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.

  • Not a fan of these syringes

    By on

    I much prefer standard U-40 syringes without all of the waste of this huge container and the additional packaging and plunger cap. The increase in cost to cover all of this is not necessary. I am very happy with Chewy in general but wish there were other options for people that have availability of disposal without this. thanks

  • Reasonable price quality syringes

    By on

    I prayed I would never need to use these but I have a cat recently diagnosed with diabetes. These syringes are of good quality and I love the disposal box too. A little early for any other reviews at this time but should I have a different opinion later then I will update.

    By on

    It was great to be able to purchase this item on Chewy. My dog just got diabetes and to find products like this one, in the size I needed for her was just great. With quality and lower cost than my veterinarian, this product I would highly recommend!!

  • Ordered correctly/Product incorrect

    By on

    We ordered the exact Syringes (specifications) that we were getting from the vet, however your product only allows for 12 units when our old vet provided product allowed up to 20 units. Our dog has to take 14 units twice per day so your syringes are useless to us. See attached picture. Sorry when I click on option to add picture it will not allow me to add so send me a separate email and I will reply with picture attached.

  • The needles work just fine.

    By on Top 500 Contributor

    The problem is getting the orange cover off the needle. I purchased this exact needle from the vet and easily separated the cover from the needle. Not so with these, at least this particular batch. I finally used the side of a knife to get the thing to release.

    Great price too. Shipping was lightening fast. I ordered on a Friday night (with a new prescription that needed to be confirmed) and my order arrived Monday (on a holiday to boot). I won't go anywhere else.

  • Won't buy again

    It's hard to keep up with how many syringes you have left while using this Sharps Container. I was using a coffee can to put my used syringes in and keeping them until I go to my City's drop off.

  • Great Packageing

    By on

    These are great syringes for my diabetic cat. The greater thing about this brand is that they package the syringes with their own sharps disposal container! Very easy! Very helpful!

  • 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.

  • 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!
