1. What Co-amoxiclav film-coated tablets
are and what are they 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.
Co-amoxiclav film-coated 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.

Advice/medical education
Antibiotics are used to treat infections caused
by bacteria. They have no effect against
infections caused by viruses.

Rare: may affect up to 1 in 1,000 people

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.

Side effects that may show up in your blood
• low number of cells involved in blood clotting
• low number of white blood cells

Bacteria can become resistant to antibiotics
for many reasons. Using antibiotics carefully
can help to reduce the chance of bacteria
becoming resistant to them.

Not known: frequency cannot be estimated
from the available data
• inflammation of tubes in the kidney
• hyperactivity
• black tongue which looks hairy
• inflammation of the protective membrane
surrounding the brain (aseptic meningitis)

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.

Side effects that may show up in your blood
• increase in some substances (enzymes)
produced by the liver

5. How to store Co-amoxiclav film-coated

1. It is very important that you take the

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.

Keep this medicine out of the sight and reach
of children.
