Febrile Seizure
Clinical Snapshot
A febrile seizure is a seizure occurring in association with a fever, in a child without evidence of intracranial infection, a defined metabolic disturbance, or a prior history of afebrile seizures — most commonly between about 6 months and 5 years of age (one commonly cited Canadian source frames the range slightly more broadly, from 3 months to 6 years).[1][2] Febrile seizures are common: they occur in roughly 2-5% of children in North America and Europe, and in up to about 14% of children of Asian ancestry.[1][3]
Febrile seizures are classified into two clinically important categories. A simple febrile seizure — generalized, lasting under 15 minutes, and occurring only once in a 24-hour period — accounts for roughly 80% of cases and is, on its own, a benign event.[1] A complex febrile seizure — with focal features, lasting 15 minutes or longer, or recurring within 24 hours — accounts for the remaining roughly 20% and warrants a more thorough evaluation.[1] A rare third category, febrile status epilepticus, is seizure activity (continuous or without full recovery between seizures) lasting 30 minutes or longer; it is uncommon but is associated with a less favourable outcome and needs urgent emergency management.[3]
The central reassurance point for this chapter: a simple febrile seizure, while alarming to witness, is generally benign. Children with normal development who have had one or more simple febrile seizures perform as well as their peers academically, intellectually, and behaviourally, and simple febrile seizures do not, on their own, warrant long-term antiepileptic drug therapy.[1] A pharmacist's role here runs from acute first-aid and rescue-medication counselling through to actively correcting two persistent parental misconceptions: that antipyretics prevent recurrence (they do not), and that a child who has had a febrile seizure needs daily seizure medication going forward (they generally do not).[1][4]
Recognize the Condition
What a typical episode looks like
A febrile seizure is typically a generalized tonic-clonic event: the body stiffens, the eyes may roll upward or deviate, and the limbs jerk rhythmically, often with a brief loss of consciousness; breathing can look irregular and the child may appear cyanotic around the lips during the convulsive phase.[2] Afterward, a period of drowsiness or confusion (the postictal state) is expected and typically resolves within minutes to roughly an hour, with the child gradually waking and returning to their usual self.[2]
Simple vs. complex — the key classification
| Feature | Simple febrile seizure (~80%) | Complex febrile seizure (~20%) |
|---|---|---|
| Onset | Generalized from the start | May have focal onset or focal features (e.g., movement confined to one side) |
| Duration | Under 15 minutes (most last well under 5) | 15 minutes or longer |
| Recurrence | Only once in 24 hours | More than once within 24 hours |
| Postictal exam | Todd's paresis absent; returns to baseline promptly | May include a transient focal (Todd's) paresis |
[1] This distinction matters clinically: a genuinely simple febrile seizure in a well-appearing, fully-recovered child needs little beyond identifying the fever source and reassurance, while complex features shift the plan toward more thorough evaluation (see Investigations) and, often, a paediatric neurology referral.
The essential red-flag differential: is this actually meningitis or encephalitis?
Every child presenting with a seizure and fever needs an active, deliberate assessment for signs of central nervous system infection before the event is accepted as a simple febrile seizure — this is the single most important differential in this chapter. Specifically examine for meningismus (nuchal rigidity, a bulging fontanelle in an infant, positive Brudzinski or Kernig signs) and confirm the child's mental status genuinely returns to baseline within the expected postictal window rather than remaining persistently altered.[1] A child who does not wake up and behave normally within a reasonable time after the seizure, who has any meningeal sign, or who looks unwell beyond what the seizure itself would explain needs urgent evaluation for bacterial meningitis or encephalitis rather than reassurance. This concern is sharper still in a child who is incompletely immunized or whose immunization status is unknown, since Haemophilus influenzae type b and Streptococcus pneumoniae — the classic causes of bacterial meningitis in this age group — are both vaccine-preventable.[5][1]
Other seizure etiologies and mimics worth knowing
- Breath-holding spells and rigors/shivering can be mistaken for a seizure by an anxious caregiver; a careful description of the event (was there true loss of consciousness, rhythmic jerking, and a postictal period?) usually distinguishes them.
