Internal Medicine

Solriamfetol (brand name Sunosi) is a wakefulness-promoting medication prescribed to treat excessive daytime sleepiness (EDS) in adults with narcolepsy. It is typically considered when first-line therapies have not provided adequate symptom control. By supporting daytime alertness, solriamfetol can help improve daily functioning, safety, and quality of life for people living with narcolepsy.

Because excessive daytime sleepiness can stem from many conditions—not just narcolepsy—identifying the root cause is essential before pursuing treatments like solriamfetol. Sleep apnea, thyroid issues, depression, and other disorders can produce similar symptoms, and each requires a different approach. Taking a free, instant, online symptom check can help you clarify what may be driving your fatigue, understand possible conditions, and prepare for a more productive conversation with your doctor about next steps.
