Usually defined as a temperature of 100.5 or greater. ( I recommend taking the temperature either rectally or using a temporal scanner thermometer in babies under 12months, then either the temporal or ear thermometer for kids over a year.)

In most cases, fever is usually caused by a viral or bacterial illness and is the body's "appropriate" response to the infection. While this causes fear in many parents, unless your child is under 2 months of age, a fever can be treated at home with Tylenol for babies under 6 months, and Ibuprofen for babies and children 6 months and older. (See dosage chart)

For all babies under 2months, any temperature of 100.5 or greater deserves a call to our office 24 hours a day.

For kids 2 to 6 months, temp of 102 or greater, please call the office. For kids over 6months, unless your child is lethargic, most fevers can be treated with Ibuprofen and see how your child responds. If the fever persists more than 24 hours or there are other symptoms present, please call for appointment.

As many of my patients have heard in the past, I am more concerned about how the child looks with a fever, rather than the height of the temperature itself. There is not necessarily a maximum height that needs to have immediate attention-unless your child is under 2 months.

Many parents think that a high temperature will cause "brain damage." This is not true. It is possible to have brain injury from "environmental heat stroke-very hot days with strenuous activity, but not from a temperature associated with an illness. About .5-1 % of all children may have a seizure associated with a high fever, but this cannot be predicted based upon the height of the fever and is often thought to be related to the rapid rise in the fever and if there is a family history of seizures with fever.
