A 6-year-old boy is brought to the pediatrician by his parents due to recent bedwetting. He was toilet-trained at the age of 3 and has been able to stay dry during the day. However, he continues to have nighttime “accidents” 3-4 times per week. The patient consumes fluids in the morning and afternoon, but not prior to bed. The family recently moved from their home in the city to a suburban neighborhood, and he has experienced difficulty making new friends at school. Temperature is 37.2°C (99.0°F), blood pressure is 107/68 mmHg, and pulse is 79/min. A complete physical examination is noncontributory. The patient is subsequently trialed on scheduled timed voids overnight and a bedwetting alarm, both of which fail to control his symptoms. The patient is subsequently initiated on a medication that acts as an antidiuretic hormone analog. Which of the following medications was most likely prescribed?
Enuresis is a condition characterized by the inability to control urination. It can either be daytime (while awake) or nighttime (during sleep). The cause of enuresis can be anything from psychological problems to physical abnormalities, and it can occur in people of any age.
