Xcopri uses: what cenobamate is prescribed for
Cenobamate treats focal (partial-onset) seizures in adults. In clinical trials, a notable share of people with hard-to-treat epilepsy became seizure-free at higher doses.[1]
It works in two ways: it reduces persistent sodium currents and enhances GABA-A receptors.
Xcopri dosage: how cenobamate is usually prescribed
The figures below come from the FDA-approved label and describe how prescribers typically use cenobamate. They are not personal dosing advice. A prescriber sets the dose for each person and adjusts it over time.[1]
| Product | Typical adult dose | Notes from the label |
|---|---|---|
| Weeks 1 and 2 | 12.5 mg once a day | Slow titration lowers DRESS risk |
| Weeks 3 to 10 | Increase every 2 weeks: 25, 50, 100, 150 mg | Follow the titration pack |
| Maintenance | 200 mg once a day | Maximum 400 mg a day |
| Mild to moderate liver impairment | Maximum 200 mg a day | Not for severe liver impairment |
Xcopri (cenobamate) side effects and risks
Common side effects include sleepiness, dizziness, tiredness, double vision, and headache.[1]
DRESS: a serious multi-organ allergic reaction occurred in early studies when doses were increased quickly; slow titration lowers the risk.[1]
QT shortening: it shortens the QT interval and must not be used in people with familial short QT syndrome.[1]
Mood: like all antiseizure medicines, it carries a warning about a small increase in suicidal thoughts and behavior. Report new or worsening depression, anxiety, or agitation.[1]
Xcopri interactions: what not to mix with cenobamate
Choose what it would be combined with:
| Combined with | What happens | Label guidance |
|---|---|---|
| Hormonal contraceptives | Reduced effectiveness | Use additional or non-hormonal methods |
| Phenytoin, phenobarbital, clobazam | Higher levels of these drugs | Lower their doses |
| Lamotrigine, carbamazepine | Lower levels of these drugs | Dose adjustments may be needed |
| Alcohol and sedatives | More drowsiness | Use caution |
This is not a full list. A pharmacist can check a complete medication list, including supplements and over-the-counter products.[1]
Xcopri overdose: signs of cenobamate overdose and what to do
Overdose is expected to cause drowsiness, dizziness, unsteadiness, and possibly heart rhythm changes.[1]
If someone may have overdosed
- Call 911 if the person is unresponsive, hard to wake, or breathing slowly.
- For advice when the person is awake and stable, call Poison Help at 1-800-222-1222 (US, free, 24 hours).
- If opioids could be involved, including pills not from a pharmacy, give naloxone if you have it. Naloxone does not reverse cenobamate, but it will not harm the person.
- Stay with the person and place them on their side if they are drowsy or vomiting.
What happens if you stop cenobamate suddenly?
Cenobamate has low misuse potential, which is why it is in Schedule V. The main danger of stopping suddenly is not withdrawal but a rise in seizures.[1]
- DaysSeizure riskSeizures can return or become more frequent, including prolonged seizures.
- TaperGradual reductionThe label advises tapering over at least a week or longer.
- OngoingReassessChanges in seizure medicines should be planned with a neurologist.
Warning: Do not stop cenobamate suddenly without talking to the prescriber. Stopping antiseizure medicines abruptly can trigger prolonged, dangerous seizures.
How to get prescribed Xcopri (cenobamate) legally in the US
In the United States, cenobamate is a Schedule V controlled substance. The only legal way to get it is with a prescription from a clinician registered with the Drug Enforcement Administration (DEA), filled by a licensed pharmacy. Depending on state law, that can be a physician, nurse practitioner, or physician assistant.[2]
- Refills: Schedule V prescriptions can be refilled as the prescriber authorizes, subject to state law.[2]
- Telehealth: federal flexibilities let DEA-registered clinicians prescribe Schedule II to V medicines after a telemedicine visit, without a prior in-person exam, through December 31, 2026. A permanent DEA rule was under final review in late 2026. State rules can be stricter.[3]
- Monitoring: prescribers and pharmacists in most states check a prescription drug monitoring program, a database of controlled-substance prescriptions, before prescribing or dispensing.
