What is Quillivant XR?
Quillivant XR is approved by the FDA for the treatment of ADHD in persons aged six and older. It is the only liquid, extended-release methylphenidate product available. It is especially useful for the one-third of children who can't swallow pills and for people of any age who need very low doses of methylphenidate medication. Quillivant XR became available in January 2013.
How is Quillivant XR taken?
Quillivant XR is a liquid formulation that slowly releases methylphenidate (the molecule found in Ritalin and Concerta). Quillivant XR works in 45 minutes and keeps working for up to 12 hours after taking.*
The recommended starting dose of Quillivant XR for patients 6 years and above is 20 mg once daily in the morning. The dose may be titrated weekly in increments of 10 mg to 20 mg. Daily doses above 60 mg have not been studied and are not recommended. The medication is taken orally with a plastic syringe packaged with the medication.
Why would someone take Quillivant XR instead of another methylphenidate/ Ritalin product?
All side effects of stimulant medications occur when the medications are either entering the body or leaving the body at the end of the dose. The slower that blood levels change, the less likely that side effects will occur. People usually pay the extra money for extended-release formulations, such as Quillivant XR, because they are smoother (better tolerated).
Who should avoid this medication?
People with mild cases of hypertension should avoid Quillivant XR use until high blood pressure is well controlled. People with more serious heart conditions should consult their doctor, and perhaps a cardiologist, before starting Quillivant XR. Stimulant medications can trigger mania in people with bipolar disorder. People with a history of drug abuse should use extreme caution when taking this medication.
What are the side effects?
Based on accumulated data from other methylphenidate products, the most common (greater than or equal to 5% and twice the rate of placebo) adverse reactions are appetite decreased, insomnia, nausea, vomiting, dyspepsia, abdominal pain, weight decreased, anxiety, dizziness, irritability, affect lability, tachycardia, and blood pressure increased.
Is Quillivant XR addictive?
Quillivant XR has a high potential for misuse, abuse, and addiction, especially among people who do not have ADHD.
Quillivant XR is a "Schedule II Stimulant." What does that mean?
"Schedule II" is the classification used by the Drug Enforcement Agency to indicate drugs with a high potential for abuse. Other Schedule II drugs include the opiate painkillers and cocaine. The ADHD stimulants, amphetamine and methylphenidate, originally came on the market as over-the-counter decongestants, becoming prescription drugs in 1959. They were classified as controlled or "scheduled" medications in 1978. CHADD has petitioned the DEA several times for these medications to be returned to the least restrictive category of Schedule IV, but their request has so far been denied.

*In a clinical study, Quillivant XR was measured using the SKAMP-Combined score and found effective at 45 minutes, 2, 4 (primary endpoint), 8, 10, and 12 hours after taking. This study was performed in a laboratory classroom setting. At the end of each week, school teachers and raters used the SKAMP rating scale to evaluate the efficacy of Quillivant XR on changes in attention and behavior in children with ADHD aged 6 to 12 years.
