Competitive Edge
Non-Stimulant Status

Challenges and Risks
Competition and Generic Threats
The ADHD market is crowded with both branded and generic options. Qelbree faces competition from established brands like Strattera and Intuniv, as well as generic versions of these drugs. However, Qelbree's unique features help it stand out[2].
Seasonal Variations
Qelbree's sales may follow seasonal patterns, with the back-to-school season being a critical period. The soft back-to-school season in 2023 highlighted the potential for seasonal variability in sales growth[2].
Slowing Prescription Growth
Recent data indicates a slowdown in Qelbree's prescription growth, with quarter-to-date growth reaching about 1% in Q3 2024, down from 4% in Q2 2024. This slowdown has raised concerns about the sustainability of aggressive growth projections[2].
Clinical Efficacy and Safety

The dose-response curve was bell-shaped, indicating that doses between 200 mg/d and 400 mg/d were most effective. The study also noted that the maximum efficacy occurred approximately 4 weeks after starting the medication[4].
Adverse Effects
The meta-analysis reported that viloxazine was associated with a higher risk of discontinuation due to adverse effects, such as poor appetite, headache, somnolence, and nausea. However, the overall discontinuation rate due to adverse effects was relatively low at 4.15%[4].
