Fever In Adults
WHAT YOU NEED TO KNOW:
What is a fever?
A fever is an increase in body temperature above 100.4°F (38°C).
What are common causes of a fever?
The cause of your fever may not be known. This is called fever of unknown origin. It occurs when you have a fever above 100.9˚F (38.3°C) for 3 weeks or more. The following are common causes of fever:
- An infection caused by a virus or bacteria
- An inflammatory disorder, such as arthritis
- Severe withdrawal from alcohol or illegal drugs
What other signs and symptoms may I have?
- Chills and shivers
- Muscle stiffness
- Weight loss
- Night sweats
- Fever that comes and goes
- Fever that is higher in the morning
How is the cause of a fever diagnosed?
Your healthcare provider will ask when your fever began and how high it was. He will ask about other symptoms and examine you for signs of infection. He will feel your neck for lumps and listen to your heart and lungs. Tell him if you recently had surgery or an infection. Tell him if you have any medical conditions, such as diabetes. You may also need blood or urine tests to check for infection. Ask about other tests you may need if blood and urine tests do not explain the cause of your fever.
How is a fever treated?
- Ibuprofen or acetaminophen can help decrease your fever. They are available without a doctor's order. Ask your healthcare provider how much to take and when to take it. Follow directions. These medicines can cause stomach bleeding if not taken correctly. Ibuprofen can cause kidney damage. Acetaminophen can cause liver damage.
- Antibiotics may be given if you have an infection caused by bacteria.
What can I do to manage my fever?
- Take a bath in cool or lukewarm water.
- Use an ice pack wrapped in a small towel or wet a washcloth with cool water. Place the ice pack or wet washcloth on your forehead or the back of your neck.
- Drink more liquids. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you. You may also need to drink an oral rehydration solution (ORS). An ORS has the right amounts of water, salts, and sugar you need to replace body fluids.
