DDAVP (desmopressin) comes in tablet form and is taken orally with a glass of water. The directions on the prescription label should be followed closely, and the medicine should be taken at regular intervals and not more often than directed. Taking the medicine more frequently than prescribed can lead to serious side effects.
The dosage for desmopressin will depend on your medical condition and response to treatment. Taking more desmopressin than prescribed or taking it more often than prescribed can lead to serious side effects, so it is important to follow your doctor’s instructions closely.
Patients should begin taking desmopressin at a dose of 0.05 mg (1/2 of the 0.1 mg tablet) two times a day, and the dose should be adjusted individually to achieve their optimal therapeutic dose. The optimal dosage range is 0.1 mg to 0.8 mg daily, divided into two or three doses depending on the patient’s need for antidiuresis. The total daily dosage can be increased or decreased in the range of 0.1 mg to 1.2 mg, divided into two or three separate doses as needed.
