☀️ Medications and Bedwetting
The most commonly prescribed medication for bedwetting is DDAVP (desmopressin), known in some countries by the brand name Minirin. DDAVP is a synthetic version of vasopressin, the hormone that signals the kidneys to produce less urine. By giving the child this hormone at bedtime, urine production drops and the bladder is less likely to overflow during sleep.
DDAVP can be useful in specific situations, most notably for occasional dry nights at sleepovers or camp. However, it has serious limitations as a long-term solution. First, it suppresses the symptom without teaching the brain anything. When the medication is stopped, 60 to 90% of children relapse. Second, fluid intake must be carefully controlled in the hours before bedtime; otherwise, the child risks water intoxication. Third, the medication requires ongoing prescriptions and parental supervision.
For most families, the better long-term path is behavioural treatment with a bedwetting alarm. The goal is not to mask the problem but to resolve it.
