About UltiCare VetRX

UltiCare VetRx Insulin Syringes

Pets are important members of the family, so naturally, you want the very best for them. Optimize care for your pets with diabetes with UltiCare VetRx Insulin Syringes. They help provide comfortable and accurate dosing of insulin to help you better manage your pet’s diabetes. Available in boxes or in the UltiGuard Safe Pack, a dual-purpose system that dispenses new syringes and provides safe disposal for used syringes all in one, so you don’t have to hassle with a separate sharps container.

Choosing the Right Insulin Syringe

Your veterinarian may prescribe U-40 or U-100 insulin for your pet, and it is critical to use the corresponding syringe for proper dosing.

U-40 Insulin Syringes

The “U” refers to units of active insulin, and U-40 insulin has 40 units of insulin per milliliter of liquid. This more soluble type of insulin is designed specifically for cats and dogs, and you must always use a U-40 insulin syringe, which is smaller and has a red cap, to administer it.

U-100 Insulin Syringes

U-100 insulin has 100 units of insulin per liquid milliliter, so it has 2.5 times the insulin as U-40 insulin by volume. If your vet prescribes this type of insulin, it is essential to administer it using U-100 syringes, which are larger and have an orange cap, to ensure proper dosing.

The Quality You Expect

From plunger to tip, UltiCare VetRx insulin syringes are precision engineered to provide superior comfort for your pet.

Human Grade

UltiCare VetRx insulin syringes are human grade, premium quality syringes made for use with U-40 or U-100 insulin.

Superior Comfort

The tri-bevel tip is micro polished and silicone lubricated for easy insertion and effortless glide.

Easy and Accurate Dosing

A clear barrel with bold scale markings and large barrel flanges provides accurate dosing and a good grip for control.

Step-by-Step Guides

UltiCare VetRx offers a suite of diabetes care resources to help you manage your pet’s diabetes with confidence.

Designed With Safety in Mind

The UltiCare VetRx UltiGuard Safe Pack allows you to easily dispense premium quality UltiCare syringes and dispose of them safely once you’re done. Each UltiGuard Safe Pack contains 100 insulin syringes. After using a syringe, simply pop it in the top, then drop and roll it safely out the way. There’s no need to spend more on a separate sharps container with this convenient, affordable solution that helps keep your home and community safe.

An All-In-One Solution

The UltiGuard Safe Pack features an upper and lower chamber. The lower chamber dispenses new insulin syringes, while the upper chamber provides a safe place to discard used ones. After depositing a used syringe in the top, turn the wheel on the side of the container to secure it safely away. Once you’ve used and disposed of all the syringes in the Safe Pack, follow state and local guidelines for proper disposal.

They make premium insulin syringes you can order on their own or as part of the UltiGuard Safe Pack, a convenient all-in-one dispensing and disposal solution that helps keep healthcare providers, pet owners, pets, and communities safe from accidental needle stick injuries.

These are very similar to what I got at my Vet for my Diabetic cat & cost less. They work well for us, are easy to read and Chewy always has top notch customer service. I only wish my Vet still dealt with Chewy vs I have to mail in the script myself now. Which isn’t a huge deal but definitely slows down the process of getting them to me. But, I can see where in the process things are when I check the status of my order.

Perfect Solution

This syringe is exactly the right needle length, dia, and volume for use with a dog with long fur. Human syringes just don't fill the bill.

New customer and satisfied.

We have a recently diagnosed diabetic dog. Chewy had the same needles in stock that our vet started us with. Thanks

Product has changed, and not for the better!

I had ordered two boxes months ago and had no issues with them. This time, however, I noticed a difference right away. The clear end cap was ridged and felt different from the previous smoother end caps. Not really a problem, but when I tried to fill the first syringe with just the 1cc that my cat needs 2x daily, I had a really hard time because the numbers were much smaller than before and the marks were less obvious. It was definitely much harder to gauge where the line was. I will keep using them, but I will also need to use a magnifying glass to be sure I dose her correctly.

Saved $10

This product I've been getting from my Vet at $10 more. Great price and good needles.

Poorly designed

The first batch was fine, but upon receiving the second batch of syringes I realized the cap design had changed. I usually preload 10 syringes at a time. Just as I completed filling the last syringe, I realized that the insulin had been pushed out after inserting the cap. Thereby wasting a lot of very expensive medicine.

Poor quality insulin syringes

Don't waste your money on these terrible syringes. The needle is flimsy and can barely puncture the insulin pen and this also makes it difficult to inject the animal.

Diabetes in cat

Finding out my cat has diabetes was not easy to hear. So it was nice to know a good place to get his supplies quick. It was easy to order and it was quick to get here. The product was exactly what I need to inject his insulin

I relied on Chewy's "frequently bought with" suggestion... that was a mistake. We need to dose adjust (according to TR [tight regulation] protocol at FDMB) with Lantus as low as .25 that's not feasible with 1 IU markings. Stupid me bought 4 boxes. I'd like to return the 3 unopened ones.
