1. what wakix is and what it is used for

Wakix contains the active ingredient pitolisant. It is a medicine used to treat adult patients with narcolepsy, with or without cataplexy.

Narcolepsy is a condition that causes excessive daytime sleepiness and a tendency to suddenly fall asleep in inappropriate situations (sleep attacks). Cataplexy is the onset of sudden muscle weakness or paralysis without losing consciousness, in response to a sudden emotional reaction such as anger, fear, joy, laughter or surprise.

The active substance, pitolisant, attaches to receptors on cells in the brain that are involved in stimulating alertness. This helps to combat daytime sleepiness and cataplexy and promote wakefulness.

2. what you need to know before you take wakix

Do not take Wakix if you

• – Are allergic to pitolisant or any °f the other ingredients of this medicine (listed in section 6).

• – Have severe liver problems, as pitolisant is normally broken down in the liver and excess levels may build up in patients whose liver function is severely reduced.

• – Are breastfeeding.
