Lantus

Help control your cat’s diabetes mellitus with Lantus-brand insulin glargine. This injectable medication helps regulate blood sugar in cats. Normalized blood sugar can help your feline friend feel better day-to-day. 

  • Regulates blood sugar levels
  • Daily dosing
  • Formulated for subcutaneous injection

Lantus helps treat diabetes in cats by normalizing the glucose level in the blood. When your cat has a normal level of glucose in the blood the body works as it should and your cat may have fewer diabetic symptoms. Lantus is insulin glargine, a long-acting form of insulin formulated for injection underneath the skin.

  • Q:

    When using the Solo Star pen, do I have to prime it every time?
    Asked on 5/6/2015 by mccartanann from Holliston, MA

    1 answer

    • A:

      Yes, the manufacturer recommends that you dial a test dose of 2 units before each dose. Hold the pen with the needle pointing up and lightly tap the insulin reservoir so any air bubbles will rise to the top. This will help make the dose more accurate. Next, press in the injection button all the way to remove 2 units from the pen. If no insulin comes out, repeat this process 2 more times.

  • Q:

    you state that you can't draw the insulin from the pen with a syringe. That is exactly what I've been doing. I don't think my pen has a needle and I don't use the counter. The vet provided me with the Lantus pen and syringes. is your pen different?
    Asked on 3/7/2015 by milo from Sioux Falls, SD, United States

    1 answer

    • A:

      Milo,

      The Lantus SoloStar pen supplied to you by your veterinarian is the same Lantus SoloStar pen that VetRxDirect dispenses to our patients. Lantus SoloStar is human use prescription insulin medication used for the management of diabetes. In humans, the insulin contained in the Lantus SoloStar pen is administered with a needle that is screwed onto the end of the pen. Lantus is available in either a multi-use vial or in the SoloStar pen. As animals usually require less insulin in the management of their diabetes than humans do, it is common practice to utilize the Lantus SoloStar pen and withdraw the insulin from the pen. This is done to be cost effective and decrease the amount of unused insulin remaining at the end of each month.

      Thank you,
      VetRxDirect

My cat uses insulin twice daily. I recently did more extensive research and confirmed that cats tolerate Lantus better than other insulins (cats have a faster metabolism so most insulin doesn't last as long and causes spiky glucose curves). Lantus lasts about 12 hours in a cat. The pen form is easy to draw from and keeps the insulin lasting much longer than the vial due to the lack of air, which denatures the proteins and spoils the insulin. VetRx has a great deal on this item, allowing a single pen purchase with great packaging for protection and sustained cool temperature and overnight shipping. They also have EXCELLENT customer service. They have found a new long-term customer. I love this kitty dearly and with this she is healthy, happy, and lives a normal life. (ok, except for getting pampered frequently.) :)

I purchased this insulin for my cat a month ago and it just isn't working for my cat and I am giving him injections twice daily with no good results. He is still urinating and drinking constantly and losing weight. My vet said that it worked for him when he was in for evaluation but it is just not working for me even with upping the dosage. I will have to try another type of insulin for my cat.

    Comments about sanofi aventis Lantus (insulin glargine injection):

    I use the lantus pen twice per day for kitty. Can be refrigerated for longer use after seal being open pass the expiration date however, different opinions between pharmacy tech. Please research yourself. I have used the pen two weeks pass the expired date and kitty is fine. Some cats may differ. After being refrigerated need to set out to room temperature before use. Also can be used with the other syringe. I also use the needle more than once without any infections occurring. Not recommended by instructions. Kitty must be very clean and I have not had any problems.

                                            Comments about sanofi aventis Lantus (insulin glargine injection):

                                            Monster was diagnosed with diabetes 2 years ago and has been only on Lantus. Because it is so high I was trying to find it in the epi pen which while it doesn't last as long as the vile retains it strength better. He is doing great, looks good eats only MD which is a prescription cat food and has lots of energy. Vet RX is the only place I can find the Lantus in a singe epi pen for sale. Because he takes 3u twice daily it last me about 42 days. By the way the name is because he is truly a monster, loves people hates other animals. Has his own room with a friend with large bed, and lots of toys, he plays outside only by himself some but I always watch him.
