This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Ontario is used as an explicit Canadian implementation example, not as a national rule. Verify the equivalent pathway, formulary and escalation route in the patient’s province or territory.

Ontario source: bounded use

Provincial Guidelines for the Management of Epilepsy in Adults and Children supplies a Canadian implementation example for this summary. It must not be presented as the rule outside Ontario.

Source-attributed clinical priorities

  • After a first suspected seizure, assess reversible provocation, obtain witness detail and arrange timely neurologic investigation.
  • Choose antiseizure treatment by seizure type, epilepsy syndrome, comorbidity, interactions and reproductive considerations.
  • Provide individualized safety, driving and sudden-death counselling using the rules of the patient’s licensing jurisdiction.
  • Classify focal versus generalized onset before choosing long-term therapy because some agents can aggravate particular seizure types.

Practical assessment and management workflow

1
Obtain a witness description or video, recovery course, provoking factors, medication exposure and prior neurologic history.
2
Check glucose, pregnancy where relevant, ECG and targeted laboratory or imaging tests for the first-event context.
3
Arrange EEG and MRI through neurology when indicated without using a normal EEG to exclude epilepsy.
4
Review seizure freedom, adherence, adverse effects, mood, bone health, contraception and driving at follow-up.

Safety, red flags and urgent escalation

  • A seizure lasting five minutes, repeated seizures without recovery or persistent hypoglycemia needs emergency treatment.
  • Counsel about bathing, heights, machinery, sleep deprivation and individualized sudden-death risk.
  • Avoid abrupt antiseizure-drug withdrawal and account for enzyme-inducing interactions with contraception and anticoagulation.
