Ddavp

Central Diabetes Insipidus DDAVP Tablets are indicated as antidiuretic replacement therapy in the management of central diabetes insipidus and for the management of the temporary polyuria and polydipsia following head trauma or surgery in the pituitary region. DDAVP is ineffective for the treatment of nephrogenic diabetes insipidus. Patients were selected for therapy based on the diagnosis by means of the water deprivation test, the hypertonic saline infusion test, and/or response to antidiuretic hormone.

Continued response to DDAVP can be monitored by measuring urine volume and osmolality. Primary Nocturnal Enuresis DDAVP Tablets are indicated for the management of primary nocturnal enuresis. DDAVP may be used alone or as an adjunct to behavioral conditioning or other non-pharmacologic intervention.

DDAVP Tablets are contraindicated in individuals with known hypersensitivity to desmopressin acetate or to any of the components of DDAVP Tablets. DDAVP is contraindicated in patients with moderate to severe renal impairment (defined as a creatinine clearance below 50 mL/min). DDAVP is contraindicated in patients with hyponatremia or a history of hyponatremia.

1. Very rare cases of hyponatremia have been reported from world-wide postmarketing experience in patients treated with DDAVP (desmopressin acetate). DDAVP is a potent antidiuretic which, when administered, may lead to water intoxication and/or hyponatremia. Unless properly diagnosed and treated hyponatremia can be fatal. Therefore, fluid restriction is recommended and should be discussed with the patient and/or guardian.

Careful medical supervision is required. 2. When DDAVP Tablets are administered, in particular in pediatric and geriatric patients, fluid intake should be adjusted downward to decrease the potential occurrence of water intoxication and hyponatremia. (See PRECAUTIONS, Pediatric Use and Geriatric Use .) All patients receiving DDAVP therapy should be observed for the following signs of symptoms associated with hyponatremia: headache, nausea/vomiting, decreased serum sodium, weight gain, restlessness, fatigue, lethargy, disorientation, depressed reflexes, loss of appetite, irritability, muscle weakness, muscle spasms or cramps and abnormal mental status such as hallucinations, decreased consciousness and confusion.
