Prevention of recurrent Clostridioides difficile (C. difficile) infection in adults who have previously experienced recurrent episodes of this bacterial infection, typically after antibiotic treatment.
Vowst contains spores from Firmicutes bacteria that are naturally found in a healthy gut microbiome. These spores help restore the balance of beneficial intestinal bacteria, which can outcompete C. difficile bacteria and reduce the risk of infection recurrence.
Vowst is taken orally as capsules over a 3-day period. It should be used with appropriate caution in patients with compromised immune systems. Common side effects may include abdominal bloating, fatigue, constipation, chills, and diarrhea. Patients should inform their healthcare provider about all current medications before starting treatment.
