Minirin Melt contains desmopressin, which acts similarly to the natural antidiuretic hormone of the pituitary gland, arginine vasopressin. Desmopressin is characterized by a significantly prolonged antidiuretic effect (reducing urine production) and a complete lack of vasoconstrictive effect at therapeutic doses. Minirin Melt is used to treat:

• central diabetes insipidus;
• primary nocturnal enuresis in children over 6 years of age with normal urine concentrating ability;
• nocturia in adults associated with nocturnal polyuria (the volume of urine produced at night exceeds the bladder capacity).

• if you have moderate or severe renal impairment with a creatinine clearance below 50 ml/min;
