Febrile Convulsion

Advice intended for parents/ carers taking their child home after seeing a doctor

If your child:

  • Has another seizure in the current illness lasting more than 5 minutes and/or does not recover rapidly afterwards
  • Develops a rash that does not disappear with pressure (the ‘Glass Test’)
  • Seems difficult to rouse
  • Is fretful or irritable when touched

You need urgent help.

Go to the nearest Hospital Emergency (A&E) Department or phone 999

If your child:

  • Has another febrile convulsion (less than 5 minutes) in the current illness
  • Remains drowsy or lethargic more than an hour after their seizure
  • Seems dehydrated (dry mouth, sunken eyes, no tears, passing less urine than usual)
  • Is not improving after 5 days
  • Seems to be getting worse or if you are worried

You need to contact a doctor or nurse today.

Please ring your GP surgery or call NHS 111 - dial 111

If none of the above features are present

Self care

Continue providing your child’s care at home. If you are still concerned about your child, call NHS 111 – dial 111

Self Care:

  • For practical advice refer to ‘Fever advice sheet’ - download via Healthier Together website: www.what0-18.nhs.uk
  • If your child has a fever and is distressed, you can give them paracetamol (calpol) or ibuprofen. However, remember this might not stop them having a further febrile convulsion and fever is a natural response to infection. Always follow instructions on the bottle and do not exceed daily maximum doses. Never give your child aspirin.
  • Tepid sponging is not recommended – it does not reduce fever and may cause your child discomfort.

Febrile Convulsions (febrile seizures)

  • Occur in about 1 in 20 children, most commonly between 6 months – 3 years of age.
  • They often occur on the first day of a febrile illness. There appears to be no connection between the extent of the fever and convulsions, so they can occur even with mild fevers.
  • Simple febrile convulsions generally last less than 5 minutes, involve the whole body becoming stiff then jerking of all 4 limbs (a tonic clonic seizure) and the child may be sleepy afterwards but should return to their normal self within a couple of hours.
  • 1 in 3 children who have febrile convulsions may have further convulsions with febrile illnesses in the future.
  • Regular treatment for prevention of future seizures is usually not necessary. Febrile convulsions are not epilepsy. There is a small risk of your child developing epilepsy in the future and many parents worry about this, however, most children who have childhood simple febrile convulsions grow out of them and do not develop epilepsy.
  • If your child has had a simple febrile convulsion, has a clear cause for their fever and you and the medical team are happy, they may be cared for at home.

What to do if your child has another convulsion:

  • Place them in the recovery position – on their side, on a soft surface with their face turned to one side. This will stop them swallowing any vomit and keep their airway protected.
  • Stay with your child and try to jot down what time their seizure starts and stops.
  • Do not put anything in your child’s mouth. If the seizure lasts longer than 5 minutes seek immediate medical help – call 999 or go to the nearest A&E.
  • If the seizure lasts less than 5 minutes – phone your GP or NHS 111 for advice if you’re worried
