About This Item


Insulin Syringes/Needles U-40 29 Gauge x 0.5-in are prescribed by your vet for the injection of U-40 (40 units per ml) insulin in your diabetic pet. 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 sterile, single-use, individually packaged syringes feature an attached needle, polypropylene barrel and plunger rod, latex-free plunger tip, and graduated barrel markings.

Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.

Outstanding value for a necessary product

We have a diabetic dog who requires insulin injections twice a day so we go through a lot of syringes. My vet charges $45 for 100. This brand from Chewy is as good as the ones I get from the vet and at an extremely fair price (even more so with auto delivery). You will need to get your vet’s authorization but if your savings are as good as mine you would be foolish not to.

Syringe Review

Unfortunately my cat had to be put down, I received the insulin and syringes a little later than expected due to Vet approval etc, so I have unusable materials left

So happy you have these!

I swear by Chewy, I have two diabetic kitties and couldn't be happier with not only the insulin being delivered to my door by Chewy but now the syringes.

Insulin syringes

These syringes do not have enough lines on them for measuring small amounts of insulin. I could not use these for my dog. He only needs a small amount

Reasonably priced quality product.

Considering the price, compared to name-brand pharmaceutical syringes, this product does its job, and the price is quite fair.

Stay away from these

these are the worst I have ever used and overpriced. I usually get my needles from adw because they have better deals on the needles. I love chewy but if I can save a little money on diabetic supplies that is what I do. Plus I ended up throwing a lot of these in the bag with the used ones to take to my vet for disposal.

Insulin Syringes

Once I ordered them Chewy was right in top of getting the RX from the vet and sent them right out. Exact ones the vet gave us..
