Patient Education

Calcium, Magnesium, Potassium, and Sodium Oxybate


Calcium, magnesium, potassium, and sodium oxybate is used to treat attacks of cataplexy (episodes of muscle weakness that begin suddenly and last for a short time) and excessive daytime sleepiness in adults and children 7 years of age and older who have narcolepsy (a sleep disorder that may cause extreme sleepiness, sudden uncontrollable urge to sleep during daily activities, and cataplexy). Calcium, magnesium, potassium, and sodium oxybate is in a class of medications called central nervous system depressants. Calcium, magnesium, potassium, and sodium oxybate works to treat narcolepsy and cataplexy by reducing activity in the brain.
