What is Intuniv (Guanfacine)

Guanfacine is a sympatholytic drug used to treat hypertension and attention deficit hyperactivity disorder. This medication is used to treat attention deficit hyperactivity disorder (ADHD), as part of a total treatment plan including psychological, educational, and social measures. Unlike other drugs used to treat ADHD, guanfacine is not a stimulant. The exact way that guanfacine works to treat ADHD is unknown. Attention deficit/hyperactivity disorder (ADHD) is one of the most common childhood diagnoses. Symptoms, which can continue through adolescence and adulthood, include difficulties in staying focused, paying attention, controlling behavior, and managing hyperactivity or overactivity.1 Children with ADHD may struggle with low self-esteem, troubled relationships, and poor performance in school.

When used together with a stimulant, the usual daily recommended dose is not more than 4 mg. Swallow the tablets whole with a full glass of water. Do not break, crush or chew the tablet. This will affect how INTUNIV works. Do not take a double dose to make up for the missed dose. For children 6 to 17 years of age with ADHD, the starting dose of guanfacine ER is 1 mg once daily; this amount may be increased in increments of 1 mg/week, up to 4 mg, the recommended maximum daily dose . Optimal dose is not established. Limited data suggest 0.25 to 2 mg/day PO, given in divided doses, may have a beneficial effect. In a small crossover study, 17 adult patients were treated for 2 weeks with each guanfacine, dextroamphetamine, and placebo with a 4-day washout period between treatments. Guanfacine was initiated at 0.25 mg/day PO once daily in the morning and was increased by 0.25 mg/day or every other day as tolerated. Max: 2 mg/day PO; the mean (SD) daily dose was 1.1 mg (0.6 mg).
