If you think you have a fever, the first thing to do is take your temperature. Several types of thermometers are available and they work in different ways.

  1. Oral (digital or manual)
  2. Axillary (digital or manual)
  3. Rectal (digital or manual)
  4. Tympanic (digital) - scans ear temperature
  5. Temporal (digital) - scans skin on forehead

Once you have accurately taken your temperature, evaluate whether or not you need to take action to bring it down.

  • In adults, a temperature over about 100 F is considered a fever.
  • In children over 6 months old, a temperature over 101 F generally needs treatment. It is important to consider how your child is acting when deciding the course of action for a fever. If the child is lethargic and eating or drinking poorly, you should treat the fever more aggressively than if the child is playful and active.
  • In children 3 to 6 months old, a temperature over 101 degrees F requires a call to the pediatrician.
  • In children 0 to 3 months old, a rectal temperature over 100.4 F requires a call to the pediatrician.

Once you have decided that you actually have a fever and need to treat it, you should consider your medication options. The most common medications to treat fever are:

If your child is younger than 2 months old and has a fever, you should call your pediatrician before giving him or her any medication.

Tylenol is safe for children over 2 months old.

Advil and Motrin (ibuprofen) are safe for children over 6 months old.

Aspirin should not be given to children under 18 years old unless instructed to by a doctor. It should never be given to a child with cold or flu symptoms because it can cause a serious disease called Reye's Syndrome.

There are a few options if you would prefer to try to reduce a fever without medication. These may also help if medication is not reducing the fever enough.

  • Taking a bath in lukewarm water -- be sure the water is not cold, if it causes shivering, that may cause the internal body temperature to increase.
  • Cool packs or cool rags under the arms, on the forehead and in the groin area -- be sure the packs are not too cold.

What not to do:

Be sure not to wrap the person with a fever in blankets or warm clothes. Although they may feel cold, added layers will only prevent the body temperature from dropping like it should. Dress the person in one layer of comfortable clothes, provided the environmental temperature is comfortable.

Never put someone in an ice bath or use rubbing alcohol on the skin to reduce a person's body temperature. Both of these can be dangerous and are not effective means of bring down a fever.
