Childhood Fevers: When Are They A Cause Of Concern? Information supplied by Waukesha Memorial Hospital Fever prompts many visits to pediatricians, but when is fever worrisome? Often, fevers are caused by viral infections that get better without treatment, says pediatrician Meg Scandura, MD. Fevers can indicate bacterial infections (requiring antibiotics), and can accompany inflammation or drug reactions. Childhood fevers should never be ignored, Scandura says. Here are some simple guidelines. Contact the pediatrician if your child experiences any of the following: Has a rectal temperature above 100.4º F and is less than three months old. Has a temperature of 104º F or higher at any age. Has had a persistent fever for three days or is not responding to fever reducing medicine. Persistent vomiting or abdominal pain. Unusual sleepiness Severe headache Severe sore throat or inability to swallow. Difficulty breathing Pain with urination Provide comfort measures: Give your child a fever reducing medication such as acetaminophen, the active ingredient in Tylenol. If your baby is under 6 months old, do not administer any medication before speaking with the doctor. Never give a child aspirin, as it is associated with Reye's syndrome, a serious condition that can lead to coma and death. Give plenty of fluids to prevent dehydration. To prevent overheating, dress your child in loose, light clothing. If your child feels chilled, cover him or her with a blanket. Lukewarm sponge baths (water only, do not give alcohol baths) can provide comfort to a child whose fever is not responding to acetaminophen, or who cannot take medication.
