- American Regent recalled 17 lots of vasopressin in August, 2011 due to potential for decreased potency.
- JHP has Pitressin on shortage due to increased demand for the product.3
- APP had vasopressin on shortage due to increased demand for the product.4

Implications for Patient Care
- Vasopressin is an unapproved drug. Vasopressin injection is a synthetic 8-arginine vasopressin, an antidiuretic hormone released from the posterior pituitary gland. Vasopressin injection is labeled for 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.5,6,7
- Unlabeled uses of vasopressin include adjunctive treatment of gastrointestinal or esophageal variceal hemorrhage, pulseless cardiac arrest, vasodilatory or septic shock, and for donor management in brain-dead patients.6,7,8
- To avoid dosing errors, be aware that vasopressin is dosed in units and desmopressin is dosed in micrograms.5,9
- Vasopressin and desmopressin have different indications and actions.5,7,9
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.9
- 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.7
- 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.10 Institutions may want to consider conserving product for this indication.
