New Data Highlights the Dosing Flexibility of Low-Sodium Oxybate
Jazz Pharmaceuticals presented data at SLEEP 2026 showing Xywav's dosing flexibility for narcolepsy and idiopathic hypersomnia, with stable regimens achievable in ~42 days. Real-world data indicates 91% use twice-nightly regimens, but clinicians often customize doses. Studies also show cardiovascular benefits of low-sodium oxybate. According to Jazz, Xywav's individualized dosing can improve patient outcomes.