- Genetic epilepsy with febrile seizures plus (GEFS+) should be considered when febrile seizures continue beyond the typical age range, are unusually frequent, or occur alongside afebrile seizures in a child with a strong family history of seizures/epilepsy.[3]
- Febrile infection-related epilepsy syndrome (FIRES) is a rare but serious presentation of new refractory status epilepticus following a febrile illness in a previously healthy child, and is an important reason a seizure that does not behave like a typical, self-limited febrile seizure needs prompt specialist evaluation rather than routine reassurance.[3]
Risk Factors
- Age is the dominant risk factor: incidence peaks between roughly 12 and 18 months, within the overall 6-month-to-5-year (or, per one Canadian source, 3-month-to-6-year) window in which febrile seizures are defined.[3][1]
- A positive family history is common and genuinely predisposing — roughly 10-33% of children with a febrile seizure have a first-degree relative with a history of febrile seizures.[3]
- Viral illness is the trigger in the large majority of cases; human herpesvirus-6 (causing roseola) is the most commonly identified virus in North America, while influenza A predominates in some other regions.[3]
- Recent vaccination (e.g., DTaP-containing combination vaccines, MMR/MMRV, and pneumococcal conjugate vaccine) is associated with a small, transient increase in febrile seizure risk in the days following the vaccine, on the order of roughly 30 additional febrile seizures per 100,000 children vaccinated — a genuinely useful number to have on hand, since it is reassuringly small and should not change vaccination recommendations.[3]
- Pre-existing neurological abnormality or developmental delay increases both the likelihood of a febrile seizure occurring and, notably, the likelihood of subsequent epilepsy if one does occur (see Special Populations).[1]
- Lower degree of fever at seizure onset and a shorter interval between fever onset and the seizure are both associated with a first febrile seizure occurring, and with recurrence (see Monitoring/Follow-up).[1]
Red Flags & Refer
Escalate beyond routine reassurance and first-aid counselling for any of the following:
- Seizure activity continuing 5 minutes or longer without stopping — this is the threshold at which rescue benzodiazepine treatment and emergency services become necessary; continuous seizure activity beyond about 30 minutes is febrile status epilepticus, a genuine emergency.[6][3]
- Any sign of meningismus (neck stiffness, bulging fontanelle, positive Brudzinski/Kernig) or altered mental status persisting beyond the expected postictal period — evaluate urgently for bacterial meningitis or encephalitis rather than accepting the event as a simple febrile seizure.[1]
- Incompletely immunized children, or those with unknown immunization status, presenting with a seizure and fever — the risk of an underlying bacterial CNS infection is higher, and a lumbar puncture is more strongly indicated (see Investigations).[5][1]
- Infant under 6 months with a seizure and fever falls outside the typical febrile-seizure age range and needs prompt medical assessment rather than reassurance at home.[2]
- Complex features — focal onset, duration of 15 minutes or longer, or more than one seizure within 24 hours — warrant more thorough evaluation and are not simply "a longer version" of a simple febrile seizure.[1]
- A first seizure with no clear source of fever identified, or a child who was recently started on or is currently taking antibiotics (which can partially mask evolving meningitis) — both lower the threshold for lumbar puncture and closer medical evaluation.[1][5]
Assessment & Diagnosis
Diagnosis is clinical
A simple febrile seizure is a clinical diagnosis based on a careful history of the event and examination of a child who has returned to baseline. Ask specifically about: a full description of the seizure itself (generalized vs. focal, duration, one episode or more than one), the fever's timeline relative to the seizure, immunization status, any recent or current antibiotic use, prior febrile or afebrile seizures, family history of seizures or epilepsy, and the child's baseline development.[1] On examination, identify the source of the fever, perform a full neurological exam once the child is alert, and specifically check for meningismus.
