Your Patient Can't Find Their Bowel Prep — And the Colonoscopy Is This Week

You've seen it happen more often than you'd like: a patient calls two days before their scheduled colonoscopy because their pharmacy doesn't have Suprep Bowel Prep Kit in stock. Your front desk is fielding the call, your schedule is full, and the patient is anxious about whether they need to reschedule their screening.

This scenario is increasingly common. While Suprep Bowel Prep Kit (sodium sulfate/potassium sulfate/magnesium sulfate) isn't in a formal FDA-listed shortage, practical pharmacy-level availability remains inconsistent across the country. As providers, we can take proactive steps to minimize these disruptions and keep our patients' colonoscopies on schedule.

Current Availability of Suprep Bowel Prep Kit

Suprep Bowel Prep Kit, manufactured by Braintree Laboratories, is still actively produced and distributed. Both brand-name and FDA-approved generic versions (sodium sulfate/potassium sulfate/magnesium sulfate oral solution) are on the market.

However, pharmacy-level availability varies significantly by region, chain, and timing. Contributing factors include:

• Low par levels: Most pharmacies stock only 1-3 bowel prep kits at a time, given the intermittent demand pattern
• Increased screening volume: The 2021 USPSTF guideline change (screening from age 45) has expanded the patient pool significantly
• Brand-to-generic transition: Some pharmacies carry only the generic, others only the brand; patients may be told the medication is "unavailable" when only one version is out of stock
• Seasonal peaks: March (Colorectal Cancer Awareness Month) and January (new insurance benefits) tend to see higher screening volumes

Why Your Patients Can't Find It

From the patient's perspective, several barriers create the impression of a shortage:

1. Chain pharmacy inventory: Large chains use centralized ordering algorithms that may not prioritize bowel prep kits, especially at locations with lower colonoscopy volume in the surrounding area
2. Prescription specificity: If the prescription specifies brand-name Suprep, a pharmacy with only the generic on hand may report it as unavailable rather than substituting
3. Last-minute fills: Patients often wait to fill the prescription until 1-2 days before their procedure, leaving no time to troubleshoot if stock is low
4. Lack of search tools: Most patients don't know how to efficiently search for medication availability across multiple pharmacies

What Providers Can Do: 5 Actionable Steps

Step 1: Prescribe Early and by Generic Name

The single most impactful change is timing. Send the bowel prep prescription to the pharmacy at the time the colonoscopy is scheduled, not 3-5 days before the procedure. This gives patients and pharmacies days or weeks to fill the prescription, with time to order if needed.

Prescribe by generic name — "sodium sulfate/potassium sulfate/magnesium sulfate oral solution" — unless there's a clinical reason to require the brand. This maximizes the pharmacy's ability to dispense whatever version they have in stock.

Step 2: Direct Patients to Medfinder

Medfinder helps patients (and practices) locate medications in stock at nearby pharmacies. Consider incorporating Medfinder into your colonoscopy scheduling workflow:

• Include the Medfinder URL in your pre-procedure instruction packet
• Train scheduling staff to mention Medfinder as a resource when patients call about prep availability
• Use Medfinder internally when a patient reports a stock issue to quickly identify an alternative pharmacy

Step 3: Build an Alternatives Protocol

Create a simple decision tree for your practice that staff can follow when Suprep isn't available:

1. First choice: Generic Suprep (sodium sulfate/potassium sulfate/magnesium sulfate) — same medication, lower cost ($35-$75 with discount cards)
2. Second choice: Sutab (tablet-based, $75-$150) — especially good for patients who dislike liquid preps
3. Third choice: GoLYTELY generic (PEG-3350, $10-$30) — most affordable and universally available, though higher volume
4. Fourth choice: Clenpiq ($150-$250) or Plenvu ($150-$200) — for patients who need low-volume options and cost is not the primary concern

Empower your nursing staff or medical assistants to initiate the switch protocol when patients call, reducing the turnaround time from days to hours.

Step 4: Partner with Reliable Pharmacies

Identify 2-3 pharmacies in your area that consistently stock bowel prep medications. Independent pharmacies are often particularly reliable partners because:

• They can order medications with faster turnaround from their wholesalers
• They're more willing to maintain par levels based on your practice's referral volume
• You can develop a direct communication channel with the pharmacist

Consider sending prep prescriptions to these preferred pharmacies by default, especially during high-volume screening periods.

Step 5: Educate Patients at the Scheduling Visit

Prevention is the best approach. At the time of scheduling, provide patients with:

• Clear instructions to fill the prep prescription immediately — not the week before the procedure
• A list of pharmacies where the prep is commonly in stock
• Information about the generic option and its equivalency
• The Medfinder URL (medfinder.com) as a backup resource
• Your office callback number for prep-related questions

Alternatives at a Glance

Quick reference for alternative bowel preps when Suprep is unavailable:

• Generic Suprep — Same active ingredients, $35-$75 with discount cards. First-line substitute.
• GoLYTELY (PEG generic) — $10-$30, widely available. 4-liter volume may reduce compliance.
• Sutab — $75-$150, tablet form. Good for patients with liquid intolerance or nausea.
• Clenpiq — $150-$250, ultra-low volume (5.4 oz per dose). Cranberry flavor.
• Plenvu — $150-$200, low-volume PEG prep. Flavored. Brand-only.

Workflow Tips to Reduce Prep-Related Disruptions

• EHR templates: Build bowel prep prescribing into your colonoscopy order set, with generic naming and early send dates as defaults
• Staff scripts: Create a phone script for staff to follow when patients call about prep availability, including the alternatives protocol and Medfinder referral
• Post-scheduling follow-up: Have staff confirm 5-7 days before the procedure that the patient has obtained their prep. This is the last safe window to troubleshoot.
• Patient portal messaging: Send a reminder through your patient portal to fill the prep prescription as soon as possible after scheduling
• Track cancellation data: Monitor how many colonoscopies are cancelled or rescheduled due to prep issues. This data can justify process improvements and pharmacy partnerships.

Final Thoughts

Bowel prep availability shouldn't be the reason a patient misses their colonoscopy screening. By prescribing early, using generic names, maintaining a flexible alternatives protocol, partnering with reliable pharmacies, and equipping patients with tools like Medfinder, your practice can significantly reduce procedure cancellations and keep your screening pipeline moving.
