You can buy certain urinary catheters without a prescription from online medical supply retailers and, in limited cases, from major retailers like Walmart. However, the answer depends on the type of catheter you need. Indwelling (Foley) catheters are classified by the FDA as prescription devices, meaning federal law restricts their sale to orders placed by or on behalf of a physician. Intermittent catheters and external catheters have more flexible purchasing options.
Which Catheters Require a Prescription
Foley catheters, the type that stay inside the bladder with an inflated balloon, carry FDA-required labeling stating: “Federal law restricts this device to sale by or on the order of a physician.” This means no legitimate U.S. retailer should sell you one without documentation from your doctor. The restriction exists because Foley catheters carry significant risks when placed incorrectly, including urethral trauma, false passages through the urethral wall, bladder rupture, and serious bloodstream infections.
Intermittent catheters, the kind you insert briefly to drain the bladder and then remove, are more widely available without a prescription. Some retailers and online suppliers sell them directly to consumers with no documentation required, though others still ask for a prescription depending on their own policies.
Online Retailers
Online medical supply stores are the most common way people purchase catheters directly. Aeroflow Urology, one of the larger catheter suppliers, sells both with and without a prescription. Their catalog lists over 100 products requiring a prescription alongside roughly 37 that don’t, so you’ll need to filter by what’s available for direct checkout. You can create an account and order for home delivery, and shipments typically arrive in discreet packaging.
Walmart’s website lists around 10 urinary catheter products available for shipping, pickup, or delivery. Other online medical supply companies like 180 Medical, CompactCath, and Medical Monks also sell intermittent catheters directly to consumers. Availability and prescription requirements vary by seller, so check individual product listings before assuming you can add to cart and check out.
If you have insurance, many of these suppliers also handle the coverage process for you. Aeroflow, for example, offers a qualification form where a specialist contacts you, sends free samples, and helps you find the right product while billing your insurance.
Brick-and-Mortar Stores
Walk-in options are limited. Most major pharmacy chains like CVS and Walgreens do not routinely stock urinary catheters on shelves the way they stock blood pressure cuffs or glucose monitors. You may find external collection devices (condom-style catheters for men) at some locations, but intermittent and indwelling catheters are rarely available for same-day, in-store purchase.
Some Walmart locations may carry basic catheter supplies or can facilitate a store pickup for online orders. Independent medical supply stores in your area are another option worth calling, as they often stock a wider range of urological products than chain pharmacies.
Buying Catheters in Canada and the UK
In Canada, intermittent catheters are available for purchase online without a prescription through retailers like CanMedDirect, which stocks over 200 catheter options from major manufacturers. In the UK, most people who need regular catheterization receive supplies through the NHS, but private purchase through online medical suppliers is also possible. Prescription requirements in both countries are generally less restrictive for intermittent catheters than for indwelling ones, similar to the U.S.
What Medicare Covers
If you’re on Medicare, catheter supplies fall under the prosthetic benefit (Part B). Coverage requires documented medical necessity in your records. For intermittent catheterization, Medicare covers one catheter plus a lubricant packet per use, or a sterile catheter kit if you meet specific criteria like being immunosuppressed, living in a nursing facility, or having a history of recurrent urinary tract infections. For indwelling catheters, Medicare covers one per month for routine maintenance, plus additional replacements when there’s a documented reason like accidental removal, malfunction, or obstruction.
Going through a catheter supply company that accepts Medicare assignment often means lower out-of-pocket costs than buying retail. Many suppliers handle the paperwork and ship monthly supplies directly to your home.
Why Proper Sizing and Training Matter
Buying a catheter is straightforward compared to using one safely. Catheters come in different French sizes (a measurement of diameter), lengths, and tip styles. Using the wrong size or inserting incorrectly can cause real harm. In men, the catheter can curl or kink inside the urethra, butt up against the prostate, or push through the urethral lining to create a false passage. These complications cause pain, bleeding, and can lead to infections that spread to the bloodstream.
People who self-catheterize regularly, such as those with spinal cord injuries or neurogenic bladder conditions, are at higher risk for creating false passages over time. Even in hospital settings with trained nurses, catheter misplacement causes injuries. If you’re new to catheterization, getting hands-on instruction from a nurse or urologist before purchasing supplies on your own is the single most important step you can take. They’ll also help you determine the correct catheter size and type for your anatomy, which makes self-purchasing much simpler going forward.
For people already experienced with self-catheterization who simply need a reliable supply source, online ordering through a medical supply company offers the best combination of product selection, competitive pricing, and the convenience of recurring home delivery.
