About Guanfacine for ADHD 

Guanfacine is prescribed to treat attention deficit hyperactivity disorder (ADHD). The brand name of Guanfacine is called Intuniv. ADHD medications like guanfacine are typically used a part of an overall treatment plan.

Guanfacine interacts with the brain's receptors resulting in improved memory recall, reduced diversion, and improved impulsive control. As a result, it also reduces nerve impulses in heart and blood vessels. It is not a stimulant.

Intuniv is only available by prescription. Intuniv's generic name is guanfacine. It belongs to the family of drugs known as alpha-2 adrenergic agonists. It is available under brand names such as Guanfacine XR, guanfacine, Tenex, and Intuniv.
