Co-Amoxiclav tablets are 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.
Co-Amoxiclav tablets are used in adults and children to treat the following
• middle ear and sinus infections
• respiratory tract infections
• urinary tract infections
• skin and soft tissue infections including dental infections
• bone and joint infections.
Do not take Co-Amoxiclav:
• if you are allergic to amoxicillin, clavulanic acid, penicillin or any of the
other ingredients of your medicine (listed in section 6)

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
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.
