FOR PATIENTS
The part you have been dreading? We Fixed it.
ZeraFlow replaces days of at-home laxative prep with a comfortable, 30-minute in-clinic experience. Nothing to drink the night before. Nothing to manage at home. Just show up.

Patient preference over traditional prep
ZeraFlow was built specifically for this problem.
Three steps. That is all.
-
The night before
Take three mild tablets. No large volumes of liquid. No major dietary restrictions. A light dinner as normal.
-
Morning of your colonoscopy
Arrive at your clinic at your scheduled time. No different from any other morning appointment. Your care team takes it from here.
-
Your ZeraFlow prep (30 min)
A registered nurse guides you through a gentle warm-water cleanse. Most patients describe it as surprisingly easy. You will be fully prepared before the colonoscopy begins.
ZeraFlow is performed in a private room at your clinic with a single registered nurse. It is not a group experience. It is not embarrassing. The process is gentle, supervised, and over in 30 minutes — after which you go straight into your colonoscopy. Patients consistently describe it as far more dignified than spending a day and night alone managing harsh laxatives at home.
What about privacy?
