Children
Use anti-infectives with caution; early exposure can lead to early
sensitivity.
Controversy is widespread regarding the use of antibiotics to treat
ear infections, a common pediatric problem. Some believe that the
habitual use of antibiotics for what might well be a viral infection
has contributed greatly to the development of resistant strains.
Because children can have increased susceptibility to the gastro
intestinal and nervous system effects of anti-infectives, monitor
hydration and nutritional status carefully.
