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
substance (clavulanic acid) stops this from happening.
Co-Amoxiclav is used in adults and children to treat the
following infections:
• sinus infections
• urinary tract infections
• skin infections
• dental infections.

- if you are allergic (hypersensitive) to amoxicillin,
clavulanic acid, penicillin, or any of the other ingredients
of Co-Amoxiclav (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 this medicine if any of the above applies to you.
