1. what zinplava is and what it is used for

ZINPLAVA contains the active substance bezlotoxumab.

ZINPLAVA is a medicine that is given together with an antibiotic to prevent Clostridium difficile infection (CDI) from coming back in patients 18 years of age or older who have a high risk of CDI coming back.

How ZINPLAVA works

• When people get CDI, they are usually given an antibiotic to get rid of the infection, but CDI can often come back within weeks or months.
• The bacteria responsible for CDI produce a toxin that can inflame and damage your colon,

causing stomach pain and severe diarrhoea. ZINPLAVA acts by attaching to the toxin and blocking it, thereby preventing the symptoms of CDI from coming back.

2. what you need to know before you are given zinplava

Talk to your doctor before you are given ZINPLAVA.

You should not be given ZINPLAVA if:

• you are allergic to bezlotoxumab or any of the other ingredients of this medicine (listed in

section 6).

Warnings and precautions

ZINPLAVA is not a treatment for CDI. ZINPLAVA has no effect on the CDI you have now.

ZINPLAVA is given with the antibiotic therapy you are taking for CDI.

Children and adolescents

ZINPLAVA should not be used in children and adolescents below 18 years of age.
