New Member - Reading your Power Outage info and concerned on ProZinc info

This is what it says in your Power Outage info:
  • Prozinc It is recommended to store Prozinc in an upright position under refrigeration at 36º- 46º F (2º-8º C). Do not freeze. Protect from light. Per contact with Boehringer Inglehiem Vetmedica- studies indicate Prozinc should stay stable up to 28 days at room temperature up to temps of 78 degrees F. Protect from light, store in box or in cupboard.
My concern is that the box and the "Client Information Sheet for Cats" (at the bottom of the included Package Insert for Cats in the box) says:

"How should I store PROZINC?
PROZINC should be stored in an upright position under refrigeration at 36-46F (2-8C). Do not freeze. Protect from light. Use within 60 days of first puncture"

So, it is evidently not correct what you have in the Power Outage info that it can be room temperature. My vet and the tech said it needs to be refrigerated for use.

Last week, I called the Prozinc manufacturer customer service and they also said it was to be refrigerated, and said "it was not optimal" for my fridge to have been 35F at one point overnight. So, for me, that confirms the bottle is to be in the fridge
 
All I can say is that I have had quite a few occasions where ProZinc users have forgotten to put their ProZinc away overnight and the insulin was not negatively affected (given that it kept the cat in pretty much the same BG numbers as before it had been left out.)

I also can add that I have many ProZinc users who use their insulin for six months (properly stored in the fridge) before replacing with a new vial. It’s definitely good for longer than 60 days as they say.

35 degrees is not freezing
 
Also, saying that 35 degrees is “not optimal” is not the same as saying the insulin is bad. Sure, it’s not optimal because 36 degrees Fahrenheit is the lower end of their “optimal” temperature range.

I am more concerned about the shaking, but I don’t know if you already bought a new one after the shaking. If so, if it were me, I would not buy a new vial just because of 35 degrees in the fridge.

However, I generally tell our ProZinc users to get a new vial if they are persuaded that the existing one has gone bad. Definitely get a new vial if you see particles floating in the insulin or if it looks cloudy.

Very good to know it is useful beyond the 60 days! Of course, 35F is not freezing. However, they list 36 to 46F on the box, and is a standard for insulin. It may degrade, or perhaps it is a "safety buffer"

Sitting out. The vet told me a couple of months ago of one client that never put the ProZinc in the fridge and it worked.

That was earlier this year with the shaking, and I had to go online to see the Blue Pearl site to realize I'd not been told about the rolling! arrrggghhh!! I only checked Blue Pearl to verify how to give the actual shot. I used some tasty words when I saw the rollling.

The vet refunded me some money, and yes, I already got new bottles.

I'm now focusing on what hidden illness may be causing the inflammation in Rennie. I know there is a list, but I usually do not see IBD as causing insulin resistance. But, it does. The Prozinc bottle issue, I've addressed. I had shared it to say WHY it has been 4 months without any change in the high numbers
 
Some of the information may be dated in that the vials are different than insulin pens. The pens were developed so they didn't need to be refrigerated. Or at least that was the case for human insulin products. For people when they were traveling, a vial of insulin needed to be kept cold. That could be difficult to manage if your flight was grounded and you were stuck overnight in an airport and all of the food kiosks were closed. The pens don't require refrigeration.

Any kind of infection or inflammation can make diabetes much harder to regulate.
