A practical guide for providers on helping patients locate Clenpiq for colonoscopy prep, with 5 actionable steps, alternatives, and workflow tips.
You prescribed Clenpiq because it's a well-tolerated, low-volume bowel prep with strong patient compliance. Now your patient is calling back to say the pharmacy doesn't have it. This scenario is playing out in gastroenterology practices nationwide — and it doesn't have to result in a delayed colonoscopy.
This guide provides a practical framework for helping your patients find Clenpiq, along with workflow tips to prevent this problem from recurring.
Clenpiq is manufactured exclusively by Ferring Pharmaceuticals and has no FDA-approved generic. While the drug is not on the FDA Drug Shortage list, it is a single-source brand product that many pharmacies do not routinely stock. This creates a disconnect between prescribing intent and patient access.
The core issue is pharmacy-level inventory management. Most retail pharmacies, particularly chains, order Clenpiq on demand rather than maintaining standing stock. If the wholesaler doesn't have it ready for next-day delivery, the patient faces a delay.

Understanding the failure points helps you intervene more effectively:
Write the Clenpiq prescription at least 7–14 days before the procedure date. This is the single most effective intervention. It gives the pharmacy time to order the medication and gives the patient time to find an alternative pharmacy if the first one can't fill it.
Include a note with the prescription: "Please fill immediately. Contact our office at [phone] if this medication is unavailable."
Before the patient leaves your office or during the scheduling call, use Medfinder for Providers to check which pharmacies near the patient have Clenpiq in stock. This takes seconds and can prevent the entire problem.
If the patient's preferred pharmacy doesn't have it, you can direct the prescription to one that does — before the patient ever encounters a stock-out.
Develop a standardized backup plan for your practice. When Clenpiq is unavailable, your staff should know exactly which alternative to prescribe and how to communicate the switch to the patient. A sample protocol:
Print prep instructions for each option so you can hand them to the patient immediately upon switching.
Make sure schedulers, nurses, and medical assistants understand:
Include a brief note in your pre-procedure instructions:
"We've prescribed Clenpiq for your bowel preparation. Please fill this prescription as soon as possible — do not wait until the day before your colonoscopy. If your pharmacy does not have Clenpiq in stock, please contact our office immediately at [phone] and we will provide an alternative."
This sets expectations and gives the patient a clear action plan.
When switching from Clenpiq, these are the most commonly used alternatives:
Note: Clenpiq, Suprep, and Sutab are all contraindicated in patients with severe renal impairment (CrCl <30 mL/min). GoLYTELY is generally preferred in this population.
Clenpiq availability challenges are a predictable consequence of single-source manufacturing and pharmacy stocking patterns. As a provider, you have more power to prevent delayed colonoscopies than you might think — and most of it comes down to prescribing early, checking stock proactively, and having a backup plan ready.
The tools exist to make this simple. Use Medfinder for Providers to check real-time stock, keep alternative prep protocols standardized, and educate your team and patients about what to do when Clenpiq isn't on the shelf.
