Acetaminophen (Tylenol) to reduce fever interfere with her body’s natural defenses

Always, a child’s high fever is always terrifying to parents. Fever as enemy is deeply ingrained in our cultural memory. But far from being an enemy, a fever is part of the body’s defense against infection. While a fever signals to us that a battle might be going on in a child’s body, the fever is fighting for the child, not against.


Most bacteria and viruses that cause infections thrive at 98.6 degrees F (37 degrees C). Raising the temperature a few degrees can give the body an extra edge. In addition, a fever activates the body’s immune system, accelerating the production of white blood cells, antibodies, and many other infection-fighting agents.


Fever treatment is not likely to be helpful if a child is drinking plenty of fluids, is comfortable, and is able to sleep. Steps should be taken to lower a fever if the child is uncomfortable, vomiting, dehydrated, or having difficulty sleeping. Sleep and hydration are also an important part of healing.


If comfort (not sleep or fluids) is the main reason for reducing a fever, the illness may last an extra day—but the whole experience may be more comfortable.
