For Clinical Effectiveness, Adherence, and Withdrawal in Epilepsy Care, use the highest-yield facts to drive concrete treatment decisions. Pay particular attention to Greatest variability source: non-adherence (medication adherence <20% level variance), Carbamazepine: autoinduction at ~4 weeks; can worsen absence/myoclonic seizures, and Cenobamate: ~45% achieve ≥50% seizure reduction as add-on for refractory focal epilepsy when choosing therapy, counseling about risk, planning monitoring, and deciding when closer follow-up or escalation is needed.
