Typically, fever is nothing to fear. It is the body’s natural sign that it may be fighting off illness or inflammation is present. Fever in a newborn, however, is something not to take lightly. Infants under 6 weeks old do not have well developed immune systems. Although often times fever is caused simply by over-bundling or a viral illness, if the fever is caused by a bacteria, it may progress to a bacterial blood stream infection and can even quickly lead to meningitis.

If your infant (under 6 weeks old) runs a fever, you should call the office or the physician-on-call immediately. For children older than 6 weeks, fever is not typically an emergency, however please do not hesitate to get in touch with the office if you have any concerns. Many fevers are a result of viral infections, and a simple dose of Acetaminophen (Tylenol) or Ibuprofen (Motrin or Advil), if the child is uncomfortable, is all they need.

Please note, children under 6 months should only receive Tylenol, but if older than 6 months, either is fine. If the fever continues to be present or rise when the fever-reducer wears off, an office visit is warranted to look for an infectious source that may need treatment with antibiotics. Acetaminophen (Tylenol) and Ibuprofen (Motrin or Advil) typically can be given up to every 6 hours as needed. You may alternate Acetaminophen (Tylenol) or Ibuprofen (Motrin or Advil) every 3 hours.
