General advice regarding the use of antibiotics
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
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 yours.
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
