About This Item


VetOne 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. U-40 syringes are the syringe size that is recommended to use with ProZinc insulin. 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.

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

Diabetic syringes

These were to replace the syringes that I normally use that have been out of stock. Not to my satisfaction.

Too big and too small

The 40 size leaves the graduation lines too close together making it harder to judge the 1.5 dose. You used to sell 30 size which was better and 20 size would be better still.

I don’t usually write reviews on pet items but we got these syringes and they seem to be dosed and accurately. We compare the dosing with similar syringes that we’ve been getting at Walgreens for a couple years and found that the quantity when compared did not match up. Five units on a regular 0.5 mL 50 unit 31 gauge syringe from CVS was much less when compared to “five units“ on these syringes. I would advise anyone buying the syringes to medicate their animals to verify the accuracy of the dosing with the specifics syringe through their veterinarian. Like I said, comparing five units from each of the above syringes was grossly abnormal. Just use caution. No one wants Fluffy to die from an insulin overdose

Best syringe

These ARE the best and what Vets use in their practice. The plunger slides smoothly and tight so you can get the right cc without reloading, with very, very little air bubbles to deal with. I bought a cheaper one here and they were horrible! I returned them and got these. I can use one of these for several applications.

Not even close to being the right ones. They sent ones that aren't right for my little Lucky

Vetone Syringes U-40

Syringes are same as I purchase at my vet. The price is the same. I would suggest Chewy offer a box of 100 at a lesser price than the 10 unit price.

Flimsy and unusable syringes

These syringes are so poorly made that they usually bend and break just trying to insert into the vial. Do not order these.
