You could be in danger of using damaged insulin

Susan B. Sloane, Explains

Pharmacist, Diabetes Care and Education Specialist

“Insulin must be protected from temperature extremes. Most people don’t realize that temperature extremes can lead to damaged insulin, rendering it less effective, or even ineffective in some cases. This can put you on a roller coaster of high blood sugars leading to extreme lows if you start increasing the insulin dose.”

Unprotected Insulin
Insulin is at the risk of being damaged everyday - in your car, at work, while you travel or even in your bag

It Works to Keep Insulin Cool and Safe!

This cap works just as advertised. We use it when traveling to keep my son’s insulin cool down here in Texas and other areas of the southwest that can get quite ‘toasty’. It’s nice to store it in our fridge between uses and simply grab it on the go. It’s a great alternative to carrying a big insulated bottle with ice sticks... Thank you!

Works every time

As unlikely as it may seem, this product works as described! I have used it for a while now, and it has never failed to keep the insulin pen below higher temperatures that degrade the insulin.

This really works

This technology actually works to keep the insulin at a safe temperature in my purse, without bulky and melting ice packs. It's convenient and compact. You can put the VIVI Cap over a pen needle for even more convenience. They are expensive, yes, but how much will an overheated insulin pen cost you? Highly recommended.
