Medication acts as a "bandaid" in that it does not cure bedwetting, but may give temporary relief.

The most acceptable drug in use is desmopressin. The active ingredient is a synthetic analogue of the anti-diuretic hormone (ADH), normally produced by the body.

It acts on the kidneys, reducing or preventing urine production for a period of time.

Generally side effects are mild, although a potentially serious one is hyponatremia. Because the body cannot produce urine during the 4-8 hours of drug action, it is important to minimise fluid intake once the drug is taken.  You thus need to ensure your child has adequate fluid intake during the day.

Desmopressin has an effect on about 60% of bedwetters, to varying extents.

Medication has a role in bedwetting:

(1) For short term use such as overnight stays, school camps, etc

(2) When alarm treatment has been unsuccessfully attempted at least two times over two years.

Relapse

Wetting usually resumes immediately on stopping the medication
