1 What Augmentin is and what it is
used for


Body text size: 8.3pt

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 babies and children to
treat the following infections:
• middle ear and sinus infections
• respiratory tract infections
• urinary tract infections
• skin and soft tissue infections including
dental infections
• bone and joint infections.

• if they are allergic to amoxicillin, clavulanic
acid or any of the other ingredients of
Augmentin (listed in section 6)
• if they 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 they have ever had liver problems or
jaundice (yellowing of the skin) when taking
an antibiotic.
➜➜Do not give Augmentin to your child if any
of the above apply to your child. If you are
not sure, talk to their doctor or pharmacist
before giving Augmentin.

Take special care with Augmentin

Check with their doctor, pharmacist or nurse
before giving your child this medicine if they:
• have glandular fever
• are being treated for liver or kidney problems
• are not passing water regularly.
If you are not sure if any of the above apply to
your child, talk to their doctor or pharmacist
before giving Augmentin.
In some cases, your doctor may investigate the
type of bacteria that is causing your child’s
infection. Depending on the results, your child
may be given a different strength of
Augmentin or a different medicine.

Conditions you need to look out for

Augmentin can make some existing conditions
worse, or cause serious side effects. These
include allergic reactions, convulsions (fits) and
inflammation of the large intestine. You must
look out for certain symptoms while your child
is taking Augmentin, to reduce the risk of any
problems. See ‘Conditions you need to look
out for’ in section 4.

Blood or urine tests

If your child is having blood tests (such as red
blood cell status tests or liver function tests) or
urine tests, let the doctor or nurse know that
they are taking Augmentin. This is because
Augmentin can affect the results of these types
of tests.

Other medicines and Augmentin

Tell your doctor or pharmacist if your child is
taking or has recently taken any other medicines.
This includes medicines that can be bought
without a prescription and herbal medicines.
• If your child is taking allopurinol (used for
gout) with Augmentin, it may be more likely
that they will have an allergic skin reaction.
• If your child is taking probenecid (used for
gout), your doctor may decide to adjust the
dose of Augmentin.
• If medicines to help stop blood clots (such as
warfarin) are taken with Augmentin then
extra blood tests may be needed.
• Augmentin can affect how methotrexate
(a medicine used to treat cancer or
rheumatic diseases) works.

mofetil (a medicine used to prevent the
rejection of transplanted organs) works.

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 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 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 disposal.