Differential diagnosis
| Condition | Key distinguishing features |
|---|---|
| Simple febrile seizure | Generalized, under 15 minutes, single episode in 24 hours, prompt return to baseline, no meningismus |
| Complex febrile seizure | Focal features, 15 minutes or longer, or more than one episode in 24 hours; may have a transient postictal (Todd's) paresis |
| Bacterial meningitis / encephalitis | Meningismus, bulging fontanelle, persistently altered mental status beyond the expected postictal window, may follow incomplete immunization or antibiotic pretreatment that masks early signs |
| Febrile status epilepticus | Continuous seizure activity, or seizures without full recovery in between, lasting 30 minutes or longer |
| Breath-holding spell / rigors | No true loss of consciousness with rhythmic convulsive movement, or a clear breath-holding/crying trigger; no true postictal period |
| GEFS+ / an evolving afebrile epilepsy | Febrile seizures continuing beyond the typical age range, unusually frequent, occurring alongside afebrile seizures, or a strong family history of epilepsy |
| FIRES | New refractory status epilepticus following a febrile illness in a previously healthy child — rare, but needs urgent specialist involvement |
Investigations
Lumbar puncture is not routine for a genuinely simple febrile seizure in a well-appearing child who has returned to baseline. Perform it when meningeal signs are present. Beyond that, Canadian guidance frames it as something to strongly consider in a child under 12 months of age or one who is currently on antibiotics (which can mask evolving meningitis), and to consider in a child under 18 months, reflecting how much less reliable meningeal signs are at younger ages.[1] American guidance frames a closely related criterion: lumbar puncture is an option specifically for infants 6-12 months of age whose Haemophilus influenzae type b or Streptococcus pneumoniae immunizations are incomplete or unknown, given the higher resulting risk of bacterial meningitis.[5] Reported rates of bacterial meningitis among children presenting with a febrile seizure range from roughly 1.8-5.4%, though this is lower in fully immunized populations.[1]
Blood glucose should be checked if the seizure lasts longer than 15 minutes or if the child's consciousness remains depressed longer than expected postictally.[1]
Routine EEG, bloodwork (electrolytes, calcium, CBC), and neuroimaging are not indicated for a simple febrile seizure and should not be performed reflexively — none of these change management or improve outcomes in a well-appearing child with a genuinely simple event.[1][5] A complex febrile seizure, by contrast, generally does warrant a more thorough evaluation, which may include EEG or neuroimaging as directed by the treating physician or a paediatric neurology referral, particularly with focal findings or an abnormal postictal exam.[3]
Treatment Targets
- Keep the child safe from injury during any seizure and correctly time its duration.
- Recognize promptly when a seizure has crossed the 5-minute threshold that calls for rescue medication (if prescribed) and emergency services, rather than continuing to simply observe.
- Actively screen every febrile seizure for the meningitis/encephalitis differential rather than assuming a benign event by default.
- Avoid unnecessary investigation (EEG, bloodwork, neuroimaging) in a genuinely simple febrile seizure, while applying the correct lumbar-puncture threshold when it is warranted.
- For children at higher risk of a prolonged recurrence, ensure a home rescue medication (if prescribed) is available, correctly stored, not expired, and that caregivers are confident and correctly trained in giving it.
- Correct the two persistent parental misconceptions that drive both anxiety and inappropriate treatment requests: that antipyretics prevent febrile seizure recurrence, and that a child needs daily antiepileptic medication after a simple febrile seizure.
- Deliver genuine, evidence-based reassurance about the excellent long-term prognosis of simple febrile seizures.
- Set clear, specific counselling around recurrence risk and what to do if it happens again.
Choose Initial Treatment
Acute management — timing drives the decision
Any seizure, first response position the child safely on their side, protect them from nearby hazards, loosen tight clothing around the neck, do not restrain the child or place anything in the mouth, and time the seizure from the moment it starts.[2] Stops within 5 minutes (the great majority of febrile seizures) no rescue medication is needed; once the seizure ends, keep the child on their side, allow gradual waking, and assess for the fever source once alert.[1][2] Continues 5 minutes or longer call emergency medical services immediately, and if a rescue benzodiazepine has been prescribed and the caregiver is trained, give it now while awaiting EMS — rectal diazepam or buccal/intranasal midazolam (see Rescue Medication Counselling below and Pharmacologic Treatment Options for dosing).[6][1] Do not treat a home rescue medication dose as a substitute for calling EMS — it is a bridge to emergency care, not a replacement for it, and a second dose or further airway/breathing support may still be needed.[6]
In-hospital management of an ongoing seizure
