Advice/medical education
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
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 antibiotic working.
1. It is very important that you take the
antibiotic at the right dose, at the right
times and for the right number of days.
Read the instructions on the label and if
you do not understand anything ask your
doctor or pharmacist to explain.
2. You should not take an antibiotic unless it
has been prescribed specifically for you
and you should use it only to treat the
infection for which it was prescribed.
3. You should not take antibiotics that have
been prescribed for other people even if
they had an infection that was similar to
4. You should not give antibiotics that were
prescribed for you to other people.
5. If you have any antibiotic left over when
you have taken the course as directed by
your doctor you should take the
remainder to a pharmacy for appropriate
