Wakix and Interactions: Other Drugs, Supplements, and More

Before you start taking Wakix, tell your doctor and pharmacist about any prescription, over-the-counter, or other drugs you take. Sharing this information with them may help prevent possible interactions. (To learn whether Wakix interacts with herbs or vitamins and supplements, see the “Are there other interactions with Wakix?” section later.)
If you have questions about drug interactions that may affect you, talk with your doctor or pharmacist.

When should I avoid Wakix?
Certain health conditions or other factors could raise your risk of harm if you take Wakix. In such cases, your doctor may not prescribe Wakix for you. These are known as contraindications. The list below includes contraindications of Wakix.
If you have a severe liver condition: It’s not known whether Wakix is safe for people with a severe liver condition. The drug hasn’t been studied in this population. Your liver is responsible for breaking down Wakix, and having a liver condition can cause your body to break down the drug more slowly than usual. This could cause levels of the drug to build up in your body, which raises your risk of side effects.
If you have a liver condition, talk with your doctor about whether Wakix is right for you.
If you’ve had an allergic reaction: If you’ve had an allergic reaction to Wakix or any of its ingredients, your doctor likely won’t prescribe Wakix for you. This is because using the drug could cause another allergic reaction. You can ask your doctor about other treatments that may be better options for you.
Before you start using Wakix, talk with your doctor if any of the factors above apply to you. Your doctor can determine whether Wakix is safe for you to take.
Does Wakix interact with alcohol?
Wakix is not known to interact with alcohol. But alcohol can affect sleep quality and could worsen narcolepsy symptoms in some people.
If you have questions about consuming alcohol with your condition or treatment plan, talk with your doctor or pharmacist.
Drug interactions explained
Learn more about certain drug interactions that can occur with Wakix.
Interaction with certain antidepressants
Wakix can interact with certain antidepressants, which are used to treat depression and other mental health conditions.
Examples of antidepressants that can interact with Wakix include:
What could happen
Taking Wakix with an antidepressant it interacts with can slow or block the activity of the enzyme (a type of protein) that breaks down Wakix in your body. This can increase the level of Wakix in your body, which can raise your risk of side effects from the drug.
What you can do
If you take Wakix with an antidepressant it interacts with, your doctor may prescribe a lower Wakix dosage for you.
If you have questions about taking Wakix with any of these antidepressants, talk with your doctor or pharmacist.
Interaction with certain antiseizure drugs
Wakix can interact with the antiseizure drugs carbamazepine (Tegretol, others) and phenytoin (Dilantin). These medications are used to treat seizures, among other uses.
What could happen
Taking phenytoin or carbamazepine with Wakix can make Wakix less effective. Phenytoin and carbamazepine can increase the activity of a certain enzyme that helps break down Wakix in your body. This can result in lower Wakix levels in your system, which may make the drug less effective.
What you can do
If you take Wakix with phenytoin or carbamazepine, your doctor may prescribe a higher Wakix dosage for you. You should not take a higher dose of either medication than your doctor prescribes.
Interaction with certain antihistamines
Wakix can interact with antihistamines. Antihistamines have many uses, such as treating allergies or allergic reactions and treating nausea and vomiting.
Examples of antihistamines that interact with Wakix include:
What could happen
Antihistamines work by blocking histamine, and Wakix works by increasing histamine in the brain. So taking certain antihistamines with Wakix may prevent Wakix from working.
What you can do
Your doctor will likely recommend that you avoid using an antihistamine that interacts with Wakix. Instead, they can discuss alternatives to either Wakix or the antihistamine.
Are there other interactions with Wakix?
Wakix may have other interactions. They could occur with supplements, foods, vaccines, or even lab tests. See below for details. Note that the information below does not include all other possible interactions with Wakix.
Does Wakix interact with supplements?
Before you start taking Wakix, talk with your doctor and pharmacist about any herbs or vitamins and supplements you take. Sharing this information with them may help you avoid possible interactions.
If you have questions about interactions that may affect you, talk with your doctor or pharmacist.
Wakix interactions with herbs
Wakix can interact with St. John’s wort, which is used to ease symptoms of depression and other conditions. Combining St. John’s wort with Wakix could make Wakix less effective. Your doctor may suggest you avoid taking St. John’s wort if you’re prescribed Wakix.
For this reason, it’s important to check with your doctor or pharmacist before taking St. John’s wort or other herbal products while taking Wakix.
Wakix interactions with vitamins
There are currently no reports of Wakix interacting with vitamins. But this doesn’t mean that vitamin interactions won’t be recognized in the future.
For this reason, it’s still important to check with your doctor or pharmacist before taking any of these products while using Wakix.
Does Wakix interact with food?
There are currently no reports of Wakix interacting with food. If you have questions about eating certain foods during your treatment with Wakix, talk with your doctor.
Does Wakix interact with vaccines or lab tests?
There are currently no reports of Wakix interacting with vaccines or lab tests. If you have questions about receiving certain vaccines or having lab tests done during your Wakix treatment, talk with your doctor.
Does Wakix interact with cannabis or CBD?
There are currently no reports of Wakix interacting with cannabis (commonly called marijuana) or cannabis products such as cannabidiol (CBD). But as with any drug or supplement, talk with your doctor before using cannabis with Wakix.
However, your doctor may suggest avoiding cannabis if you have narcolepsy. Cannabis could worsen excessive daytime sleepiness, which Wakix is prescribed to treat.
Note: Cannabis is illegal at a federal level but is legal in many states to varying degrees.
Does my health history affect whether I should take Wakix?
Certain medical conditions or other health factors may raise the risk of interactions with Wakix. Before using Wakix, talk with your doctor about your health history. They’ll determine whether Wakix is right for you.
Health conditions or other factors that might interact with Wakix include:
Long QT syndrome: Wakix lengthens the QT interval (a part of your heart’s rhythm). If you have long QT syndrome, the drug can worsen your condition. Due to this risk, your doctor will likely avoid prescribing Wakix if you have long QT syndrome.
Severe liver condition: It’s not known whether Wakix is safe for people with a severe liver condition. The drug hasn’t been studied in this population. Your liver is responsible for breaking down Wakix, and having a liver condition can cause your body to break down the drug more slowly than usual. This could cause levels of the drug to build up in your body, which raises your risk of side effects.
Pregnancy: It’s not known whether Wakix is safe to take during pregnancy. If you’re pregnant or planning a pregnancy, talk with your doctor before using Wakix.
If you do take Wakix while pregnant, consider enrolling in the drug’s pregnancy registry. This registry collects details about pregnancy issues reported with Wakix. To learn more, call 1-800-833-7460 or visit the registry website. You can also talk with your doctor for more details.
Breastfeeding: It’s not known whether it’s safe to use Wakix while breastfeeding. The drug passes into breast milk, but it isn’t known whether the drug may cause side effects in a child who’s breastfed. If you’re breastfeeding or planning to do so, talk with your doctor about your options.
Allergic reaction: If you’ve had an allergic reaction to Wakix or any of its ingredients, your doctor will likely not prescribe Wakix. This is because taking the drug could cause another allergic reaction. You can ask your doctor about other treatments that may be better choices for you.