- Pharmacies: a legitimate pharmacy always requires a valid prescription, has a licensed pharmacist available, and is licensed in the state it ships to. The FDA's BeSafeRx tool and the NABP's safe pharmacy list help confirm a pharmacy is real.[4][5]
- Cost: xcopri is brand-only and expensive without insurance; the maker offers savings programs.
Traveling: keep the medicine in its original pharmacy container and carry a copy of the prescription. Check the rules of the destination country before travel, because many countries restrict controlled medicines or require a permit.
Can you order Xcopri (cenobamate) online legally?
Yes, but only with a valid prescription and only from a pharmacy licensed in your state. Many licensed pharmacies, including mail-order pharmacies run by insurers, fill cenobamate prescriptions online and ship them. Buying cenobamate from a website that does not require a prescription is illegal, and the product is often fake.[4][6]
- See a licensed clinicianA clinician evaluates you in person or by telemedicine and decides whether cenobamate is appropriate.
- The prescription goes to a pharmacyPrescriptions are usually sent electronically, straight from the prescriber to the pharmacy you choose.
- The pharmacy checks and fills itA pharmacist verifies the prescription and your identity, then dispenses the medicine in person or by mail.
Signs that an online seller is illegal:
- It sells cenobamate with no prescription, or after only a short online questionnaire.
- It takes orders through social media, messaging apps, or email.
- It asks for payment in cryptocurrency, gift cards, or money transfers.
- It has no US street address, no state pharmacy license, and no pharmacist to speak to.
- Its prices are far below those of ordinary pharmacies, or it ships from another country.
The FDA's BeSafeRx tool links to each state's license lookup, and the National Association of Boards of Pharmacy lists verified online pharmacies.[4][5]
Xcopri price: how much does Xcopri (cenobamate) cost without insurance?
Xcopri is brand-only and expensive without insurance; the maker offers savings programs.
What you pay depends on the strength, the number of doses, your insurance plan, and the pharmacy. Cash prices for the same prescription can differ several times over between pharmacies in the same town, so check current prices before you fill it.
Ways to pay less, legally:
- Ask the prescriber whether a generic cenobamate is available. FDA-approved generics work the same way as the brand and usually cost much less.
- Compare cash prices between pharmacies before you fill the prescription.
- Use a free prescription discount card, such as GoodRx or SingleCare, when you pay cash. These cards cannot be combined with insurance on the same fill.
- For brand-name medicines, check the manufacturer's savings program or patient assistance program.
- Ask about a 90-day supply or your insurer's mail-order pharmacy, which often lowers the cost per dose when your prescriber agrees it is appropriate.
Warning: A price far below what licensed pharmacies charge, especially with no prescription required, is a strong sign of an illegal seller and counterfeit medicine.[4]

Common questions about Xcopri (cenobamate)
Why does Xcopri have to be started slowly?
Fast increases were linked to DRESS, a serious allergic reaction, so doses are raised every 2 weeks.
Is Xcopri (cenobamate) effective?
In trials it substantially reduced seizures, and some people with hard-to-treat epilepsy became seizure-free.
Does Xcopri (cenobamate) affect birth control?
Yes. It can make hormonal contraceptives less effective.
Why is Xcopri a controlled substance?
It produced euphoria-like effects at high doses in studies, so it is in Schedule V.
How long does Xcopri (cenobamate) stay in your system?
Its half-life is 50 to 60 hours, so it takes over a week to clear.
Can you buy Xcopri (cenobamate) without a prescription?
No. Xcopri (cenobamate) is a Schedule V controlled substance in the US, so it is illegal to buy or possess it without a valid prescription. Websites and social media sellers that offer it without one are not legal pharmacies, and the FDA warns that products sold this way are often counterfeit, contaminated, or the wrong strength. The legal route is a visit with a licensed clinician, in person or by telehealth, and a prescription filled at a state-licensed pharmacy. The FDA's BeSafeRx tool and the NABP's safe pharmacy list help confirm an online pharmacy is real.
