The information below describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. They’ll determine the best dosage to fit your needs.
Dosage for focal onset seizure
When you first start taking Xcopri, your doctor will recommend a dose titration. This means that your doctor will gradually increase your dose until you reach a maintenance dosage that’s right for you. This slow increase of your dose over time gives your body time to adjust to the medication and decreases the risk of side effects.
For the first 2 weeks of treatment, you’ll likely take 12.5 mg of Xcopri once per day. After that, your dose will be increased every 2 weeks until your seizures are well managed. Your doctor will also monitor you for side effects as your dose is increased.
- Weeks 1 and 2. One dose of 12.5 mg per day.
- Weeks 3 and 4. One dose of 25 mg per day.
- Weeks 5 and 6. One dose of 50 mg per day.
- Weeks 7 and 8. One dose of 100 mg per day.
- Weeks 9 and 10. One dose of 150 mg per day.
- Weeks 11 and 12. One dose of 200 mg per day.
The recommended maintenance dosage is 200 mg taken once daily. But depending on how your body responds to the medication, your doctor may choose to continue increasing your dose every 2 weeks by 50 mg. For example, your doctor might recommend that you take a dose of 250 mg per day for weeks 13 and 14 and a dose of 300 mg per day for weeks 15 and 16.
The maximum recommended dosage of Xcopri is 400 mg per day.
Is Xcopri used long term?
Yes, Xcopri is usually used as a long-term treatment. If you and your doctor determine that it’s safe and effective for your condition, you’ll likely take it long term.
If you have liver disease, the maximum recommended dosage of Xcopri is typically lowered to 200 mg once per day. The drug is generally not recommended for people who have severe liver disease or liver failure.
If you have kidney disease, your doctor may consider lowering your dosage. But if you have end stage kidney disease and are on dialysis, your doctor will likely recommend a different treatment for you.
The dosage of Xcopri you’re prescribed may depend on several factors. These include:
- how your seizures respond to the medication
- whether you experience side effects
- other conditions you may have (see “Dosage adjustments” just above)

Accessible drug containers and labels
Some pharmacies provide medication labels that:
- have large print or use braille
- feature a code you can scan with a smartphone to change the text to audio
Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t.
If you have trouble opening medication bottles, let your pharmacist know. They may be able to supply Xcopri in an easy-open container. They may also have tips to help make it simpler to open the drug’s container.
If you miss a dose of Xcopri, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the dose. You should not take two doses of Xcopri at once to make up for a missed dose. If you miss a dose and you aren’t sure whether you should take the missed dose, talk with your doctor or pharmacist.
If you need help remembering to take your dose of Xcopri on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone.
Do not take more Xcopri than your doctor prescribes, as this can lead to serious side effects.
What to do in case you take too much Xcopri
Call your doctor right away if you think you’ve taken too much Xcopri. You can also call 800-222-1222 to reach America’s Poison Centers or use its online resource. But if you have severe symptoms, immediately call 911 (or your local emergency number) or go to the nearest emergency room.
Xcopri may cause dependence. With dependence, your body needs the drug to function as usual. If you suddenly stop taking Xcopri, you may experience withdrawal symptoms, such as:
For these reasons, if you and your doctor decide that you should stop taking Xcopri, it’s safer to do so using a drug taper.
With a drug taper, your dosage is gradually decreased over a couple of weeks. If you develop any withdrawal symptoms, your dosage may be briefly increased again, and then the taper started again at a slower pace. This will all be done under the supervision of your doctor.
The sections above describe the usual dosages provided by the drug’s manufacturer. If your doctor recommends Xcopri for you, they’ll prescribe the dosage that’s right for you.
Remember, you should not change your dosage of Xcopri without your doctor’s recommendation. Only take Xcopri exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage.
