A Guide to Fevers & How to Treat Them

A fever is a rise in body temperature, and is usually the sing of an infection. Fevers themselves are generally harmless and don’t require medical intervention beyond treatment for the underlying cause. Occasionally though, a fever can get too high and risk the patient’s wellbeing. Here’s what you should know about fevers.

What Temperature is Considered a Fever?

The average human body temperature is 98.6 F (37 C), but the temperature can vary between 97 F (36.1 C) and 99 F (37.2) naturally. Your activity levels, age, and the time of day can affect your body’s temperature. Frequently, older individuals have a lower body temperature than younger people.

The following temperatures may indicate a fever:

  • Rectal, ear, or temporal artery temperature: 100.4 F (38 C) or higher.
  • Oral temperature: 100 F (37.8 C) or higher.
  • Armpit temperature of 99 F (37.2 C) or higher

How Do I Treat a Fever?

Typically, most treatment for fevers involve keeping the patient hydrated and comfortable. The fever may be a reaction to a more serious issue, so be sure to see your doctor if the fever doesn’t dissipate within a few days or continues to climb. Individuals with fevers may not look or act particularly ill, unless the fever is more than a few degrees of difference from normal body temperature.

Treatments for fevers include:

  • Encouraging the patient to stay hydrated, and offering them clear fluids such as water, broth, tea, and clear juices.
  • Dressing the patient in lightweight clothing to prevent overheating.
  • Covering the patient in a light blanket if they are experiencing chills.
  • Giving the patient a pain reliever, such as acetaminophen (Tylenol) or ibuprofen (Advil). If the patient is a child, consult their pediatrician and all dosage instructions.

When to Seek Medical Care

Serious fevers can cause physical damage, and they are often an indication of a severe infection that may require medical treatment. Depending on the age of the patient, the signs of a more serious illness can vary. If the patient is displaying any of these symptoms, you should seek medical advice.


  • Fussiness or abnormal behavior that doesn’t subside after medication

  • Stiff neck or a headache

If your child is less than 3 months of age and has a fever, they should receive immediate medical attention.
