1. What is Wakix and what is it used for

Wakix contains the active substance pitolisant. It is a medicine used to treat adult, adolescent, and child patients over 6 years of age with narcolepsy, with or without cataplexy.

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

The active substance, pitolisant, binds to receptors in brain cells involved in stimulating the state of alertness. This helps to combat daytime sleepiness and cataplexy, and to promote the state of wakefulness.

2. What you need to know before you take Wakix

Do not take Wakix:

• If you are allergic to pitolisant or any of the other ingredients of this medicine (listed in section 6).
• If you have severe liver problems, as pitolisant is usually broken down in the liver and may increase to excessive levels in patients with severely impaired liver function.
• If you are breastfeeding.

Warnings and precautions

Talk to your doctor before taking Wakix if you are in any of the following situations:

• You have had anxiety or depression with suicidal thoughts in the past.
• You have liver or kidney problems, as the dose may need to be adjusted.
• You have a stomach ulcer or take any medicine that may irritate the stomach (such as anti-inflammatory drugs), as gastrointestinal reactions have been reported with Wakix.
• You have obesity or anorexia, as your body weight may have changed (increased or decreased) while taking Wakix.
• You have heart problems. Your doctor should regularly check these aspects during treatment with Wakix.
• If you have severe epilepsy.

If you are in any of these situations, talk to your doctor or pharmacist before taking Wakix.

Other aspects you should discuss with your doctor or pharmacist:

Some people with a history of psychiatric disorders have reported suicidal thoughts while taking this medicine. Tell your doctor immediately if you feel depressed or have suicidal thoughts (see section 4). Ask a family member or close friend to help you detect signs of depression or other changes in your behavior.

Children

Wakix should not be given to children under 6 years of age.

Using Wakix with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Wakix may affect how other medicines work, and other medicines may affect how Wakix works. Your doctor may need to adjust the dose.

In particular, be cautious if you take Wakix with certain antidepressants (such as imipramine, clomipramine, and mirtazapine) and certain medicines for treating allergic diseases (antihistamines such as maleate of feniramine, chlorpheniramine, diphenhydramine, promethazine, mepyramine, and doxylamine).

Talk to your doctor or pharmacist if you are taking any of the following medicines: rifampicin (antibiotic), phenytoin, carbamazepine, and phenobarbital (mainly used to control convulsions), quinidine, digoxin (used to treat arrhythmia), paroxetine, fluoxetine, venlafaxine, duloxetine (antidepressants), St. John's Wort (Hypericum perforatum) a herbal medicine for depression, bupropion (antidepressant or aid to stop smoking), cinacalcet (used to treat parathyroid gland disorders), terbinafine (used to treat fungal infections), metformin, repaglinide (used to treat diabetes), docetaxel, irinotecan (used to treat cancer), cisapride (used to treat esophageal reflux), pimozide (used to treat certain mental disorders), halofantrine (used to treat malaria), efavirenz (antiviral for treating HIV), morphine, paracetamol (used as pain relief), dabigatran (used to treat bleeding problems), and warfarin (used to treat heart conditions), probenecid (used to treat gout and gouty arthritis). Pitolisant can be used with modafinil and sodium oxybate.

Wakix may reduce the effectiveness of hormonal contraceptives, so you should use another safe contraceptive method (see section "Pregnancy").

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Wakix should not be used during pregnancy unless your doctor prescribes it. There is not enough information available to know if there are specific risks associated with the use of Wakix during pregnancy. Women must use contraceptive methods during treatment with Wakix and for at least 21 days after stopping treatment. Since Wakix may reduce the effectiveness of hormonal contraceptives, another safe contraceptive method should be used.

Breastfeeding

In animals, Wakix passes into breast milk. Patients taking Wakix should stop breastfeeding.

Driving and using machines

Be cautious when performing activities that require attention, such as driving cars and using machines. If you are not sure if your condition has a negative effect on your ability to drive, talk to your doctor.
