Febrile seizures are seizures that occur due to high fever caused by viral infections, and less commonly, bacterial infection. They usually occur in children between the ages of 6 months and 3 years. Febrile seizures most often occur within 24 hours of the onset of a fever and can be the first sign that a child is ill. Some children inherit a family's tendency to have seizures with a fever.
Your doctor may ask these questions to check for this disease:
Medication to stop the seizures is administered through the nose (as sprays), the rectum, or injected. These medications are typically used to treat seizures that last longer than five minutes or if the child has more than one seizure within 24 hours. Medication to reduce the fever and treat infection can also beprescribed.

Q.
Will It Happen Again? Why Febrile Seizures Occur & Medically Approved Next Steps
A.
Most children with febrile seizures recover fully, and while about 30 to 35 percent have another episode, they usually outgrow them by age 5; these seizures are typically triggered by a rapid rise in fever and the long-term risk of epilepsy stays low. There are several factors to consider, including age at the first event and seizure features, plus clear, medically approved next steps for what to do during a seizure and when to seek emergency care. See below for details that can influence your child’s risk and the exact actions to take.

Q.
Was it a Seizure? Why Your Brain is Misfiring and Medically Approved Next Steps
A.
There are several factors to consider: a seizure is a sudden misfire of brain electrical activity that can cause jerking, staring, loss of awareness, or confusion, though fainting, panic, or low blood sugar can look similar, and any episode lasting over 5 minutes or occurring back to back is an emergency. Medically approved next steps are to keep the person safe on their side, time the event, avoid putting anything in the mouth, call emergency services for red flags, and arrange prompt evaluation with labs, EEG, and brain imaging while avoiding driving until cleared; in children, most brief fever related seizures are benign. See below for the complete details on signs, causes, triggers, and step by step actions that could change what you do next.
