Epilepsy is a neurological disorder characterized by recurrent seizures, which are sudden bursts of abnormal electrical activity in the brain. Seizures can be

generalised

or

focal

. Generalised seizures involve widespread brain activity, often leading to loss of consciousness and convulsions. Focal seizures, on the other hand, originate in a specific brain area, causing localized symptoms that may spread (secondary generalised seizures).

Perampanel works by blocking the action of glutamate, a neurotransmitter that excites nerve cells, thereby stabilising electrical activity in the brain and reducing seizure frequency. It is typically used as an adjunctive therapy alongside other anti-seizure medications (ASMs), but emerging evidence supports its use as monotherapy or early add-on treatment, particularly in focal-onset seizures (FOS).

The ELEVATE study, a US-based phase IV open-label trial, demonstrated perampanel’s effectiveness as monotherapy or first adjunctive therapy in pediatric and adult patients with epilepsy. In this study, 88.9% of patients experienced treatment-emergent adverse events (TEAEs), but serious events were low at 7.4%, supporting its role in early-line treatment.

FDA approvals confirm its indications: adjunctive therapy for partial-onset seizures (with or without secondary generalization) in patients 4 years and older, and primary generalized tonic-clonic seizures (PGTCS) in those 12 and older.

How to take perampanel

Before beginning perampanel, carefully read the manufacturer’s patient information leaflet, which details usage, side effects, and precautions. Always follow your doctor’s instructions precisely.

Perampanel is administered as a

once-daily dose at bedtime

to minimize daytime drowsiness. Treatment starts at a low dose, gradually increasing to allow the body to adjust and optimize efficacy while reducing side effects. Your doctor will provide a personalized schedule, reflected on the medication label.

• Starting dose: Typically 2 mg daily for adults; adjustments for children based on weight and age.
• Titration: Increase by 2 mg weekly up to a maintenance dose of 4-12 mg/day, depending on response and tolerability.
• Missed dose: Skip the forgotten dose and resume the next scheduled one. Never double up.
• Tablets: Swallow whole with water; do not chew, crush, or break.
• Oral suspension: Shake well and measure with provided syringe.

Do not abruptly stop perampanel without medical advice, as this can precipitate seizures or status epilepticus. Gradual tapering is essential.

Getting the most from your treatment

To maximize benefits and safety:

• Take exactly as prescribed; consistency is key for steady blood levels.
• Avoid alcohol, as it heightens dizziness and drowsiness risks.
• Monitor seizure frequency and report changes to your doctor.
• Regular blood tests may be needed to check levels and liver function.
• Inform your doctor of all medications to avoid interactions, especially with enzyme-inducing ASMs that may require dose adjustments.

Early response to ASMs like perampanel correlates with better long-term prognosis. Studies show better outcomes with fewer prior ASMs.

Side-effects

Common side effects are usually mild and diminish over time. The table below outlines frequent effects and management strategies:

Side Effect	What to Do
Feeling dizzy, sleepy, tired, unsteady; double vision	Avoid falls; do not drive or operate machinery
Feeling sick (nausea)	Eat simple foods; avoid fatty/spicy meals
Changes in appetite/weight, mood (aggression, confusion, anxiety), back pain	Speak to your doctor if persistent

Other reported effects include irritability, falls, vertigo, ataxia, headache, vomiting, and anxiety. Dizziness and somnolence are dose-related and most prominent early in treatment. In the ELEVATE study, TEAEs occurred in 88.9% of patients, but discontinuation due to AEs was low.

Serious risks: Psychiatric events (e.g., aggression, homicidal ideation), suicidal thoughts, and hypersensitivity reactions. Seek immediate help for severe mood changes or allergic symptoms.

How to cope with side-effects

Most side effects improve with time or dose adjustment:

• Dizziness/drowsiness: Rise slowly; bedtime dosing helps.
• Nausea: Take with food; ginger aids relief.
• Mood changes: Track symptoms; therapy or dose tweak may help.
• Weight gain: Maintain diet/exercise; monitor BMI.

Report unrelieved or worsening effects promptly.

Warnings

Perampanel carries risks including:

• Drowsiness: Impairs driving/machinery; assess tolerance first.
• Psychiatric: Monitor for aggression, hallucinations; higher risk at elevated doses.
• Falls: Common in elderly/children due to ataxia.
• Pregnancy: Registry recommended; potential fetal risks.
• Interactions: Carbamazepine reduces levels; levonorgestrel efficacy may decrease.

Important information about all medicines

Never share prescriptions. Inform doctors/dentists/pharmacists of perampanel use. Take at regular times. Store securely away from children.

Notes

Perampanel expands treatment options, especially for refractory epilepsy. Real-world data (PERMIT analysis) link early use to better seizure control and fewer AEs. Consult specialists for personalized advice.
