Some drugs can increase Wakix levels. Your healthcare provider may reduce your dose of Wakix if you take:

Paxil (paroxetine) Prozac (fluoxetine) Quinidine  Wellbutrin (bupropion)

Certain medicines increase your risk of developing heart rhythm problems from Wakix. Let your healthcare provider know if you take:

This is not a complete list of all the drugs that may interact with Wakix. Always keep an up-to-date list of all the medicines you take, and let your healthcare provider and pharmacist know any time there are changes. 

What Medications Are Similar?

Wakix belongs to a group of medications called histamine-3 inverse agonists. It is the only medication used to treat narcolepsy in this group. 

Most narcolepsy medicines treat either excessive daytime sleepiness or cataplexy. Because many patients with narcolepsy experience both of these symptoms, they often need to take multiple medications. Wakix is unique because it treats both daytime sleepiness and cataplexy, so you may only need to take one drug. 

How Can I Stay Healthy While Taking Wakix?

If you’re living with the symptoms of narcolepsy, just getting through the day can be a challenge. An afternoon nap can help some people improve their daytime sleepiness, but it’s not enough for most people. Fortunately, effective medications, including Wakix, are available to help relieve these symptoms. 

Because Wakix may interact with many different drugs, it’s important to let your healthcare provider know about all your medicines, even over-the-counter, nonprescription products. Your provider may need to adjust your dose of Wakix to ensure you receive safe and effective treatment.
