? Has anyone here switched from Prozinc ?

[Alexandra M]

My cat is currently on 1.25 u of ProZinc her number are dropping at the nadir anywhere from 173-270, not ideal but increasing the dose gives me numbers that I am uncomfortable with at times especially when I am unable to monitor her while at work or sleeping at night. I am considering switching to Lantus. I would appreciate anyone who can share their experience about switching from ProZinc to Lantus.

Thank you.

I did switch from ProZinc, but I am using Levemir. I think I am seeing better progress on Levemir than I did with ProZinc. Bud doesn't drop as fast as he used to, and I think overall his preshots are coming down. He's been a tough one to regulate. We tried ProZinc for almost 5 months and have been using Levemir for a little over 3 months now.

Hi, ALexandra, I switched from Prozinc to Lantus. My preshots were always on the high side with Prozinc even when my nadirs were good. Then, for some reason my nadirs were not too good anymore. After about 6 months, I decided to try Lantus with some recommendations from this board and a few vets. I have found that it was an improvement for my cat. Although my cat can be variable at times, usually her preshots are much better and nadirs are better as well on Lantus. She spends more time in an healthier range on Lantus. For her, Lantus was a better option.

With any cat it can take some time to get regulated, regardless of the insulin. ProZinc is a good insulin. I believe the stats are that in a majority of cats, it seems to have a duration of about 10 hours. Lantus and Levemir both seem to last about 12 hours, although for any insulin, the duration will vary depending upon the cat's body. Cats have fast metabolisms, so having a long-lasting insulin is important because it provides longer control.

Many people do switch from ProZinc to Lantus or Lev. If you decide you want to make the switch, you might want to use up your ProZinc first. It's up to you.

I started out on ProZinc with Punkin, but didn't know anything at that point and wasn't home-testing, so I can't offer any input on it. One thing though, is that ProZinc is a u-40 insulin and Lantus/Lev are u-100 insulins, so if you switch to one of those, you would need to also switch syringes. The syringes need to match the insulin for accurate dosing.

Take a look at the yellow "stickies" at the top of this support group - there is a wealth of information there and it may help you figure out how to proceed. Although if it's overwhelming, don't worry. There are many experienced folks who teach others every day how to use Lantus & Lev - no one has to memorize things before they begin!
