Sample item

Why should some antiepileptic drugs not be stopped abruptly?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Risk of seizure recurrence

Abrupt withdrawal may lower seizure threshold and trigger recurrence or status epilepticus, so medication changes should usually be gradual and supervised.

Option by option

  • A. Reduced drug interaction

    Withdrawal may increase rather than reduce clinical risk.

  • B. Permanent cure

    Stopping treatment does not prove permanent cure.

  • C. Risk of seizure recurrence (correct)

    Correct: sudden withdrawal can precipitate seizures.

  • D. Improved sleep immediately

    Sleep improvement is not a reason to abruptly discontinue therapy.
