Febrile Seizures in Children: Causes, First Aid & When to Rush to the Hospital
Watching your child's body stiffen or jerk during a fever is one of the most frightening moments a parent can face. Here's exactly what's happening, what to do in the first five minutes, and when it's truly an emergency.
Your child had a fever an hour ago — now their eyes have rolled back, their arms and legs are jerking, and they aren't responding to you. It's one of the most alarming things a parent can witness, and in the moment it can feel like it's lasting forever. The good news: febrile seizures are far more common than most parents realise, and the vast majority are brief and leave no lasting harm. This guide from Srirama Children's Hospital, Mancherial explains what's happening, what to do right now, and when it's a genuine emergency.
What Exactly Is a Febrile Seizure?
A febrile seizure is a convulsion triggered by a rapid rise in body temperature, most often in the first day of a fever — sometimes even before a parent realises the child is unwell. It happens because a young, still-developing brain can be temporarily sensitive to sudden spikes in temperature, causing a brief burst of abnormal electrical activity.
Febrile seizures are common: they affect roughly 2–5% of children, typically between 6 months and 5 years of age, with the peak around 12–18 months. Despite how alarming they look, a simple febrile seizure does not cause brain damage, and it does not mean your child has epilepsy.
Simple vs. Complex Febrile Seizures
Simple Febrile Seizure
Lasts less than 15 minutes, involves the whole body (both arms and legs), and does not recur within 24 hours. This accounts for about 80% of febrile seizures and carries an excellent outlook.
Complex Febrile Seizure
Lasts longer than 15 minutes, affects only one side of the body, or recurs within the same 24-hour period. This needs more thorough evaluation to rule out other causes.
Recurrent Febrile Seizures
About 1 in 3 children will have another febrile seizure during a future fever. Recurrence is more likely in children who had their first seizure before 15 months of age.
What a Febrile Seizure Actually Looks Like
Febrile seizures can look different from child to child, but the most common pattern includes:
- Stiffening: Arms, legs, or the whole body suddenly go rigid.
- Jerking movements: Rhythmic twitching of the arms and legs on both sides.
- Eye rolling: Eyes may roll back or stare fixed to one side.
- Loss of awareness: Your child will not respond to their name or touch during the episode.
- Bluish lips: Breathing can look irregular for a few seconds — this is common and usually resolves once the seizure ends.
- Sleepiness afterward: Most children are drowsy or confused for a few minutes to an hour after the seizure stops.
What To Do in the First 5 Minutes
If your child begins seizing, staying calm and following these steps in order will keep them safe:
Note the time
Check a clock or your phone the moment the seizure starts. Timing it accurately is the single most important thing you can do.
Lay your child on their side
Gently place them on a flat surface on their side (the recovery position) to help keep their airway clear and prevent choking.
Clear the area
Move away any hard, sharp, or hot objects nearby. Loosen tight clothing around the neck.
Do not restrain or put anything in the mouth
Never hold your child down or try to stop the jerking. Never place a spoon, your fingers, or any object in their mouth — this can cause injury.
Stay close and watch closely
Stay with your child, speak calmly, and observe exactly what the movements look like — this detail helps the doctor afterward.
Call for help if it passes 5 minutes
If the seizure continues past 5 minutes, or a second seizure starts before your child recovers, call emergency services (108) immediately.
After it stops, get medical evaluation
Even a brief, simple seizure needs to be checked by a doctor the same day to confirm the cause of the fever and rule out other conditions.
Call Emergency Services (108) Immediately If:
- The seizure lasts longer than 5 minutes
- A second seizure starts before your child fully recovers
- Your child has trouble breathing or their lips stay blue after the seizure ends
- This is your child's first-ever seizure
- Your child was injured during the seizure (a fall, a bump to the head)
- Your child does not wake up or does not return to normal alertness within an hour
- You suspect the child may have swallowed something or vomited during the seizure
- Your child is younger than 6 months, or older than 5 years, and has a first seizure
Simple vs. Complex Febrile Seizure — At a Glance
| Feature | Simple Febrile Seizure | Complex Febrile Seizure |
|---|---|---|
| Duration | Under 15 minutes (usually under 5) | Over 15 minutes |
| Body involvement | Whole body, both sides equally | One side of the body only |
| Recurrence | Does not repeat within 24 hours | Occurs more than once in 24 hours |
| Frequency | About 80% of all febrile seizures | About 20% of all febrile seizures |
| Next step | Same-day pediatric check | Emergency evaluation |
What Triggers a Febrile Seizure?
