Enurex 200 mcg is a prescription medicine containing Desmopressin Acetate, a synthetic analogue of the natural antidiuretic hormone (ADH). It is primarily used to treat central diabetes insipidus, primary nocturnal enuresis (bedwetting) in children and adults, and nocturia (frequent urination at night). Enurex works by helping the kidneys conserve water, thus reducing urine production—especially overnight.
