Polyuria after discontinuation of methylphenidate treatment in a child with ADHD

Abstract

Attention deficit hyperactivity disorder (ADHD) is characterized by impairing inattention, hyperactivity, and impulsivity. Stimulants, including methylphenidate (MPH) are commonly used for its management.MPH has been reported to improve nocturnal enuresis among children with ADHD previously, although there were also reports of enuresis associated with its use. Here we report a case of polyuria probably related with MPH discontinuation. Regardless of its mechanism clinicians should be aware of polyuria after cessation of MPH treatment.
