DDAVP (which stands for 1-deamino-8-D-arginine vasopressin) is an oral tablet made up of antidiuretic hormone called desmopressin. We carry the brand choice DDAVP in 0.1mg and 0.2mg.

DDAVP (Desmopressin) is a man made form of vasopressin (a natural hormone found in the pituitary gland) which has an effect on various body functions such as affecting blood pressure, kidney function, and regulating how the body uses water. When the body doesn’t have enough vasopressin, your kidneys may excrete an extra amount of water; this will cause a high frequency in needing to urinate, dehydration, and can even cause low blood pressure.

In conditions like diabetes insipidus (“water diabetes”) and in certain cases of head injury or brain surgery, the body does not produce enough vasopressin. DDAVP is prescribed to patients with those conditions to replace the loss vasopressin with desmopressin to control their possible excessive thirst and urination due to the condition. DDAVP works to treat these conditions by increasing the water permeability (how easily liquid and gas passes through something) in the renal tubular cells, decreasing the urine volume and increasing the urine concentration. This also helps decrease the chance of dehydration. DDAVP is also prescribed to those who cannot control their nighttime bedwetting.

DDAVP comes in other forms such as DDAVP Nasal Spray and DDAVP Melt (oral).
