Parents frequently avoid giving their children fever medicine before a sick visit because they are afraid it will compromise the doctor’s medical evaluation. In reality, giving a child something to lower her fever before a visit usually makes it easier for doctors to determine what is going on. Fever medicine is not strong enough to mask symptoms, but has the potential to make a young child more cooperative during the visit. There is one caveat to this recommendation, however. NEVER give fever medicine to an infant less than 2 months of age because in this age group, doctors need to assess the baby before the fever is treated.
