SUNOSI (solriamfetol) is a prescription medication designed to improve wakefulness in adults who experience excessive daytime sleepiness (EDS) associated with narcolepsy or obstructive sleep apnea (OSA). It belongs to a class of drugs known as dopamine and norepinephrine reuptake inhibitors (DNRI), which work by altering the levels of certain neurotransmitters in the brain to help promote wakefulness. SUNOSI is taken orally, typically once a day in the morning, with or without food. It is important for patients to follow their healthcare provider's instructions closely when taking SUNOSI, as it can have side effects and may not be suitable for everyone. As with any medication, the benefits and risks should be discussed with a healthcare professional.
