They are available in 1/2cc or 3/10cc 30 gauge syringes with a 5/16" lubricated needle. UltiCare U-100 syringes require a prescription from your veterinarian if you reside in Connecticut, Delaware, New Hampshire, New Jersey, Oklahoma, Florida (Broward and Dade counties) or New York.

UltiCare U-100 syringes are an ideal syringe for use with Humulin N & Novolin N insulin. When used according to your veterinarian's instructions, these syringes play a key role in helping to manage your pet's blood glucose levels.

  • U-100 syringes contain a silicone coated needle to help ensure ideal comfort.
  • Do not sterilize or reuse syringe.

Keep the vial upside down, with the syringe needle pointing upwards to release the insulin back into the bottle if any air enters the syringe.

Customer Reviews
UltiCare U-100 Syringes is rated 3.0 out of 5 by 3.
Rated 2 out of 5 by from plunger sticks These are so much harder to depress than the ones from my vet. Not sure the savings is worth it. Unfortunately since I just got 100 of them I can't afford to just toss them out.

Rated 5 out of 5 by from Insulin Syringes For the price these are great. I have 2 diabetic cats so use 4 of these every day. I liked the ones I got from the vet better, but for the price these work just fine and cost a lot less. I do have to be careful filling them and make darn sure to get all the air out, but they do work as advertised and are just fine. Good product for the price.

Rated 2 out of 5 by from OK, but not as good as Nipro The aren't as smooth, and you have to remember to fully depress the plunger before drawing insulin into the syringe. Otherwise you end up with additional air in the syringe that is difficult to remove. When I purchased these syringes, the Nipro were pictured, but I received the UltiCare and now it is the pictured product. "PetMeds" branded. But I wouldn't put my brand name on them...

How do I disposed of used syringes?

Do you provide a returnable case that I can dispose syringes? Thanks.
Asked by: Brian
Thank you for your question. This product does not come with a sharps container so you would need to purchase one locally.

prozinc kit

how do you dispos the used neddels
Asked by: dick
I use an old Gatorade bottle, mark it "SHARPS" and when it is full, discard as normal in my regular trash. This way, they are contained, marked, and safe from accidental touch. A friend of mine told me this would be a good/legal way to dispose of the old needles, and I've been using it for over 6 months now.

Our dog has just been diagnosed with type 1 diabetes and. Needs insulin shots. But Custard is a shelter dog and we feel would bite if injected

Any other way we can take care of her without the injections ?
Asked by: Ray
Type 1 diabetes is a form of diabetes mellitis that results in a lack of insulin. Therefor the usual treatment is to give insulin. Speak to your veterinarian regarding your options in trating your dog.
