When your baby suddenly develops a fever and starts having convulsions, it can be terrifying for parents. Febrile seizures are common in children between 6 months and 5 years old, and most children recover completely without any lasting effects. This guide covers febrile seizure symptoms, first aid procedures, when to seek emergency care, and how to prevent recurrence.

What Is a Febrile Seizure?

A febrile seizure occurs when the brain temporarily overreacts to a rapid rise in body temperature. It typically happens with fevers above 38°C (100.4°F) and can be triggered by various infections such as colds, ear infections, or stomach bugs.

TypeSimple Febrile SeizureComplex Febrile Seizure
DurationLess than 15 minutes (usually 2-3 min)15 minutes or longer
Seizure PatternGeneralized, symmetricalFocal or asymmetrical
Recurrence within 24 hoursNonePossible
PrognosisExcellentRequires further evaluation
The majority of febrile seizures (about 70-75%) are simple febrile seizures, which resolve completely without any lasting effects.

Febrile Seizure Symptoms

During a febrile seizure, your child may show these signs:

Main Symptoms

  • Sudden loss of consciousness
  • Eyes rolling back or fixed stare
  • Body stiffening (tonic phase)
  • Rhythmic jerking of arms and legs (clonic phase)
  • Blue lips (cyanosis)
  • Drooling or foaming at the mouth
  • Irregular breathing

After the Seizure

  • Limp and sleepy
  • Temporarily unresponsive
  • Fussy or crying
  • Returns to normal within 30 minutes to 1 hour

Febrile Seizure First Aid

If your baby has a febrile seizure, stay calm and follow these steps:

1. Place Your Child on a Safe Surface

  • Lay them on a flat, safe surface
  • Remove nearby dangerous objects
  • Place something soft under their head

2. Position on Their Side (Recovery Position)

  • Prevents choking on vomit or saliva
  • Turn their head to the side

3. What NOT to Do

  • Don't put anything in their mouth
  • Don't give water or medicine during the seizure
  • Don't hold them down or shake them
  • Don't try to stop the seizure forcefully

4. Time the Seizure

  • Note when it started
  • Observe the pattern (symmetrical or not)
  • Record video if possible (helpful for doctors)

5. Lower the Fever (After Seizure Stops)

  • Loosen tight clothing
  • Give fever reducer (only after seizure ends)
  • Sponge with lukewarm water

When to Call 911

Seek emergency care immediately in these situations:

Call 911 Immediately If:

  • Seizure lasts more than 5 minutes
  • Seizure stops and starts again
  • Child doesn't regain consciousness after 30 minutes
  • Severe breathing difficulty
  • Lips remain blue

See a Doctor the Same Day If:

  • This is your child's first febrile seizure
  • Baby is under 6 months old
  • Cause of fever is unknown
  • You're worried or anxious
If this is your child's first febrile seizure, always see a doctor afterward, even if your child seems fine.

Febrile Seizure Prognosis and Long-term Effects

Many parents worry about lasting effects, but the prognosis for most febrile seizures is excellent.

Simple Febrile Seizure Outcomes

  • No effect on intelligence or development
  • Extremely low risk of brain damage
  • Risk of developing epilepsy: about 2-4% (vs 1% general population)

Recurrence Risk

  • About 30-40% have another febrile seizure
  • Higher risk factors include:
    • First seizure before 12 months of age
    • Family history of febrile seizures
    • Seizure with relatively low fever
    • Seizure within 1 hour of fever onset

Preventing Febrile Seizures

While febrile seizures cannot be completely prevented, these measures may help:

Fever Management

  • Give fever reducer at first signs of fever
  • Monitor temperature frequently
  • Ensure adequate fluid intake

Preventive Medication (Diazepam)

  • For children with frequent recurrences
  • Given when fever starts, as prescribed
  • Not recommended for all children
