Adjunctive effects on serotonin and -aminobutyric acid receptors also assist in treating insomnia in children with attention-deficit/hyperactivity disorder. Guanfacine (Intuniv) is an extended-release, noncentral nervous system stimulant approved for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children six to 17 years of age; however, it appears to be most effective in children 12 years or younger. (2014). Dosing should be initiated with one 0.1 mg tablet at bedtime and titrated by 0.1 mg in weekly intervals until the desired response is achieved (Table 2).

ADHD-RS IV scores at study completion showed a statistically significant decrease in the GXR group (16.7 points) compared with placebo (8.9 points; p<0.0001). These rates are similar to what has been reported in the prescribing information for immediate release guanfacine, with 39% of patients taking a 3 mg dose reporting somnolence.11 Fatigue was also a common adverse effect in the GXR study, affecting 3.5% of patients in the placebo group compared to over 20% in the GXR 3 mg group.13 These rates of fatigue may be higher than what has been reported for the immediate release formulation, with only 10% of patients reporting this side effect in initial dose-response studies of patients with hypertension.11, A study conducted by Sallee and colleagues examined the use of GXR in 324 patients 6 to 17 years of age over a 25-month time period.
