Facts about fever
Fever is a common problem with illness in children. It often results from an infection caused by a virus or bacteria (germ). Some infections are serious and need to be cared for in the hospital. Many others can be cared for at home.
NOTE: For babies less than 12 months old – take the temperature in the rectum (the opening where the bowel movement or stool comes out). Other methods are not as accurate in infants.
Should I treat my child's fever?
Your child's doctor will talk with you about specific care for your child. In general, not all fevers need to be treated. Some reasons to treat a fever include if your child:
- Is not comfortable when the fever is high.
- Will not drink enough fluids when the fever is high.
How do I treat a fever?
Your child's doctor will talk with you about specific care for your child. Some general guidelines to follow include:
- Give acetaminophen (Tylenol® or other less costly store brand). Follow the directions on the box carefully or ask your child's doctor how much medicine to give.
- This is often the only medicine a child with fever needs to feel better.
- It may take 60 to 90 minutes for these medicines to work.
- Do not give acetaminophen to babies under 3 months of age without a doctor's order.
- Do not give your child more than 5 doses of acetaminophen in a 24-hour period.
- If you give your child the correct dose of acetaminophen every four hours and he is still not comfortable, you may give him ibuprofen (Motrin®, Advil® or other less costly store brand) every six hours instead. If you do this, stop giving him the acetaminophen.
- Do not give ibuprofen to babies less than 6 months of age without a doctor's order.
- If your child has chickenpox, asthma, kidney problems or bleeding problems, ask your child's doctor before giving ibuprofen.
- Follow the directions on the box carefully or ask his doctor how much medicine to give.
- Do not give any aspirin.
- Check with your child's doctor or pharmacist before giving acetaminophen or ibuprofen with other medicines. This includes over-the-counter medicines.
- Tell your child's doctor if your child is taking any vitamins, herbal products or other supplements or home remedies.
- Dress your child very lightly. Do not bundle or cover with a blanket.
- Give him lots of cool liquids.
