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.

If you forget to give Augmentin

dose to make up for a forgotten dose.
If your child stops taking Augmentin
Keep giving your child Augmentin until the treatment is finished, even if they feel better. Your child
needs every dose to help fight the infection. If some bacteria survive they can cause the infection to

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

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
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.


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.
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.
You should not take antibiotics that have been prescribed for other people even if they had
an infection that was similar to yours.
You should not give antibiotics that were prescribed for you to other people.
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.
