When it comes to managing fever in children there are a few things we have learned. For one, we know that fever in a newborn or infant under 3 year of age requires more immediate attention than fever in older children. We know that infections caused by viruses tend to be the most common causes of fever. And we have learned that the same virus that only causes a runny nose in a child can cause vomiting, congestion, and fever in an infant. Treating a fever often involves the use of medications. Since aspirin is not recommended for fever in children, the use of acetaminophen (Tylenol and other products) and ibuprofen (Advil and other products) are the standard drugs used. However, most health experts do not recommend ibuprofen for infants under six months of age. According to a recent study of children between the ages of 6 months and 3 years of age, alternating between acetaminophen and ibuprofen may be the best approach. Alternating the two drugs compared to either drug used alone provided a more rapid reduction of the child's temperature, resulted in less medicine used, and accounted for less absenteeism from day care.
