Before you start treatment

  • Zinplava helps decrease the risk of C-diff (Clostridium difficile infection) from coming back by working with the antibiotic that you are taking to treat your C-diff. It is not an antibiotic and does not replace the antibiotic.

What is Zinplava?

Zinplava is a prescription medicine used to help decrease the risk of C-diff from coming back in people 18 years of age or older who are taking an antibiotic for C-diff and who have a high risk of C-diff coming back.

C-diff is a bacterial infection that can damage your colon and cause stomach pain and severe diarrhea. When people get C-diff, they often take an antibiotic to get rid of the infection. Even when treated by an antibiotic, C-diff can come back within weeks to months. Zinplava helps to decrease the risk of the infection from coming back. It works when given along with the antibiotic that you are taking to treat C-diff.