IV access available IV lorazepam is generally preferred; IV diazepam is an accepted alternative.[1][6] No IV access buccal or intranasal midazolam is the preferred first-line route — it works as fast as or faster than establishing IV access in an actively seizing child and does not require one.[6][1] No response within 5 minutes of the first dose a second dose of the same or an alternative benzodiazepine is appropriate; ongoing seizure activity despite two adequately dosed benzodiazepines needs escalation per local status-epilepticus protocol.[6]
Rescue medication counselling — who gets a prescription, and what to teach
A home rescue benzodiazepine is not routinely prescribed after every febrile seizure. It is a reasonable, guideline-supported prescription specifically for a child with a prior prolonged (5 minutes or longer) febrile seizure, or for a family living a significant distance from medical care, where a meaningful delay before EMS or emergency-department access could otherwise occur.[1] When one is prescribed, pharmacist counselling should explicitly cover: correct administration technique for the specific formulation (rectal gel applicator technique and positioning for diazepam; correct buccal placement between the lower gum and cheek, or correct intranasal technique with the dose split between nostrils if the volume is large, for midazolam), exactly when to give it (a seizure that has already reached 5 minutes, not "as soon as any seizure starts"), to call EMS at the same time, every time — never in place of it, expiry and storage (check the kit periodically; rectal diazepam gel and midazolam formulations do expire), and confirming every regular caregiver (both parents, grandparents, daycare staff) knows the plan, not just the prescribing visit's attendee.[1][6]
Long-term antiepileptic prophylaxis — routinely avoid it
Do not recommend or expect continuous daily antiepileptic therapy (e.g., phenobarbital, valproic acid) after a simple febrile seizure, even a recurrent one — current guidance is explicit that the risks (sedation, behavioural effects with phenobarbital; hepatotoxicity risk with valproic acid, particularly in young children) outweigh the modest recurrence-reduction benefit, and neither improves the long-term epilepsy risk.[4][1] Intermittent prophylaxis (e.g., diazepam given during febrile illnesses) is similarly not recommended for routine use and is reserved, if used at all, for exceptional, specialist-directed circumstances — for example, a child with very frequent, distressing recurrences under active neurology follow-up.[1][4]
Non-Pharmacologic Treatment
During the seizure — first aid
- Stay calm and stay with the child; remove nearby objects that could cause injury.
- Place the child on a flat surface, on their side, and do not attempt to move them further unless they are in immediate danger.[2]
- Do not restrain the child's movements and do not place anything — a spoon, a finger, or any object — in their mouth; this is an outdated and genuinely dangerous practice that risks airway obstruction or injury and does not prevent tongue-biting.[2]
- Gently clear vomit or saliva from around the mouth if present, without inserting anything inside it.[2]
- Time the seizure from the moment it starts — this single piece of information (was it under or over 5 minutes) is what actually drives the treatment decision.
- After the seizure stops, keep the child positioned on their side to allow secretions to drain, and allow gradual, unhurried waking — do not offer food, water, or medication until the child is fully alert and able to swallow safely.[2]
Fever management — for comfort, not seizure prevention
- Undress the child to light clothing and keep the room at a comfortable temperature; avoid over-bundling.
- Encourage adequate oral fluid intake once the child is alert.
- Use an antipyretic (acetaminophen or ibuprofen) at an appropriate weight-based dose for the child's comfort — but see Pharmacologic Treatment Options and Common Errors to Avoid for the critical counselling point that this does not reduce the chance of another febrile seizure.[1]
Reassurance and psychoeducation as core therapy
- Explain plainly, using the actual numbers where helpful, that a simple febrile seizure does not cause brain damage, does not reduce intellectual or academic performance in a normally developing child, and carries only a small increase in future epilepsy risk over the general population.[1]
- Provide a written seizure action plan for any family prescribed a home rescue medication, and confirm every regular caregiver has seen and understood it.
- Address the fear directly — many parents describe a first febrile seizure as one of the most frightening moments of their child's early life, and clear, specific, repeatable information is itself a genuine intervention.
Special Populations
Infants under 6 months
This age falls outside the typical febrile-seizure definition. A seizure with fever in an infant this young needs prompt, thorough medical evaluation for an underlying cause rather than being managed as a routine, reassurance-only simple febrile seizure.[2]
Children with pre-existing neurological abnormality or developmental delay
This group has a substantially higher risk of subsequent epilepsy after a febrile seizure than a developmentally normal child — reported at roughly 40% in children with conditions such as cerebral palsy or intellectual disability, compared with roughly 2.9% in children with normal development.[1] A lower threshold for specialist (paediatric neurology) involvement is appropriate in this group, and counselling on prognosis should be individualized rather than using the general reassurance framing given to a developmentally normal child.
