Insulin Syringes/Needles U-40 29 Gauge x 0.5-in are used for the injection of U-40 (40 units per ml) insulin in pets with diabetes. 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.


Syringes are primarily used to administer insulin to dogs and cats.


Used sharps should be immediately placed in a sharps disposal container. FDA-cleared sharps containers are generally available through pharmacies, medical supply companies, health care providers and online. These containers are made of puncture-resistant plastic with leak-resistant sides and bottom. They also have a tight fitting, puncture-resistant lid. If an FDA-cleared container is not available a heavy-duty plastic household container, such as a laundry detergent container can be used as an alternative.

  • Does The Job

    By on

    Been using these syringes for over 1 year now for my diabetic cat. Very easy to use and my cat doesn't seem to mind the injection. Also like the plastic container that it comes in which makes disposal of the syringes very easy. One thing to remember is that you need to push the plunger down initially when you first take the syringe out which eliminates the air.

  • Good product, wish we didn't need it

    By on

    the diagnosis of diabetes was unwelcome. Finding good products to deal with the necessary injections is helpful. This is a great product and the sharps container is most welcome as dealing with disposal is just an additional hassle on top of dealing with a sick loved one.

  • Neat package

    By on

    This is a handy package with syringes stored underneath the disposal container. Keeps everything together. Needles are sharp. Bought the .3cc syringe so markings are easier to read. Only problem is the plunger tip can pull off. If you push the plunger all the way in the tip will re-engage so you don't waste a syringe. It would be great if there was a way you could return the used syringes for disposal. Only wish the price was less.

  • Good Product At A Good Price

    By on

    100 syringes and a container to put the used syringes in when you are done with them. I thought it was a good price. My dog is diabetic and I have to give her shots twice a day and this is quite a savings because I did shop around and I couldn't find a better price anywhere.

  • Great size for smaller doses

    By on

    After trying the 1cc and 0.5cc size U-40 needles for my cat's insulin injections, I found this 0.3cc size to be perfect. Each cc is marked, making the dosing very simple to follow. I like the disposal container as well. The needles come out in 10-packs from the bottom of the container while the used syringes are safely deposited through the top of the container, and the entire container, once all the syringes are used, can be taken to your vet for disposal.

  • Well designed

    By on

    These are superior to other brands for one important feature. The cc markers are easy to read to draw the proper amount. Instead of 5, 10, 15, etc. with hashmarks separating those numbers. This product has each number marked; 1, 2, 3, 4, 5, etc. Huge and appreciated!

  • Needles weren't as sharp as I normally but from my vet clinic

    By on

    The needles appeared to be dull in sharpness and a little tough to pull back the insulin in. I don't know if I got a bad batch or what, I am always happy with Chewy's products.

  • Positive product

    By on

    Take a negative and turn it into a positive. My dog developed diabetes and my vet recommended this product. It transfers the medicine well and the dog has no idea he is getting a shot.

  • Great Price, Easy Process

    By on

    One of our cats was recently diagnosed with diabetes requiring insulin shots twice a day. The savings on both the insulin and the needles was almost $20.00 as compared to buying these products through the Vet, so I was delighted! The process of getting the needed script from our Vet plus a very speedy delivery made the whole purchase very satisfactory.

  • Perfect for Administering Vetsulin

    By on

    I administer two doses of insulin a day with these syringes to my diabetic cat. The syringe is easy to read and easy to use. I have tried other syringes, but none come close to the quality of these.
