Description
Indications
Desmopressin is utilized to regulate the volume of urine produced by the kidneys. The secretion of urine is under the control of vasopressin, a specific substance present in the body. In individuals suffering from conditions such as diabetes insipidus, head injuries or brain surgery. In such cases, desmopressin, an artificial analog of vasopressin, is administered to compensate for the depleted levels. This medication aids in managing excessive thirst and urination caused by these conditions, as well as preventing dehydration. Desmopressin is employed to regulate nocturnal enuresis in children by reducing urine frequency and minimizing bedwetting incidents.
Uses and Dosage
To manage diabetes insipidus, take this medication orally, typically two to three times per day- or as per your physician’s instructions.
For bedwetting management, take this medication orally once daily before bedtime. Children should restrict fluid intake after dinner, specifically 1 hour before taking desmopressin until the following morning or at least 8 hours after the dose. In case your child wakes up during the night, control their liquid consumption.
Limit fluid intake, particularly for children and older individuals, when taking desmopressin. If you realize that you are consuming more fluids than prescribed, inform your doctor immediately to adjust your treatment plan.
Dosage is determined based on your medical condition and the response to treatment. Do not exceed the prescribed dosage or take it more frequently than advised.
To achieve maximum benefit, take this medication consistently at the same time(s) each day. Remember to take it regularly.
