- Levonorgestrel (reduced efficacy when co-administered with perampanel at doses >8 mg/day)
Monitoring
Baseline Monitoring
Rationale: To identify pre-existing psychiatric conditions or risk factors for behavioral changes, aggression, or suicidal ideation.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Regularly, at each follow-up visit.
Target: Reduction in seizure frequency, improved seizure control.
Action Threshold: Lack of efficacy may warrant dose increase or alternative therapy; worsening seizures require re-evaluation.
Frequency: Regularly, at each follow-up visit, and instruct patients/caregivers to report immediately.
Target: Absence of new or worsening psychiatric symptoms.
Action Threshold: Emergence or worsening of symptoms requires dose reduction, discontinuation, or psychiatric consultation.
Frequency: Regularly, especially during titration.
Target: Tolerable levels of side effects.
Action Threshold: Severe or persistent symptoms may require dose reduction or discontinuation.

Special Patient Groups
Pregnancy
Perampanel is classified as Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Patients should be enrolled in the North American Antiepileptic Drug (NAAED) Pregnancy Registry if they become pregnant while taking perampanel.
Trimester-Specific Risks:
Lactation
Perampanel is excreted into human milk. The decision to discontinue nursing or discontinue the drug should take into account the importance of the drug to the mother and the potential adverse effects on the infant. Monitor breastfed infants for somnolence, irritability, and poor feeding.
Pediatric Use
Approved for adjunctive treatment of focal onset seizures in patients 4 years of age and older, and for adjunctive treatment of primary generalized tonic-clonic seizures in patients 12 years of age and older. Dosing is weight-based for younger children. Safety and efficacy in patients younger than 4 years have not been established.
Geriatric Use
No specific dose adjustment is required based on age. However, elderly patients may be more sensitive to the adverse effects (e.g., dizziness, somnolence, gait disturbance) and should be monitored closely.
Clinical Information
Clinical Pearls
- Perampanel has a long half-life, allowing for once-daily dosing and making it less prone to missed doses causing immediate withdrawal seizures.
- The Black Box Warning for psychiatric and behavioral reactions is significant; thoroughly counsel patients and caregivers and monitor closely, especially during titration.
- Dose adjustments are crucial when co-administering with enzyme-inducing AEDs (e.g., carbamazepine, phenytoin, oxcarbazepine) as they significantly reduce perampanel levels.
- Titrate slowly to minimize CNS side effects like dizziness and somnolence.
- The oral suspension formulation is useful for patients who have difficulty swallowing tablets or require precise dose adjustments.
- Advise patients about potential weight gain, which is a common side effect with long-term use of AEDs, including perampanel.
