What to Do About a Fever (High Temperature)

A fever, or high body temperature, is often the body’s natural response to infection and a sign that the immune system is working. While it can be concerning, most fevers are not harmful and resolve on their own. To manage a fever, ensure the person stays hydrated with water, clear fluids, or electrolyte solutions, and dress them in light, comfortable clothing. Over-the-counter medications like acetaminophen or ibuprofen can help reduce the fever and alleviate discomfort. Rest is essential for recovery. However, if the fever is very high, lasts more than a few days, or is accompanied by severe symptoms, it’s important to seek medical advice promptly.

Managing a Fever in Children

Parents often worry when their child’s temperature rises, but a fever usually isn’t harmful. In fact, it’s often the body’s natural response to fighting infections.

Signs & Symptoms of a Fever

A child with a fever may display the following symptoms:

  • Fussiness
  • Discomfort
  • Warm skin to the touch
  • Flushed appearance
  • Sweating

What to Do for a Fever

If your baby is under 3 months old and has a temperature of 100.4°F (38°C) or higher, contact the doctor immediately. If you cannot reach the doctor, go to the emergency room.

Keep children with a fever at home from school or childcare until their temperature has returned to normal for at least 24 hours. If your child is uncomfortable, here are some ways to help:

  • Offer fluids to prevent dehydration.
  • Administer acetaminophen or ibuprofen according to the doctor’s instructions. Do not give aspirin, as it is linked to a rare but serious illness called Reye syndrome.
  • Avoid using rubbing alcohol or cold baths to lower the fever.
  • Dress your child in lightweight clothing and cover them with a light sheet or blanket.
  • Allow them to eat if they want, but don’t force them if they have no appetite.
  • If your child is vomiting or has diarrhea, consult the doctor about using a children’s oral rehydration solution.
  • Ensure plenty of rest for your child.

When to Seek Medical Care

Seek medical attention if:

  • Your baby is under 3 months old with a temperature of 100.4°F (38°C) or higher.
  • An older child with a fever:
    • Appears very ill
    • Develops a rash
    • Has persistent diarrhea and/or repeated vomiting
    • Shows signs of dehydration (reduced urination, lack of tears when crying, decreased alertness, and activity)
    • Has a fever lasting more than 5 days
    • Has a chronic medical condition, such as sickle cell disease or cancer

Can Fevers Be Prevented?

All children experience fevers occasionally, and they usually recover within a few days. The main goal is to keep your child comfortable until the fever subsides and seek medical care if necessary.
