Xcopri is the brand name for perampanel, an antiseizure medication (AED).
Key points:
- How it works: Perampanel is a noncompetitive antagonist of AMPA receptors, which helps reduce excessive electrical activity that can lead to seizures.
- Use: It’s used as an add-on (adjunctive) therapy for seizures associated with partial-onset seizures. Dosing and eligibility depend on age and individual medical history, so your clinician will tailor this.
- Dosing: Usually taken once daily at bedtime, with gradual titration by your doctor. Typical maintenance ranges are in the low to mid single digits mg per day, with a maximum of around 12 mg daily. Exact dosing depends on age, weight (in kids), other meds, and response.
- Safety notes:
- Common side effects: dizziness, sleepiness, fatigue, gait disturbance, irritability.
- Neuropsychiatric effects: mood changes, aggression or hostility, irritability, and in some cases psychosis. There is a warning about suicidality; monitor for mood changes and seek help if you notice new or worsening thoughts or behavior.
- Interactions: perampanel is metabolized by CYP3A4. Drugs that strongly induce or inhibit CYP3A4 can lower or raise perampanel levels (e.g., carbamazepine, phenytoin, oxcarbazepine can reduce levels; certain antifungals like ketoconazole can raise levels). Alcohol can increase sedation.
- Pregnancy and contraception: discuss with a clinician—risks exist to a fetus, and effective contraception is often advised while on this medication.
- Do not stop abruptly: abrupt discontinuation can worsen seizures; tapering is usually recommended.
If you want, tell me:
- Your age (or the age of the person taking it)
- Other medications you’re taking
- What you want to know most (how it might affect you, side effects, cost/insurance, etc.)
I can tailor the information or look up the exact dosing for a specific age group. This is general info and not a substitute for medical advice. If you’re considering starting Xcopri or have safety concerns, discuss with your prescribing clinician.
