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.
Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.
The needle is well marked, however have had numerous needles that would not penetrate the rubber on the insulin bottle. And if you're lucky to get the needle to penetrate the bottle, the needle immediately bends at a 90 degree angle when inserting into our cat. Thus the insulin goes onto the cat's hair instead of into the cat. Wasted that insulin..... Need to start all over. And at almost $70 for a bottle of insulin, every drop of insulin is precious. HATE the wasted insulin!!!!! There are 2 humans administering this. And this has happened to both of us. PLEASE get the Monoject syringes back in stock!!!!
I had to research to find another syringe that worked well with Prozinc since Monoject syringes were out of stock. Charlie, our diabetic cat tolerated the Monoject ones so I was hesitant to try something new. I was super surprised that actually they are very comparable if not better! I ALWAYS prime the syringe & we’ve had no problems! Just make sure you pick the right size for your insulin requirements but for Prozinc U40 29g needles this was purrfect for us!
Our kitty was recently diagnosed with diabetes. The initial box of syringes that I purchased from the vet ran out, so I bought these. They work fine except that the plunger on the syringe sticks when you initially pull it to fill the syringe with insulin. Annoying, but not the end of the world.
My cat is diabetic and, as those who have diabetic pets know, the cost for their care is expensive. These needles are relatively inexpensive for a quantity of 100. I'm a little on the fence about the packaging. The needles are bagged in groups of ten and the plunger has a cap which seems unnecessary. However, I can see if you were traveling with your animal, the bags would be handy, even though they aren't resealable. I've been using them for a month with no issues with the plunger and the needle caps slide on easily for safety and disposing.
This is the brand of needles that my vet recommended, but I can get for less at Chewy. I also sometimes get the version that comes with the sharps box, but I find you can fit more needles in the box than come with it, so I buy the separate needles. The sharps box only adds like $10 bucks, but you can also use a heavy duty plastic bottle, like a detergent bottle, and mark it sharps. I can stop by my local medical center and drop them off any time the lab is open. So, considering how not convenient it is to have a diabetic kitty, this is about as easy as it can be made, I think.
These insulin syringes are much lower quality than the Monoject brand chewy used to stock. Needle is dull after just drawing insulin from bottle so harder to inject the cat. Bring back monoject !!!
1 OUT OF 3 BEND WHEN INSERTING INTO MY CATS NECK SCRUFF, HAVE TO TAKE EXTRA CARE AS WHEN I FIRST NOTICED HE DIDN'T GET HIS MEDICATION AND BLOOD SUGAR WENT OUT OF CONTROL RESULTED IN ANOTHER TRIP TO VET, COULD HAVE KILLED HIM.
This is a very good product but it’s to expensive for my budget would like to go back to my regular insulin needles that I had before these they do great and are less expensive. Sorry
The syringes appear to be just as good as the other brand that I was buying. But they have been out of stock. The only thing I dislike is they are not packaged individually to be sterile. They are 10 in a pack so when you open the pack all of them are open to germs.
I used it for 10 days thinking maybe I was just being difficult, but both my husband and I noticed that the U-40, 1/2 inch, 3/10 cc (purple box) without the half unit marking were noticeably different from the ones with the half-unit markings, which we’d used exclusively for months since Bro became diabetic. The ones without the half unit markings left a bubble in 3 out of 4 times I drew the insulin, and made my cat complain when poked. He never noticed or cared with the other ones! These syringes suck.
