Having trouble finding Plenvu for your colonoscopy prep? Learn why Plenvu can be hard to find in 2026 and what you can do to get it filled quickly.
You have your colonoscopy scheduled, your doctor handed you a prescription for Plenvu, and now the pharmacy is telling you they don't have it in stock. Sound familiar? You're not alone.
Plenvu is one of the most popular low-volume colonoscopy prep solutions on the market, and that popularity — combined with supply chain challenges — can make it surprisingly difficult to find at your local pharmacy. In this article, we'll explain what Plenvu is, why it's sometimes hard to get, and exactly what you can do to fill your prescription before your procedure date.
Plenvu is a prescription bowel prep medication made by Salix Pharmaceuticals (a Bausch Health company). Its full generic name is polyethylene glycol 3350, sodium ascorbate, sodium sulfate, ascorbic acid, sodium chloride, and potassium chloride for oral solution.
It's used by adults to clean the colon before a colonoscopy. What makes Plenvu different from older preps like GoLYTELY is the volume — Plenvu is the first and only 1-liter PEG-based prep. That means you drink significantly less liquid, which most patients find much easier to tolerate.
The prep comes as a kit with three pouches: one for Dose 1 (mango-flavored) and two for Dose 2 (fruit punch-flavored). You mix each dose with 16 ounces of water and drink additional clear liquids alongside each dose.
There are several reasons your pharmacy might not have Plenvu on the shelf when you need it:
Colonoscopy screening rates have been increasing across the United States, especially as guidelines now recommend screening starting at age 45. As more people get colonoscopies, demand for more tolerable preps like Plenvu has surged. Doctors and patients alike prefer low-volume options, creating consistent high demand.
Plenvu is a brand-name medication with patent protection estimated through September 2033. Without a generic alternative, there's only one manufacturer producing this specific product. That single-source supply can lead to tighter availability, especially during peak periods.
Many pharmacies — particularly large chain pharmacies — manage inventory through automated systems that may not keep specialty or less-frequently-dispensed items in stock at all times. Plenvu is used as a one-time prep before a procedure, so pharmacies may not keep large quantities on hand compared to daily-use medications.
The broader pharmaceutical supply chain has experienced ongoing disruptions since 2020. While Plenvu has not been listed on the FDA's formal drug shortage list, intermittent supply tightness at the distributor or pharmacy level can still make it difficult to find at any given location.
If you're struggling to find Plenvu, here are some practical steps:
Medfinder lets you search for Plenvu availability at pharmacies near you in real time. Instead of calling pharmacy after pharmacy, you can quickly see which locations have it in stock.
Independent pharmacies often have more flexible ordering and may be able to get Plenvu within 24 to 48 hours. They may also be more willing to call their distributor and check on your behalf.
Many gastroenterology offices have relationships with specific pharmacies or may even stock bowel preps in-office. Your doctor's office may also be able to provide samples or direct you to a pharmacy they know carries it.
As soon as you receive your Plenvu prescription, start looking for it. Don't wait until the day before your procedure. Give yourself at least a week's lead time so the pharmacy can order it if needed.
If you absolutely cannot find Plenvu, talk to your doctor about alternative colonoscopy preps like Suprep, Sutab, or Clenpiq. These are also low-volume options that may be easier to find.
The cash price for Plenvu typically ranges from $150 to $210 per kit without insurance. With commercial insurance, your copay may be significantly lower — and the Plenvu Co-Pay Savings Program can bring your cost down to as little as $0 for eligible commercially insured patients.
Finding Plenvu shouldn't be harder than the colonoscopy itself. The good news is that with a little planning and the right tools, most patients can get their Plenvu prescription filled without too much hassle. Start early, use Medfinder to check availability, and don't hesitate to explore independent pharmacies or ask your doctor for help.