Febrile seizures are usually triggered by common childhood illnesses, not by how high the fever climbs. In fact, it's often the speed at which temperature rises, not the peak number, that matters most:
- 🔴 Common viral infections (colds, flu, roseola)
- 🔴 Ear infections
- 🔴 Throat infections
- 🔴 Vaccination-related fever (uncommon, and not a reason to avoid vaccination)
- 🔴 A family history of febrile seizures increases the likelihood
Reassuring Facts Every Parent Should Know
Febrile seizures do not cause brain damage, learning problems, or developmental delay. They are not the same as epilepsy, and having one does not mean your child will develop epilepsy later. Most children fully outgrow the tendency by age 5–6.
Can You Prevent a Febrile Seizure?
Because seizures are often triggered by the speed of a temperature rise rather than the peak reading, they can't always be prevented — but these steps support your child's comfort and recovery:
Give weight-appropriate paracetamol or ibuprofen for comfort. Fever medicine has not been proven to prevent febrile seizures, but it helps your child feel better.
Offer fluids regularly during any illness with fever to support overall recovery.
If your child has had a febrile seizure before, mention it to your pediatrician at the very start of any future fever.
Vaccines protect against several illnesses that can cause high fevers, and the seizure risk from vaccination itself is very small.
If your child is prone to febrile seizures, ask your pediatrician for a written action plan you can follow calmly if it happens again.
Heavy blankets or layers trap heat and can contribute to a faster temperature rise — dress your child lightly instead.
What Happens at the Hospital After a Febrile Seizure
| Situation | What the Doctor Checks | Typical Next Step |
|---|---|---|
| First simple febrile seizure | Physical exam, source of fever, vital signs | Observation, guidance for parents, discharge home if well |
| Complex febrile seizure | Neurological exam, blood tests, sometimes EEG or imaging | Extended observation, specialist referral if needed |
| Seizure lasting over 5 minutes | Emergency airway and vital sign management | Medication to stop the seizure, admission for monitoring |
| Under 12 months old | Careful evaluation to rule out other causes (e.g., meningitis) | May include further testing depending on findings |
| Recurrent febrile seizures | Review of seizure pattern and family history | Parent education, individualized action plan, pediatric neurology referral if indicated |

Frequently Asked Questions (FAQs)
Most febrile seizures are brief and do not cause any lasting harm to the brain. They can be frightening to watch, but a simple febrile seizure lasting under 5 minutes is generally not dangerous, though it always needs a medical evaluation afterward.
If a seizure lasts longer than 5 minutes, or a second seizure begins before your child fully recovers, call emergency services immediately. This is considered a medical emergency.
About 1 in 3 children who have one febrile seizure will have another during a future fever, usually within the next year or two. Most children outgrow the tendency by age 5 or 6.
Simple febrile seizures do not cause epilepsy. The overall risk of developing epilepsy later is only slightly higher than in the general population, and most children with febrile seizures never go on to develop it.
Fever-reducing medicine helps your child feel more comfortable, but it has not been shown to reliably prevent febrile seizures. It's still worth giving at the correct weight-based dose for comfort during illness.
No. Do not sponge, bathe, or apply ice to your child during an active seizure. Focus only on keeping them safe on their side until the seizure passes, then seek medical evaluation.
Yes — even a brief, simple febrile seizure should be evaluated by a doctor the same day to identify the cause of the fever and confirm your child has recovered normally. A seizure lasting over 5 minutes needs emergency care immediately.
Describe how long the seizure lasted, which body parts moved, whether it affected one side or both, how your child behaved afterward, the fever's highest temperature, and any family history of seizures.
