Quillivant XR (methylphenidate hydrochloride) is a central nervous system (CNS) stimulant used to treat Attention Deficit Hyperactivity Disorder (ADHD). Quillivant XR is available in generic form. Common side effects of Quillivant XR include decreased appetite, insomnia, nausea, vomiting, upset stomach, abdominal pain, weight loss, anxiety, dizziness, irritability, quickly changing moods, tics, eye pain, rash, the urge to scratch your skin, increased heart rate, and increased blood pressure. Quillivant XR has a high potential for abuse and dependence.

For patients 6 years of age and above, the recommended starting dose of Quillivant XR is 20 mg given orally once daily in the morning with or without food. The dosage may be increased weekly in increments of 10 mg to 20 mg per day. A daily dosage above 60 mg is not recommended. Quillivant XR may interact with monoamine oxidase inhibitors (MAOIs). The effects of Quillivant XR have not been studied in pregnant women. Undesirable pregnancy outcomes such as premature delivery and low birth weight have been seen in mothers dependent on stimulant products such as amphetamines. Nursing mothers should discontinue Quillivant XR or discontinue nursing.

Quillivant XR FDA Prescribing Information: Side Effects
(Adverse Reactions)


Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Clinical Trials Experience With Other Methylphenidate Products In Children, Adolescents, And Adults With ADHD

Commonly reported ( ≥ 2% of the methylphenidate group and at least twice the rate of the placebo group) adverse reactions from placebo-controlled trials of methylphenidate products include: appetite decreased, weight decreased, nausea, abdominal pain, dyspepsia, dry mouth, vomiting, insomnia, anxiety, nervousness, restlessness, affect lability, agitation, irritability, dizziness, vertigo, tremor, blurred vision, blood pressure increased, heart rate increased, tachycardia, palpitations, hyperhidrosis, and pyrexia.

Clinical Trials Experience With QUILLIVANT XR In Children And Adolescents With ADHD

There is limited experience with QUILLIVANT XR in controlled trials. Based on this limited experience, the adverse reaction profile of QUILLIVANT XR appears similar to other methylphenidate extended-release products. The most common ( ≥ 2% in the QUILLIVANT XR group and greater than placebo) adverse reactions reported in the Phase 3 controlled study conducted in 45 ADHD patients (ages 6-12 years) were affect lability, excoriation, initial insomnia, tic, decreased appetite, vomiting, motion sickness, eye pain, and rash.
