Desmopressin Tablets

Desmopressin is a synthetic form of the vasopressin hormone. This hormone regulates the water balance in your body. Desmopressin treats central diabetes insipidus and bed-wetting by reducing frequent urination and excessive thirst. The brand name of this medication is DDAVP®.

What is this medication?

DESMOPRESSIN (des moe PRESS in) treats conditions that cause the body to make too much urine, such as diabetes insipidus and nocturnal polyuria. It works by helping your kidneys make less urine, which balances the levels of fluid and salt in your body. This decreases symptoms such as thirst and frequent need to urinate.
