Dr. Gideon Koren, medschoolforparents.com Expert explains the use of antibiotics.
It is important to understand that antibiotics kill bacteria but NOT viruses and 90% of all infections in children are not from bacteria. This means it is important to give antibiotics only when needed.
There are cases when antibiotics are important. For example if bacteria cause middle ear infections, infection of tonsils, and pneumonia. Unneeded antibiotics are a risk because they build resistance to antibiotics, making antibiotics less useful when they are actually needed.
