However, it’s important to note that more than one concentration of insulin exists, so be sure that the syringe used matches the type of insulin prescribed for your pet. These insulin syringes also come with a sharps container for proper disposal of syringes.

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.

Quality control issues between batches

I've been using this product pretty much since my senior boy was diagnosed with diabetes last year. And up until 2 orders ago, I had no complaints about the product whatsoever. Unfortunately however, with the last order I noticed the plunger on the syringe breaking apart, rendering that syringe unusable. Didn't think anything of it, but then that same issue happened more often with the latest order - I go to fill the syringe, and the little plastic disc on the plunger disintegrates. I do not handle the syringe roughly, and I do not believe this to be somehow Chewy's fault. The product has always arrived sealed in a box with other protective materials, with the syringes in their individual bags in the storage compartment of the container. If anything, this issue appears more down to a quality control problem - have reached out to the manufacturer and they offered to send a replacement and said I should return any unused syringes to them for investigation. Very pleased with that response and will definitely continue to use the product - the convenience of being able to very easily dispose of used syringes is unmatched by any other product that I've come across!

Diabetic Kitty

My cat is newly diabetic & these are the syringes the vet has prescribed her. I specifically chose this version of the U-100s so that I could easily give the box to my vet clinic for safe disposal. Bonus is that the needles are are so thin my cat doesn’t even notice when I’ve given her a shot.

Very good insulin syringes

My dog is a diabetic and these syringes work very well for her. I inject her twice daily while she's eating and she never flinches or makes a fuss.

Syringes - Cat with Diabetes

The syringes purchased through Chewy.com are more compact, sturdy, and has a slightly smaller needle that lends itself to providing an injection of insulin to our cat. The others we've had used were too long. And the added benefit to this purchase is the container in which the syringes were delivered to us can also be used for disposal after use. This is a great concept, thank you UltiCare and Chewy.

Insulin syringes for dogs and cats

These are great because they’re disposable back into the container they come in. I also can buy them for half the price of what the vet was selling them for. I highly recommend this product.

Putting the Spunk back in his steps

My dog Jethro is 9 and needs injections to help repair the damage done from arthritis. I needed syringes right away. Chewy came through in 2 days.... very happy with Chewy! Thank you for coming through Chewy
