Fever in Children: When Your Child Has a Fever
What is a normal temperature?
A normal temperature is about 98.6?F when taken orally (by mouth). Temperatures taken rectally (by rectum) usually run 1?
higher than those taken orally. So a normal temperature is about 99.6?F when taken rectally. Many health care providers
define a fever as an oral temperature above 99.4?F or a rectal temperature above 100.4?F.
How should I take my child's temperature?
The most accurate way to take your child's temperature is orally or rectally with a digital thermometer. In a child younger than
about 4 years, take the temperature rectally. In an older child, take it orally.
? Mercury thermometers should not be used. Mercury is an environmental toxin, and you don't want to risk exposing
your family to it. If you have a mercury thermometer at home, you should remove it and use a digital thermometer.
? Don't bundle your baby or child up too tightly before taking the temperature.
? Never leave your child alone while taking his or her temperature.
? Be sure you use the right thermometer. Read the package instructions to see if you have an oral or rectal
? If you're taking your child's temperature rectally, coat the tip of the thermometer with petroleum jelly (brand name:
Vaseline) and insert it half an inch into the rectum. Hold the thermometer still and do not let go. When the
thermometer beeps, remove it and check the digital reading.
? If you're taking your child's temperature orally, place the end of the thermometer under the tongue and leave it there
until the thermometer beeps. Remove the thermometer and check the digital reading.
? After you're done using the thermometer, wash it in cool, soapy water.
When should I try to lower my child's fever?
Fevers are a sign that the body is fighting an infection. The main reason to treat your child is to make him or her feel better.
When your child is achy and fussy, you may want to give him or her some medicine.
How much medicine is needed to lower a fever?
Acetaminophen (brand names: Children's or Infants' Tylenol) relieves pain and lowers fever. How much acetaminophen your
child may need depends on his or her weight and age, as shown in the chart below. When the age and weight don't match,
use the weight as the main guide. The doses in the chart may be a little higher than what's on the medicine package. Ask
your health care provider if you have any questions. Talk to your health care provider before giving ibuprofen (brand names:
Children's Advil, Children's Motrin) to your child. Your health care provider will tell you the correct dose for your child.

Tips on giving medicine
? Don't give more than 5 doses in 1 day.
? Don't give a baby younger than 4 months old medicine unless your family health care provider tells you to.
? Read labels carefully. Make sure you are giving your child the right amount of medicine.

Why not use aspirin to lower my child's fever?
In rare cases aspirin can cause Reye's syndrome in children who have the flu or the chickenpox. Reye's syndrome is a
serious illness that can lead to death. Because it may be hard to tell if your child has one of these infections, it's best not to
Are there other ways to help my child feel better?
? Give your child plenty to drink to prevent dehydration (not enough fluid in the body) and help the body cool itself.
? Keep your child still and quiet.
? Keep the room temperature at about 70?F to 74?F.
? Dress your child in light cotton pajamas so that body heat can escape.
? If your child is chilled, put on an extra blanket but remove it when the chills stop.
Will a bath help lower my child's fever?
Used together, acetaminophen and a lukewarm bath may help lower a fever. Give the acetaminophen before the bath. If the
bath is given alone, your child may start shivering as his or her body tries to raise its temperature again. This may make your
child feel worse. Don't use alcohol or cold water for baths.
When should I call the health care provider?
If your child has any of the warning signs listed in the box below, call your family health care provider.
Under 1 month old. Call your health care provider right away if your baby's temperature goes over 100.5?F rectally, even if
