Antibiotics are used to treat infections caused by bacteria. They have no
effect against infections caused by viruses.
Sometimes an infection caused by bacteria does not respond to a
course of an antibiotic. One of the commonest reasons for this to
occur is because the bacteria causing the infection are resistant to the
antibiotic that is being taken. This means that they can survive and even
multiply despite the antibiotic.
Bacteria can become resistant to antibiotics for many reasons. Using
antibiotics carefully can help to reduce the chance of bacteria becoming
resistant to them.
When your doctor prescribes a course of an antibiotic it is intended to
treat only your current illness. Paying attention to the following advice
will help prevent the emergence of resistant bacteria that could stop the

specifically for you and you should use it only to treat the infection
for which it was prescribed.
