Iatrogenic refractory epilepsy
Understanding apparent treatment resistance and why the diagnosis, medicine choice and treatment effects deserve review.
Review the reason before escalating treatment
Here, this phrase describes a possible treatment-related contribution to apparent resistance. It is a discussion framework, not a diagnosis to apply to yourself or a claim that all difficult epilepsy is caused by treatment.
Confirmed drug-resistant epilepsy remains an important condition requiring timely specialist assessment. Do not change or stop medicines on the basis of this page.

Iatrogenic refractory epilepsyWhen apparent treatment resistance calls for a careful diagnosis and treatment review.
Clinical and practical questions
How should this phrase be used precisely?
Use it as a descriptive discussion of treatment-related apparent resistance. Separate diagnostic error, seizure aggravation, treatment inadequacy and adverse effects from confirmed drug-resistant epilepsy. State the specific suspected mechanism rather than assigning a catch-all label.
ILAE · drug-resistant epilepsy definition ↗ · Smith et al. · epilepsy misdiagnosis in a specialist referral cohort ↗ · Genton et al. · seizure aggravation in selected juvenile myoclonic epilepsy patients ↗
What should be re-evaluated before further escalation?
Reconstruct the habitual events, classification, aetiology, actual exposure, treatment adequacy, interactions and tolerability. Consider event capture and specialist reassessment when the account or treatment response is discordant.
What must this discussion not imply?
It must not imply that all levetiracetam use is reflex prescribing, that all continuing seizures are iatrogenic, or that selected misdiagnosis and seizure-aggravation studies provide population-wide rates. Preserve timely referral for confirmed drug resistance.
