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 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 disposal.

1 What Augmentin is and what it
is used for
Augmentin is an antibiotic and works by killing
bacteria that cause infections. It contains two
different medicines called amoxicillin and
clavulanic acid. Amoxicillin belongs to a group
of medicines called “penicillins” that can
sometimes be stopped from working (made
inactive). The other active component
(clavulanic acid) stops this from happening.
Augmentin is used in adults and children to
treat the following infections:
• sinus infections
• urinary tract infections
• skin infections
• dental infections.

• if you are allergic (hypersensitive) to
amoxicillin, clavulanic acid, penicillin or any
of the other ingredients of Augmentin (listed
in section 6)
• if you have ever had a severe allergic
(hypersensitive) reaction to any other
antibiotic. This can include a skin rash or
swelling of the face or neck
• if you have ever had liver problems or
jaundice (yellowing of the skin) when taking
an antibiotic.
