Vasopressin

Vasopressin is used in the treatment of diabetes insipidus, bleeding esophageal varices (bleeding from dilated veins in the food pipe leading to your stomach), and low blood pressure. Vasopressin is given by a healthcare professional. You should not self-administer this medicine at home. Your doctor will decide the dose and how often you should take them. Using this medicine can cause some common side effects such as headache, slow heart rate, high blood pressure, and low blood pressure. Let your doctor know if any of these side effects do not go away or get worse. Before using this medicine, inform your doctor if you have any problems with your heart, liver, or kidneys. You should also tell your doctor all the other medicines you are taking. This medicine is not recommended for children and adolescents. Vasopressin have the same structure as that of the natural hormone vasopressin. Vasopressin lowers the amount of urine and bleeding by constricting (narrowing) the blood vessels which, in turn, prevents the loss of water from the body.

• Bleeding esophageal varices • Diabetes insipidus • Low blood pressure

Vasopressin is a posterior pituitary hormone which may be synthetically prepared or extracted from animals. It exerts direct antidiuretic action on the kidneys by increasing tubular reabsorption of water. Vasopressin also acts by constricting the peripheral blood vessels and causes the smooth muscle of the intestine, gall bladder and urinary bladder to contract. Vasopressin is given parenterally or intranasally in the form of argipressin or lypressin. Argipressin is a synthetic type of vasopressin derived from most mammals (including man but excluding pig) while lypressin is vasopressin from pig.

Adult Dose: Intravenous Initial control of variceal bleeding Adult: 20 units in 100 ml of glucose 5% infused over 15 min. Parenteral Cranial diabetes insipidus Adult: 5-20 units SC/IM every 4 hr. Abdominal Distention Adult: 5 units IM initially; repeated q3-4hr PRN; may be increased to 10 units Hepatic impairment: Lower doses may be required to achieve response

Hypersensitivity. Vascular disease especially coronary artery disease; chronic nephritis (until reasonable blood-nitrogen conc attained).

Carbamazepine, chlorpropamide, clofibrate, urea, fludrocortisone and tricyclic antidepressants may potentiate the antidiuretic action of vasopressin. Demeclocycline, noradrenaline, lithium, heparin and alcohol may decrease antidiuretic action of vasopressin. Ganglionic blockers may increase sensitivity to the pressor effect of vasopressin. Increased risk of QT prolongation with dolasetron.

[UNSAFE] It is unsafe to consume alcohol with Vasopressin.