Incompletely immunized children, or unknown immunization status
The risk of an underlying bacterial CNS infection presenting as an apparent febrile seizure is higher in this group, and lumbar puncture is more strongly indicated (see Investigations).[5][1]
Children with recurrent or complex febrile seizures
Multiple recurrences, any complex feature, an abnormal neurological exam or development, or a first afebrile seizure occurring later all warrant paediatric neurology referral rather than continued routine primary-care/pharmacist-level reassurance and management.
Families living a significant distance from medical care
This is one of the two specific groups for whom prescribing a home rescue benzodiazepine is genuinely appropriate, independent of whether a prior seizure was prolonged — the goal is to bridge the longer-than-usual interval before EMS or emergency-department access.[1]
Suspected GEFS+ or a family history of epilepsy
Febrile seizures continuing beyond the typical age range, unusual frequency, or a strong family history of epilepsy should prompt consideration of an underlying genetic epilepsy syndrome and a neurology referral rather than reflexively treating every recurrence as "just another febrile seizure."[3]
Monitoring & Follow-Up
- Arrange routine follow-up with the child's primary care provider or pediatrician after any emergency-department visit for a febrile seizure, even a simple one.
- For any family sent home with a prescribed rescue benzodiazepine, confirm at the pharmacy and at follow-up that the kit is on hand, has not expired, and that the caregiver can correctly describe both the administration technique and the "give it, then call EMS" sequence — do not assume a single counselling session is sufficient long-term.
- Counsel explicitly on recurrence risk: roughly 30-40% of children will have at least one recurrent febrile seizure, most often within the following 12 months.[1] Risk is higher with a first seizure under about 15-18 months of age, a positive family history, a shorter interval between fever onset and the seizure, and a lower temperature at the time of the seizure.[1]
- Reinforce the reassurance points at every follow-up contact, not only at the index visit — repetition genuinely helps anxious parents retain and believe this information.
- Watch for a change in pattern (increasing frequency, emerging focal features, or a first afebrile seizure) that should prompt reassessment and specialist referral rather than being folded into routine reassurance.
Common Errors to Avoid
- Restraining a child's movements or placing any object in the mouth during a seizure — an outdated practice that risks real harm and does not prevent tongue-biting.[2]
- Telling (or allowing) parents to believe that antipyretics prevent febrile seizure recurrence — they do not, though they remain entirely appropriate for comfort.[1]
- Recommending or expecting continuous daily antiepileptic therapy after a single, or even a recurrent, simple febrile seizure — current guidance is explicit that this is not indicated given an unfavourable risk-benefit balance.[4][1]
- Treating a home rescue medication dose as a substitute for calling EMS, rather than as a bridge to emergency care given alongside it.[6]
- Assuming every seizure occurring with a fever is automatically a simple febrile seizure without actively screening for meningismus and confirming a prompt return to baseline.[1]
- Ordering routine EEG, bloodwork, or neuroimaging for a genuinely simple febrile seizure in a well-appearing, fully recovered child — none of these are indicated and all add cost, radiation, or sedation risk without benefit.[1][5]
- Applying an adult- or general-population lumbar-puncture threshold rather than the age- and immunization-status-specific criteria that actually apply in this age group.[5][1]
- Over-medicalizing a single brief, simple, well-explained febrile seizure — excessive testing or hedged, uncertain-sounding reassurance can itself increase parental anxiety rather than reduce it.
Clinical Decision Algorithm
Drug Tables
How to use this table: Doses are adult doses and require patient-specific confirmation (renal/hepatic function, weight, allergy history). Pediatric dosing is weight-based per the current product monograph unless stated. Drug pricing is intentionally omitted. Select any drug name to open its complete Pharmasist Drug Database page.
