What is Wakix?

Wakix tablets are used to treat adults with excessive daytime sleepiness (EDS) or cataplexy (sudden loss of muscle strength) both are symptoms of narcolepsy, which is a long-term sleep disorder.

Wakix is thought to work by changing the amount of histamine in the area of the brain that controls sleep and wakefulness, as it acts on the histamine-3 (H3) receptor.

Narcolepsy is a disorder that affects how well the brain control sleep-wake cycles. Often people with narcolepsy have interrupted sleep and may feel very sleepy during the day, which interferes with their life. Everyone that has narcolepsy has excessive daytime sleepiness, which is when they have an overwhelming sense of sleepiness that comes on quickly.

Cataplexy is when you have a sudden loss of muscle tone while you are awake, which leads to muscle weakness and loss of muscle control. Cataplexy can be mild and only last a short time, or it can be severe with a full body collapse.

Wakix is the only FDA-approved medicine for narcolepsy medicine that is not a controlled substance treatment.

Wakix is not a stimulant medicine.
