Quillivant XR Uses

How Does It Work?

Quillivant XR is a stimulant medication. While stimulants can cause hyperactivity, they appear to have a calming effect when used in the doses for ADHD. The exact way Quillivant XR produces a calming effect is unknown. What is known is that the medication affects certain chemical messengers in the brain known as neurotransmitters.
More specifically, Quillivant XR acts on the neurotransmitters dopamine and norepinephrine. Having too little of these neurotransmitters in certain areas of the brain is thought to lead to inattention, hyperactivity, and impulsive behavior -- the core symptoms of ADHD.
Quillivant XR works by increasing the amount of dopamine and norepinephrine in certain areas of the brain. This increase in dopamine and norepinephrine would be expected to cause hyperactivity and overstimulation; however, in people with ADHD (who may not have enough dopamine and norepinephrine), increasing dopamine and norepinephrine can improve focus and reduce hyperactive and impulsive behaviors.

Is It Safe for Children to Use Quillivant XR?

Quillivant XR is approved for use in children who are at least six years old. It is not approved for use in children younger than age six, as it has not been adequately studied in this age group. Talk to your healthcare provider about the benefits and risks of using the drug in young children.

Can Older Adults Use It?

Quillivant XR has not been adequately studied in adults older than 65 years old. Due to the cardiovascular risks associated with the medication, it may not be appropriate for some older adults.
