Steps to follow:

Before we tell you how to lower a fever in adults, you should know that if you have an infant 3 months old or younger with fever, you should call a doctor immediately, even if the baby does not present any other symptoms. For children older than 2 years old with fevers 38.9ºC (102.02ºF) and higher, children's medication may be used to reduce the discomfort. Always avoid giving aspirin to children, as it could cause severe adverse effects. Find out how to take a baby's temperature and what is the normal temperature in babies.

For adults, if your fever is below 38.9ºC (102.02ºF), medication is not needed. Simply get plenty of rest and drink a lot of fluids. A cold bath and drinking cold fluids may help with reducing your temperature.


Closely control fever. Take your temperature regularly to determine if your condition is worsening. If the fever continues to rise to 39.0ºC or higher (102.2ºF) or shows no signs of decline, take acetaminophen or ibuprofen to help reduce it. This will also help alleviate some of the pain and other bothersome symptoms associated with fever.


Stay hydrated. The body needs fluids to fight whatever is causing the fever. If your stomach is upset and struggles to keep liquids down try sucking on ice or drinking ginger ale or soda. The replacement of fluids is especially important if you experience vomiting or diarrhea.

Suck on an ice cube or fruit ice cream. Apart from drinking water, follow a liquid diet with soups and jelly. You can have solid food as you start to feel better.


Position yourself as comfortably as possible so that your body can fight off the fever. Wear lightweight clothing and keep the room cool. Try taking a tepid bath or running a cold sponge or cloth on yourself.


Consult your doctor if the fever is very high or if it lasts for several days. A temperature of over 39° C (102.2ºF) is generally considered very high. You should also seek medical attention if you experience confusion, sharp headache, painful urination, stiff neck, seizures, difficulty breathing, vomiting or diarrhea.
