Intuniv (guanfacine ER — non-stimulant)

Overview: Intuniv (Guanfacine ER)

Intuniv (guanfacine ER) is an extended-release oral tablet prescribed to manage attention-deficit/hyperactivity disorder (ADHD) in children, adolescents, and sometimes adults. Unlike stimulant medications, Intuniv is a non-stimulant that works on specific receptors in the brain to help improve focus, attention, and impulse control.

Patients usually take Intuniv once daily, often in the morning or evening, depending on their doctor’s instructions. It may be used alone or in combination with stimulant medications when appropriate.

Uses of Guanfacine ER

What Is Intuniv Used For?

Intuniv helps manage ADHD symptoms by regulating brain activity that controls attention and behavior. Specifically, it:

• Reduces hyperactivity

• Improves focus and attention

• Decreases impulsive behaviors

Doctors may prescribe Intuniv for other conditions when they determine it is medically necessary, such as anxiety or sleep disturbances linked to ADHD. Patients should always follow their healthcare provider’s instructions.

How Intuniv Works

Mechanism of Action

Intuniv works differently from stimulants. It targets alpha-2 adrenergic receptors in the brain. By stimulating these receptors, Intuniv helps improve the brain’s ability to regulate attention, emotional responses, and behavior.

Over time, many patients notice better focus, reduced hyperactivity, and calmer, more controlled behavior.
