Febrile Seizure First Aid | Symptoms, What to Do & When to Call 911

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.

Type	Simple Febrile Seizure	Complex Febrile Seizure
Duration	Less than 15 minutes (usually 2-3 min)	15 minutes or longer
Seizure Pattern	Generalized, symmetrical	Focal or asymmetrical
Recurrence within 24 hours	None	Possible
Prognosis	Excellent	Requires 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. After the Seizure Stops

• Loosen tight clothing
• Give a fever reducer only once the seizure has fully stopped and your child seems uncomfortable (it will not prevent another seizure)
• Do not sponge your child to bring the temperature down

When to Call 911

If the seizure is still going on, or your child stays unconscious after it stops, call 911 instead of driving in yourself.

Call 911 Immediately If:

• Seizure lasts more than 5 minutes
• Seizure stops and starts again
• Child doesn't wake up or respond to you once the seizure stops
• Any difficulty breathing
• Lips remain blue

Go to the ER Right Away, Even If the Seizure Has Stopped, If:

• This is your child's first febrile seizure
• Baby is under 6 months old
• The stiffness or twitching was on only one side of the body
• Your child has more than one seizure within 24 hours
• Your child is much sleepier than usual for more than 1 hour after the seizure

See a Doctor the Same Day If:

• Cause of fever is unknown
• You're worried or anxious

If this is your child's first febrile seizure, get them checked at the ER right away, even if they seem 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

Fever reducers cannot prevent febrile seizures. When your child has a fever, focus on keeping them comfortable, and if seizures keep coming back, talk with your doctor about preventive medicine.

Fever Management

• Use a fever reducer only when your child seems uncomfortable, not to head off a seizure
• 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

Prevention Method	Effectiveness	Notes
Early fever reducer	No preventive effect	Do not use it to prevent seizures
Temperature monitoring	Helpful	Early detection of fever rise
Preventive diazepam	Effective	Requires prescription, consider side effects

Febrile Seizure vs Epilepsy

Febrile seizures and epilepsy are different conditions.

Feature	Febrile Seizure	Epilepsy
Cause	Temporary reaction to high fever	Abnormal brain electrical activity
Trigger	Only with fever	Can occur without fever
Age	6 months to 5 years	Any age
Prognosis	Usually outgrown	Requires ongoing management

Frequently Asked Questions (FAQ)

Q: At what age do febrile seizures usually happen?
A: Febrile seizures mainly occur in children between 6 months and 5 years old. They happen when the brain temporarily overreacts to a rapid rise in body temperature, usually with fevers above 38°C (100.4°F). They can be triggered by various infections such as colds, ear infections, or stomach bugs.

Q: How do I give first aid if my baby has a febrile seizure?
A: Lay your child on a flat, safe surface, remove nearby dangerous objects, and turn their head to the side so vomit or saliva does not block the airway. Do not put anything in their mouth and do not give water or medicine during the seizure. Note when it started and record a video if possible, since it helps the doctor.

Q: What should I do if a febrile seizure lasts more than 5 minutes?
A: Call 911 immediately if the seizure lasts more than 5 minutes, stops and starts again, or your child does not wake up or respond once it ends. Trouble breathing or lips that stay blue are also emergencies. A first febrile seizure, or any seizure in a baby under 6 months, needs an ER check right away, even if it was short.

Q: Will a febrile seizure cause lasting harm?
A: Most simple febrile seizures have no effect on intelligence or development, and the risk of brain damage is extremely low. The chance of developing epilepsy is about 2-4%, only slightly higher than the 1% in the general population. However, about 30-40% of children have another febrile seizure later.
