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.

About UltiCare VetRx

UltiCare VetRx optimizes care for pets with diabetes. 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. UltiCare VetRx insulin syringes are made specifically for use with either U-100 or U-40 insulin and come in 3/10cc, 1/2cc and 1cc sizes.

They are the most polite people i have ever talked to over the phone. They are so helpful and they actually care about you and your pet. I dont usually leave a review to these things but I just had to let others know about my wonderful experience with chewy. My dear daisy has diabetes and they have just been wonderful through all this. Thank you to all the people who have helped me with my orders of her medicine. If I could give you a higher rating I would

Ease of ordering

When many places around here at pharmacies cannot get the syringes and are on backorder, I can always count on Chewy!

I have had 2 rescue that had diabetes. The cost is really to high in the vet's office for med's. Sadly, Speedy past away for I used them. I know they are good needles. I was paying double at the vet's. I ended up giving them to a rescue. Thanks

No Issues

Haven't had any issues with these syringes. Have bought for over a year. Cheaper here than at the let's office.

How easy to order diabetic supplies

Everything went very well with my Duncan's first order of diabetic supplies. His vet signed the script and the insulin and syringes were delivered quite promptly

Everything went very well with my Duncan's first order of diabetic supplies. His vet signed the script and the insulin and syringes were delivered quite promptly. Techs are very easy to talk to even in the middle of the night. Quite happy, Chewy is so very easy to work with and the price is much better than the vet's.

Same as Dr.

My fat cat has developed diabetes and vet charges a little more for the same needles. No problem having Chewy obtain RX for me.

Our vet gave us a bag of these at the clinic so we decided to get more on chewy.

These are pretty great. They have small needles so the cat can't feel a thing when we inject her with her insulin every feeding time. What is also great, you can

These are pretty great. They have small needles so the cat can't feel a thing when we inject her with her insulin every feeding time. What is also great, you can use the same syringe a few times before having to throw them away. Its a great money saver. I definitely recommend this product!

Ease of autoship

I purchase this at vets. I saved over $16 by autoship with chewy. Having it come to my front door is easier than going to my vets when needed
