It is the lumryz medication sodium salt of gamma-hydroxybutyrate (GHB) and is classified as a Schedule III controlled substance under the Controlled Substances Act .
What this means: LUMRYZ is a once-nightly medication that helps manage two of the most disruptive symptoms of narcolepsy: sudden muscle weakness (cataplexy) and overwhelming daytime sleepiness. It is not a cure for narcolepsy but a treatment to help manage symptoms.
Who Is LUMRYZ For?
LUMRYZ is indicated for patients aged 7 years and older with narcolepsy who experience either:
-

-
Excessive Daytime Sleepiness (EDS): Persistent, overwhelming sleepiness during waking hours
Who It Is NOT Intended For:
-
Patients under 7 years of age (safety and efficacy not established)
-
Patients with succinic semialdehyde dehydrogenase deficiency
-
Patients taking sedative hypnotics or alcohol
-
Patients with hepatic impairment for initiation of therapy
Verification from the manufacturer or official documentation is recommended before determining suitability for any individual patient.
What Does LUMRYZ Do?
LUMRYZ works as a CNS depressant that helps consolidate nighttime sleep and reduce symptoms of narcolepsy. The precise mechanism by which sodium oxybate lumryz cost produces its effects is not fully understood, but it is thought to promote slow (delta) wave sleep and improve sleep architecture .
In clinical trials, LUMRYZ demonstrated:
| Outcome | Finding |
|---|---|
| Increased wakefulness during the day | Statistically significant improvement in sleep latency on the Maintenance of Wakefulness Test (MWT) versus placebo |
| Reduced cataplexy attacks | Dose-dependent reduction in weekly cataplexy episodes at 6g, 7.5g, and 9g doses |
| Improved daytime sleepiness | Significant reduction in Epworth Sleepiness Scale (ESS) scores |
| Improved nighttime sleep | Reduced transitions to wake or light sleep; increased deep (N3) sleep |
What This Means: Clinical data suggest LUMRYZ can meaningfully improve both daytime functioning and nighttime sleep quality for people with narcolepsy. However, individual responses vary, and results seen in clinical trials may not predict individual outcomes.
What Makes LUMRYZ Different From Other Sodium Oxybate Products?
LUMRYZ is the first and only once-nightly extended-release sodium oxybate formulation approved in the United States .
| Feature | LUMRYZ | Twice-Nightly Sodium Oxybate |
|---|---|---|
| Dosing frequency | Once per night, at bedtime | Twice per night (bedtime + 2.5–4 hours later) |
| Administration | Single dose before sleep | Two doses; requires waking for second dose |
| Formulation | Extended-release suspension | Immediate-release oral solution |
| Patient burden | No middle-of-night awakening required | Forced awakening for second dose |
| Dosing errors | Reduced risk of accidental early dosing | Increased risk of dosing errors |
What This Means: The once-nightly design may reduce the burden and sleep disruption associated with twice-nightly dosing. In an open-label study, most patients who switched from twice-nightly to once-nightly sodium oxybate preferred the once-nightly formulation .