Rescue Benzodiazepines — Home/Prehospital Use
Prescribed specifically for a child with a prior prolonged (5 minutes or longer) febrile seizure, or a family living a significant distance from medical care. Always paired with calling EMS — never given as a replacement for it.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Diazepam (rectal gel) | Children: 0.5 mg/kg rectally, maximum 10 mg, as a single rescue dose for a seizure lasting 5 minutes or longer | Sedation, respiratory depression (especially with repeat dosing), ataxia | Additive CNS/respiratory depression with other sedating drugs | 0.5 mg/kg rounds up to the nearest available unit dose; confirm caregiver applicator technique and kit expiry at every follow-up. |
| Midazolam (buccal or intranasal) | Children, buccal: 0.5 mg/kg, maximum 10 mg Children, intranasal: 0.2-0.3 mg/kg, maximum 10 mg | Sedation, respiratory depression, nasal irritation (intranasal route) | Additive CNS/respiratory depression with other sedating drugs | Often preferred over rectal diazepam for ease and dignity of administration; split the intranasal dose between nostrils if the volume is large. |
Rescue Benzodiazepines — In-Hospital IV/IM Use
For an ongoing seizure managed in an emergency or hospital setting. A second dose is reasonable if there is no response within 5 minutes of the first.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Lorazepam (IV) | Children: 0.1 mg/kg IV over 1 minute, maximum 4 mg | Sedation, respiratory depression, hypotension with rapid administration | Additive CNS/respiratory depression with other sedating drugs | Preferred first-line agent when IV access is already established; longer duration of action than diazepam. |
| Diazepam (IV) | Infants: up to 5 mg IV over 2 minutes Older children: up to 10 mg IV over 2 minutes; 0.3 mg/kg | Sedation, respiratory depression, hypotension with rapid administration | Additive CNS/respiratory depression with other sedating drugs | Accepted alternative to lorazepam; redistributes quickly, so re-seizure risk is somewhat higher. |
| Midazolam (IM/buccal/intranasal) | Children: 0.2-0.5 mg/kg depending on route, maximum 10 mg | Sedation, respiratory depression, nasal irritation (intranasal route) | Additive CNS/respiratory depression with other sedating drugs | Preferred first-line route specifically when IV access is not yet available — does not require establishing a line first. |
Antipyretics — Comfort Only, Not Seizure Prevention
Appropriate for fever-related comfort at any point. Explicitly counsel every family that neither agent reduces the chance of another febrile seizure.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Acetaminophen | Children: Weight-based dosing per the current product monograph, typically every 4-6 hours as needed | Hepatotoxicity with overdose or in significant hepatic impairment | None significant at standard doses | First-line antipyretic for comfort; does not prevent febrile seizure recurrence. |
| Ibuprofen | Children over 6 months: Weight-based dosing per the current product monograph, typically every 6-8 hours as needed | GI upset, renal effects with dehydration | Avoid combining with other NSAIDs | Alternative or adjunct to acetaminophen; avoid under 6 months of age; does not prevent recurrence. |
Continuous/Intermittent Prophylaxis — Exceptional Cases Only, Specialist-Directed
Not a routine recommendation after a simple, or even a recurrent, febrile seizure — current guidance is explicit that the risks outweigh the modest benefit. Include here only because a pharmacist may see these prescribed by a pediatric neurologist for genuinely exceptional cases.
| Drug | Dosage | Adverse effects | Drug interactions | Comments |
|---|---|---|---|---|
| Diazepam (intermittent oral/rectal prophylaxis) | Children: Specialist-directed dosing only | Sedation and ataxia common enough to limit routine use; may mask early signs of a more serious illness | Additive CNS/respiratory depression with other sedating drugs | Example published regimen: 5 mg rectally every 8 hours while febrile above 38.4°C; specialist-directed only. |
| Clobazam (intermittent prophylaxis) | Children: Specialist-directed dosing only | Sedation, drowsiness; generally better tolerated than oral diazepam | Additive CNS depression with other sedating drugs | An alternative intermittent regimen reported with fewer side effects than oral diazepam; specialist-directed only. |
| Phenobarbital (continuous prophylaxis) | Children: Specialist-directed dosing only | Sedation, behavioural and cognitive effects with continuous use | Numerous CYP450-mediated interactions | Reduces recurrence but does not change long-term epilepsy risk; not recommended for routine use. |
| Valproic acid (continuous prophylaxis) | Children: Specialist-directed dosing only | Hepatotoxicity risk, particularly in young children; weight gain, tremor | Numerous drug interactions; hepatic enzyme inhibition | Reduces recurrence but does not change long-term epilepsy risk; hepatotoxicity risk makes it a poor routine choice in this age group. |
