Conventional versus extended-pulsed fidaxomicin dosing in patients at high risk of recurrence of Clostridioides difficile infection: a propensity score analysis.

Although the recurrence rate with FEPD was numerically lower than that observed with FCD, we have not been able to show that the recurrence rate of CDI is different depending on the dosage regimen of fidaxomicin. Clinical trials or large observational studies comparing the two dosing regimens of fidaxomicin are needed.
