ROCKVILLE, Md., Aug. 31, 2026 (GLOBE NEWSWIRE) -- Professional snowboarder, Chloe Kim, is partnering with Supernus Pharmaceuticals as a compensated ambassador to discuss her journey with attention-deficit/hyperactivity disorder (ADHD) and her treatment plan with Qelbree (viloxazine extended-release capsules), a once-daily, non-stimulant medication for patients 6 years and older. Designed for flexible once-a-day routine integration, Qelbree offers 24-hour medication exposure, no evidence of abuse potential, and versatile administration options, including the ability to be sprinkled and taken at any time of day (either morning or night). Through this partnership, Chloe Kim will open up about her own diagnosis to challenge misconceptions about ADHD. By sharing her lived experience, she will encourage others to advocate for their health and initiate collaborative conversations with their doctors about a potential treatment plan.

“Teaming up with Supernus to share my personal experience with ADHD is about turning my diagnosis into advocacy,” said Kim. This partnership comes following the recent five-year anniversary of the U.S. Food and Drug Administration (FDA) approval of Qelbree for ADHD. As of May 2026, Qelbree is the #1 prescribed branded non-stimulant ADHD medication and has been widely used in real-world clinical practice since approval.

“Our focus remains on listening to and learning from real patient stories to help address personalized needs, since no two people experience ADHD in the exact same way,” said Jack Khattar, President and Chief Executive Officer of Supernus Pharmaceuticals. “We’re thrilled to join forces with Chloe Kim to spark honest conversations and share new perspectives that may help others feel understood and see themselves in her story.”
