Fever, Age 4 and Older - Home Treatment

It's easy to become dehydrated when you have a fever.

In the early stages, you may be able to correct mild to moderate dehydration with home treatment measures. It is important to control fluid losses and replace lost fluids.

Adults and children age 12 and older

If you become mildly to moderately dehydrated while working outside or exercising:

  • Stop your activity and rest.
  • Get out of direct sunlight and lie down in a cool spot, such as in the shade or an air-conditioned area.
  • Prop up your feet.
  • Take off any extra clothes.
  • Drink a rehydration drink, water, juice, or sports drink to replace fluids and minerals. Drink 2 qt (2 L) of cool liquids over the next 2 to 4 hours. You should drink at least 10 glasses of liquid a day to replace lost fluids. You can make an inexpensive rehydration drink at home. But do not give this homemade drink to children younger than 12. Measure all ingredients precisely. Small variations can make the drink less effective or even harmful. Mix the following:
    • 1 quart (1 L) purified water
    • ½ teaspoon (2.5 mL) salt
    • 6 teaspoons (30 mL) sugar

Rest and take it easy for 24 hours, and continue to drink a lot of fluids. Although you will probably start feeling better within just a few hours, it may take as long as a day and a half to completely replace the fluid that you lost.

Many people find that taking a lukewarm [80°F (27°C) to 90°F (32°C)] shower or bath makes them feel better when they have a fever. Do not try to take a shower if you are dizzy or unsteady on your feet. Increase the water temperature if you start to shiver. Shivering is a sign that your body is trying to raise its temperature. Do not use rubbing alcohol, ice, or cold water to cool your body.

Dress lightly when you have a fever. This will help your body cool down. Wear light pajamas or a light undershirt. Do not wear very warm clothing or use heavy bed covers. Keep room temperature at 70°F (21°C) or lower.

If you are not able to measure your temperature, you need to look for other symptoms of illness every hour while you have a fever and follow home treatment measures.

Medicine you can buy without a prescription
Try a nonprescription medicine to help treat your fever or pain:

Talk to your child's doctor before switching back and forth between doses of acetaminophen and ibuprofen. When you switch between two medicines, there is a chance your child will get too much medicine.

Safety tips
Be sure to follow these safety tips when you use a nonprescription medicine:
  • Carefully read and follow all directions on the medicine bottle and box.
  • Do not take more than the recommended dose.
  • Do not take a medicine if you have had an allergic reaction to it in the past.
  • If you have been told to avoid a medicine, call your doctor before you take it.
  • If you are or could be pregnant, do not take any medicine other than acetaminophen unless your doctor has told you to.
  • Do not give aspirin to anyone younger than age 20 unless your doctor tells you to.
  • Do not give your child naproxen (such as Aleve) to children younger than age 12 unless your child's doctor tells you to.

Be sure to check your temperature every 2 to 4 hours to make sure home treatment is working.
