Vasostrict (Vasopressin) is a prescription medication used for the treatment of diabetes insipidus. This condition is caused by a lack of a naturally occurring pituitary hormone in the body. This medication is also used to treat or prevent certain conditions of the stomach after surgery or during abdominal x-rays. Vasopressin is also used to treat cardiac arrest. Vasopressin is a man-made form of the “anti-diuretic hormone” that is normally secreted by the pituitary gland. This medication acts on the kidneys and blood vessels. Vasopressin works by preventing loss of water from the body by reducing urine output and helping kidneys reabsorb water into the body. This medication also raises blood pressure by narrowing blood vessels. Vasostrict is injected into a muscle or under the skin, or into a vein through an IV. The dose of Vasopressin is determined by the patient’s condition and response to the medication.
