, and 10 mL vials on back order and the company cannot estimate a release date.1,2
- Fresenius Kabi has vasopressin injection on intermittent back order and the company is releasing product as it becomes available.4
Implications for Patient Care
- Vasopressin injection is a synthetic 8-arginine vasopressin, an antidiuretic hormone released from the posterior pituitary gland. Vasopressin injection (Vasostrict®) is FDA-labeled to increase blood pressure in adults with vasodilatory shock who have low blood pressure despite therapy with fluids and catecholamines.5
- Indications for unapproved vasopressin injection products include use in diabetes insipidus, for the prevention and treatment of postoperative abdominal distention, and to dispel gas that may interfere with interpretation of abdominal roentgenography.6,7,8
- Unlabeled uses of vasopressin include adjunctive treatment of gastrointestinal or esophageal variceal hemorrhage, pulseless cardiac arrest, and for donor management in brain-dead patients.7,8,9
- According to the product labeling, Vasostrict injection must be refrigerated (store between 2° and 8°C).5 A letter from Par Pharmaceuticals, Inc. states Vasostrict injection is stable for up to 90 days at room temperature (15° and 25°C) once the unopened vial is removed from refrigeration. Label the vial with the revised expiration date to prevent the medication from being used beyond the 90-day period. However, if the manufacturer’s original expiration date is shorter than the revised expiration date, use the shorter date. This information is based on extrapolated data.19
- To avoid dosing errors, be aware that vasopressin is dosed in units and desmopressin is dosed in micrograms.5,6,10
- Vasopressin and desmopressin have different indications and actions.5,8,10
Alternative Agents & Management
- Desmopressin acetate (DDAVP) is another antidiuretic peptide available in the US. Desmopressin is labeled for treatment of diabetes insipidus, primary nocturnal enuresis, Hemophilia A, and von Willebrand disease.10
- Desmopressin acetate has greater vasopressin receptor V2 selectivity compared with vasopressin and has greater anti-diuretic potency. However, desmopressin has less vasopressin receptor V1 activity, which results in lower vasopressor and smooth muscle contracting activity compared to vasopressin. Desmopressin increases Factor VIII activity to a greater degree than vasopressin in patients with hemophilia A or von Willebrand Disease.8
- Table 1 lists alternatives to vasopressin in specific situations.
- Vasopressin is used as hormone replacement therapy in brain-dead patients who are organ donors. Vasopressin is part of the United Network for Organ Sharing (UNOS) standardized donor management protocol.11 Institutions may want to consider conserving product for this indication.
