How to Get Rid of a Fever

Medically reviewed by David Nazarian, MD

Last Updated: September 28, 2024 Approved

A fever is not an illness in itself, but is usually a sign that the body is working to fight off an illness of some kind. It is usually not a good idea to try to get rid of your fever entirely because it may interrupt the body's attack against the virus or bacteria that it is trying to fight. Depending on what is causing your fever, you may want to let it run its course or you may want to seek medical treatment for the underlying illness. If your fever is making you uncomfortable or if you're concerned about a fever running too high, there are plenty of methods you can use to bring it down.

Taking Good Care of Yourself

1
Undress a bit. Although you might feel cold when you have a fever, your body temperature is actually too high, and you will need to lower it in order to feel warmer. Allow your body to release excess heat by wearing only a thin layer of clothing and covering up with a thin blanket or sheet if necessary.^{[1]

- Piling on sweatshirts and blankets can actually be dangerous if you have a fever because it can raise your body temperature even more.
2
Set the temperature to a comfortable level. Keeping the room temperature excessively high may prevent your body from releasing its excess heat, but your room should also not be too cold. Shivering is your body's way of naturally increasing its internal temperature, so if your room is so cold that you are shivering, you will only be making your fever worse.^{[2]

Cool yourself down with water. Dampening your skin is a great way to lower your body temperature, but you should make sure that you are careful not to make yourself too cold. Apply a damp towel to your forehead and extremities or sponge yourself down with some warm water. The water should always be lukewarm to prevent your body from shivering in response.^{[3]

Take over-the-counter medications. If your fever is making you uncomfortable, you can take over-the-counter fever reducers, such as acetaminophen (Tylenol) or ibuprofen.^{[4]

- Keep in mind that these medications might make you feel better, but they will not treat the underlying cause of your fever. If you suspect that you have some kind of bacterial infection, it is extremely important that you see your doctor and take all of your prescribed medications.
5
Get plenty of rest. Help your body in its battle by getting extra sleep and spending as much time lounging around as you can. This does not mean that you have to stay in bed all day, but try to avoid exerting yourself.^{[8]

Treating the Cause

1
Assess your symptoms. In order to determine the best way to get rid of your fever, it is important to know what is causing it. Make note of all the symptoms you are experiencing. If you have any symptoms that cannot be explained by a common virus, such as a sore throat or earache, see a doctor for a diagnosis.^{[15]

- Seek immediate medical attention if you experience symptoms such as confusion, difficulty moving or breathing, blue lips or nails, seizures, stiff neck, or severe headaches.
- A high fever in a child can trigger a febrile seizure, which is usually harmless and generally does not indicate a more serious health problem; however, you should take your child to the doctor as soon as possible following her first febrile seizure. Call an ambulance if the seizure lasts longer than a few minutes. Otherwise, drive your child to the emergency room as soon as the seizure is over.^{[16]

2
Take antibiotics. If you are diagnosed with a bacterial infection, such as strep throat or a urinary tract infection, your doctor will prescribe an antibiotic medication to help treat it. Take your medication as directed and your fever, along with your other symptoms, should disappear within a few days.^{[17]

- Take your antibiotics as prescribed until they are gone —even if you start feeling better. This ensures you truly eradicate the bacteria and prevents antibiotic resistance in the future.
3
Know when a fever is too high. Fevers are usually nothing to worry about, but they can be dangerous if they run too high or if they persist for too long. Seek medical attention right away if you are worried that you or your child might have a fever that is too high.^{[19]

- For children three months and younger, seek medical treatment for a fever of 100.4°F (38°C) or higher.
- For children between three and 12 months of age, seek medical treatment for a fever of 102.2°F (39°C) or higher.
- For older children and adults, seek medical treatment for a fever of 105°F (40.6°C) or higher that does not readily subside with treatment.
- A prolonged fever over 107.6°F (42°C) can cause the body to start shutting down and may lead to brain damage if not treated.
- You should also seek medical treatment for any fever that persists for longer than 48 to 72 hours, or longer than 24 to 48 hours for children under the age of two.
4
Get treatment for chronic conditions. Fevers can also be caused by chronic autoimmune and inflammatory conditions, such as lupus, vasculitis, and ulcerative colitis. The best way to treat these kinds of fevers is to work with your doctor to create a plan for treating your underlying condition.^{[20]

5
Get immediate treatment for fevers caused by environmental factors. If you experience a fever after exposure to extreme heat, you may be suffering from hyperthermia or heat stroke. In this case, your body needs to be cooled down as quickly as possible.^{[21]

Tips

Remember that your fever is working to help kill off an infection in your body, so you don't want to get rid of it completely. It is reasonable to lower a fever if you are extremely uncomfortable, but most fevers do not require treatment.^{[22]

If your child is old enough to communicate their symptoms, make sure you listen to them. He or she knows what's going on and how it feels.
