RT Journal Article SR Electronic T1 Oxybutynin for treatment of nocturnal enuresis in children JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 559 OP 561 VO 57 IS 5 A1 Bat-Chen Friedman A1 Boris Friedman A1 Ran D. Goldman YR 2011 UL http://www.cfp.ca/content/57/5/559.abstract AB Question A 7-year-old child and his parents visit my clinic owing to the child’s frequent bed-wetting. During the day, he has no problem controlling his urination. The family has tried behavioural methods but has failed to achieve dryness during the night. They ask to begin medical treatment. Is oxybutynin a safe and effective drug for treating nocturnal enuresis? Answer Oxybutynin is an anticholinergic drug that has not been proven to be effective for treatment of nocturnal enuresis not accompanied by daytime symptoms, such as urgency. It can be added as a second-line drug and is effective for treating children with both daytime and nighttime wetting. Nevertheless, its common adverse effects, which can involve the central nervous system, should be considered when deciding whether or not to use it, especially in young children.
