1. WHAT CO-AMOXICLAV IS AND WHAT IT IS USED FOR
Co-Amoxiclav 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.
Blood and urine tests: If you are 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 you are taking Co-Amoxiclav. This is because
Co-Amoxiclav can affect the results of these types of tests.
Other medicines and Co-Amoxiclav
Tell your doctor or pharmacist if you are taking, have
recently taken or might take any other medicines:
• If you are taking allopurinol (used for gout) with
Co-Amoxiclav, it may be more likely that you'll have an
allergic skin reaction.
• If you are taking probenecid (used for gout), your doctor
may decide to adjust your dose of Co-Amoxiclav.
• If medicines to help stop blood clots (such as warfarin)
are taken with Co-Amoxiclav then extra blood tests
may be needed.
• Co-Amoxiclav can affect how methotrexate (a medicine
used to treat cancer or rheumatic diseases) works.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be
pregnant or are planning to have a baby, ask your doctor
or pharmacist for advice before taking this medicine.
Driving and using machines
Co-Amoxiclav can have side effects and the symptoms
may make you unfit to drive.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE
Patients with kidney or liver problems:
• If you have kidney problems the dose might be
changed. A different strength or a different medicine
may be chosen by your doctor.
• If you have liver problems you may have more frequent
blood tests to check how your liver is working.
Do not take Co-Amoxiclav:
• if you are allergic to amoxicillin, clavulanic acid,
penicillin or any of the other ingredients of this
medicine (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.
Do not take Co-Amoxiclav if any of the above apply to
you. If you are not sure, talk to your doctor or pharmacist
before taking Co-Amoxiclav.
Warnings and precautions
Talk to your doctor or pharmacist before taking
Co-Amoxiclav if you:
• 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 you, talk to
your doctor or pharmacist before taking Co-Amoxiclav.
In some cases, your doctor may investigate the type of
bacteria that is causing your infection.
Depending on the results, you may be given a different
strength of Co-Amoxiclav or a different medicine.
Conditions you need to look out for
Co-Amoxiclav 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 you are taking Co-Amoxiclav, to reduce the risk of
any problems. See 'Conditions you need to look out for'
in Section 4.
Use in children weighing less than 40 kg
Children aged 6 years or less should preferably be
treated with Co-Amoxiclav suspension. Ask your doctor
or pharmacist for advice when giving Co-Amoxiclav
tablets to children weighing less than 40 kg. The tablets
are not suitable for children weighing less than 25 kg.
How to take Co-Amoxiclav:
• Swallow the tablets whole with a glass of water at the
start of a meal or slightly before. Tablets can be broken
along the score line to make them easier to swallow.
You must take both pieces of the tablet at the same time.
• Space the doses evenly during the day, at least 4 hours
apart. Do not take 2 doses in 1 hour.
• Do not take Co-Amoxiclav for more than 2 weeks. If you
still feel unwell you should go back to see the doctor.
If you take more Co-Amoxiclav than you should
If you take too much Co-Amoxiclav, signs might include
an upset stomach (feeling sick, being sick or diarrhoea)
or convulsions. Talk to your doctor as soon as possible.
Take the medicine carton or bottle to show the doctor.
If you forget to take Co-Amoxiclav
If you forget to take a dose, take it as soon as you
remember. You should not take the next dose too soon,
but wait 4 hours before taking the next dose. Do not take
a double dose to make up for a forgotten dose.
If you stop taking Co-Amoxiclav
Keep taking your medicine until the treatment is finished,
even if you feel better. You need every dose to help fight
the infection. If some bacteria survive they can cause the
infection to come back.
If you have any further questions on the use of this
medicine, ask your doctor or pharmacist.

Other sources of information
Detailed information on this medicine is available on
the website of the Medicines and Healthcare products
Regulatory Agency (MHRA).
Antibiotics are used to treat infections caused by
bacteria. They have no effect against infections caused
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
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.
If you get side effects, talk to your doctor or pharmacist.
