What Kinds of Insulin Do Diabetic Cats Use?

One of the things that amazed my human when he first was learning about treating me is that feline diabetes is treated almost exactly the same as human diabetes.  There are so many different choices when it comes Insulin Vialto the insulin to use.

You read about Clyde, and how he’s being treated with Humulin. That’s just one of the different types of insulin used to treat cats.

All of them have different benefits and drawbacks.  I personally have been on two different types of insulin since I’ve been diagnosed with feline diabetes.

Initially, I started off with Prozinc.  This is a synthetic analogue of a beef and pork derived insulin, also known as PZI.  Companies stopped making the natural PZI in the 1990s, and it’s now difficult to find.  So Prozinc was developed to replace the natural PZI.

My results with Prozinc were not good.  Maybe it was because both my human and his vet were just starting to get a handle on my diabetes, but it didn’t seem to work too well.  Since my primary vet couldn’t get a handle on what was happening to me, we went to a specialist.

The specialist recommended that we switch to Levemir, which is an ultra slow release insulin that’s a synthetic version of what you humans have.  My human hates to waste things, so he used up the Prozinc before switching.

Another difference between Prozinc and Levemir is the dosing levels.  Prozinc doses are based on 40 units per milliliter.  Levemir dosing levels are based on 100 units per milliliter.

I’ve seen much better results with Levemir.  I’m not sure if it’s because of the drug or if it’s because my human has gotten better at treating my diabetes.

When I was on Prozinc, I saw a spike to a level where the meter just read “HI,” which meant that my glucose level was over 750.  That was at the specialist, and I had already been to see my regular vet that day.  So two vet visits, a drive in the car, and a hot San Diego day may have had a lot to do with this.  But even given this, that was way too high.

Now, though, my human is unhappy when my glucose reading goes even a little over 300.  The vet even called my blood sugars fairly well controlled.

I don’t know if it’s the different insulin, or my human getting better at treating me.  But we are happy either way because my diabetes is under much better control!
