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 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.

2 What you need to know before you give Augmentin
Do not give your child Augmentin:
• if they are allergic to amoxicillin, clavulanic acid, penicillin or any of the
other ingredients of this medicine (listed in section 6).
• if they have ever had a severe allergic reaction to any other antibiotic. This
can include a skin rash or swelling of the face or throat.
• 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
Warnings and Precautions
Check with their doctor, pharmacist or nurse before giving your child
Augmentin if they:

• 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 and urine tests
If your child is having blood tests (such as red blood cell status tests or liver
function tests) or urine tests (for glucose), 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

might take any other 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.

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
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
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.
