1. What Augmentin is and what it is used for
What Augmentin is
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

• middle ear and sinus infections

Do not take Augmentin:
• if you are allergic (hypersensitive) to amoxicillin, clavulanic acid,
penicillin or any of the other ingredients of Augmentin (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

causing your infection. Depending on the results, you may be given a
