What to Do During a Febrile Seizure (A Calm, Step-by-Step Guide for Parents)

Few moments are more frightening than watching your child's body stiffen and shake while they burn with fever. Your heart slams, your mind goes blank, and the only thought is make it stop. Take a deep breath. A febrile seizure is terrifying to witness, but in the vast majority of cases it is brief, harmless, and over before you finish dialing. Knowing exactly what to do during a febrile seizure — and what not to do — is the single best thing you can give your child in that moment, and it is simpler than you think.

This post is general information, not medical advice, and it does not replace your pediatrician. If your child is having a seizure right now and it has lasted more than five minutes, stop reading and call 911 immediately.

What is a febrile seizure?

A febrile seizure is a convulsion triggered by a rapid rise in body temperature, usually above 100.4°F (38°C), in a child between 6 months and 5 years old. The child may stiffen, twitch or jerk both arms and legs, roll their eyes back, and briefly lose awareness. They are common, affecting roughly 1 in 25 children.

Most febrile seizures happen on the first day of an illness, sometimes before parents even realize the child has a fever. They are not epilepsy, and they are not a sign that something is permanently wrong. They are the immature brain's reaction to a fast temperature change — and almost all children outgrow them completely.

What should I do during a febrile seizure?

Stay calm, lower your child gently to the floor, turn them onto their side, clear the area of hard objects, and start timing the seizure. Do not restrain them or put anything in their mouth. Most seizures stop on their own within a couple of minutes. Stay close and talk softly until it passes.

Here is the step-by-step, in order:

1. Note the time. Glance at a clock or start a timer the instant it begins. Duration is the most important detail you can give a doctor or 911 dispatcher.
2. Lower and position. Ease your child to the floor and roll them onto their side (the recovery position). This keeps the airway clear and lets saliva or vomit drain out of the mouth.
3. Clear the space. Move furniture, toys, and anything hard away so they can't hurt themselves while moving.
4. Loosen tight clothing, especially around the neck.
5. Stay with them and watch. Talk in a low, reassuring voice. Note what the body is doing — which limbs, eyes, color of lips — so you can describe it afterward.
6. Let it run its course. When the shaking stops, keep them on their side as they wake. Children are often sleepy, groggy, or confused for several minutes afterward. That is normal.

If this is your child's first febrile seizure, call your pediatrician or seek medical evaluation afterward even if it stopped quickly — a doctor should confirm the cause of the fever.

What should I NOT do during a febrile seizure?

Never put anything in your child's mouth, never try to hold their body still, and never put them in a bath of cold water to "cool" them. These well-meaning instincts can cause choking, injury, or shock. A child cannot swallow their tongue during a seizure — that is a myth — so there is nothing to "hold down."

The list of don'ts is short but important:

Once your child is awake and alert, you can offer fever medicine to keep them comfortable. Always follow the dosing on the label by your child's weight, and when in doubt, confirm the amount with your pediatrician or pharmacist — Tempy's weight-based reminders are designed to help with exactly this, but they support your judgment rather than replace your pediatrician.

How long does a febrile seizure last?

Most febrile seizures last less than 2 minutes, and the great majority are over within 5 minutes. A seizure shorter than 15 minutes that involves the whole body and does not repeat within 24 hours is called a "simple" febrile seizure — the most common and least worrying type. Anything longer or repeating is "complex" and needs prompt medical review.

This is why timing matters so much. In the moment, two minutes can feel like an eternity, so a clock or phone timer gives you an honest number instead of a panicked guess. That single piece of information shapes every decision that follows.

When should I call 911 for a febrile seizure?

Call 911 immediately if the seizure lasts longer than 5 minutes, if your child has trouble breathing or turns blue around the lips, if a second seizure starts before they fully recover, or if they do not wake up and respond normally after it ends. Also call if the seizure involves only one side of the body.

These are the red flags, and they are not the time to second-guess yourself. Alongside any seizure, treat the following as reasons to call 911 or your pediatrician immediately: a stiff neck, a spreading rash, severe difficulty breathing, persistent vomiting, or unusual limpness and lethargy. And if your baby is under 3 months old and has any fever of 100.4°F (38°C) or higher — with or without a seizure — that always means immediate medical evaluation, with no home management first.

When you call, give the dispatcher three things: how long the seizure lasted, what the body did, and your child's age and rough temperature. You do not need perfect details — your calm description is enough.

Are febrile seizures dangerous or do they cause brain damage?

No. Simple febrile seizures do not cause brain damage, learning problems, or epilepsy, and they do not lower intelligence — even though they look frightening. Decades of research cited by pediatric guidelines show that children who have simple febrile seizures grow up just as healthy as children who never had one.

The fear is completely understandable; the body's violent movements seem like they must be hurting the brain. They are not. The brain is reacting to the fever, not being injured by it. The real risks in the moment are physical — hitting a hard object or choking on saliva — which is exactly why the recovery position and a cleared space matter more than anything else you can do.

Will my child have another febrile seizure?

Maybe — about 1 in 3 children who have one febrile seizure will have another, usually within the next year or two. Recurrence is more likely if the first seizure happened before 18 months of age, if there is a family history, or if the seizure occurred with a relatively low fever. It does not mean the seizures are getting more serious.

Knowing your child is prone to them can actually be reassuring, because you will recognize what is happening next time and respond from a place of preparation instead of panic. Keep a simple record of any seizure — the date, how long it lasted, and the temperature — and share it with your pediatrician. A shared fever log makes those conversations far easier, especially when more than one caregiver is involved.

Can I prevent febrile seizures?

Not reliably — and that surprises many parents. Studies cited by the American Academy of Pediatrics (AAP) show that giving fever medicine early does not prevent febrile seizures, because the seizure is triggered by how fast the temperature rises, not by how high it gets. The goal of fever medicine is comfort, not seizure prevention.

So the most useful "prevention" is preparation: know the steps above, keep your child comfortable and hydrated during fevers, and treat fever medicine as a comfort tool used safely by weight and timing. The FDA and AAP describe general dosing intervals — acetaminophen roughly every 4 to 6 hours and ibuprofen every 6 to 8 hours, with at least a 3-hour gap when alternating — but the exact amount depends on your child's weight, so confirm it with your pediatrician or pharmacist rather than guessing.

The honest bottom line: you cannot always stop a febrile seizure from happening, but you can absolutely control how safely your child gets through one. That is what turns a terrifying night into a manageable one.
