Vowst for Recurrent C. diff: Prevention Is Not Treatment of Active Infection
Bloating & DigestionArticleClarify the purpose of a clinician-proposed prescription and the plan for current symptoms.
In this article
Seek urgent medical advice for diarrhea while taking or after recently taking antibiotics, bloody diarrhea or rectal bleeding, or diarrhea lasting over seven days. Do not wait for a prescription discussion. These symptoms need assessment; they do not establish C. diff themselves.1
What the prescription is for
FDA2 patient information describes Vowst as a prescription medicine for adults aged 18 and older to prevent C. diff from returning after antibiotic treatment has been completed. It is not intended to treat active C. diff infection.2
Ask about both parts of care
Try: “What is treating my current infection, and what is intended to prevent another episode? How does this prescription fit my plan?”21
Tell the prescriber about your conditions, medicines, pregnancy plans or breastfeeding. Have the team explain your individual instructions before taking it.2
Return to a doctor if symptoms worsen, you feel very unwell after starting treatment, or symptoms come back. Do not assume a prevention plan explains new diarrhea.1
