Clinical features

• Within 2 days of taking antibiotic (can start p to 4 to 6 weeks after usage)
• Persists 2 weeks (up to 6) after ceasing antibiotic
• Augmentin duo forte is the common culprit 

Treatment

• Metronidazole 400 mg tds for 10 days

I have seen multiple C. Diff colitis as a registrar last year. Most of the time secondary to inappropriate antibiotic prescription. For some reasons, some GPs like to prescribe augmentin duo forte as the first line antibiotic. If we follow the antibiotic guideline, there are not many conditions which requires augmenting duo forte. Ironically, the cases I saw they didn't even require antibiotic at the first place. 

** Reminder to myself: prescribe antibiotic according to the antibiotic guideline **
